Sterling-Irons-setSterling Irons® Single Length Set

A Unique Set Design to be Built to One Length for all Clubs to Deliver a Perfect Match of all Elements of Swing Feel for shot consistency.


  • If you are interested in the Sterling Irons® single length clubs please use the Find a Clubfitter form to find and contact a clubfitter near you, or visit
  • Single length construction ensures all possible elements of swing feel are identical for each club in the set – same MOI, same total weight, same headweight, same balance point –
    to offer the chance for improved shot consistency.
  • Identical length and lie allow the golfer to use the same stance, same posture, same swing plane forimproved shot consistency.
  • Optional high COR #5 hybrid with high COR #5, 6, and 7 irons off er proper distance for the low loft clubs at the shorter single length. Other single length sets may lose distance with the low loft clubs.
  • Conventional cast carbon steel in the #8 to gap wedge with 5* loft increments blend with the high COR design of the low loft clubheads to off er proper distance gaps and proper
    distance with the high loft clubs. Other single length sets may generate too much distance with the high loft clubs.
  • Available in a #5 hybrid or #5 iron to match the player’s desire and ability, with #6 to 9, PW and Gap Wedge and Sand Wedge.
  • Sterling Irons® Single Length clubs can be built to 36.5”, 36.75 or 37” length for each club as fit by the Clubmaker for the golfer’s comfort and preference. Contrasts with most other single length sets being created for a 37.5” length – which can generate too much distance with the high loft irons.
  • Intended to be custom fit with any Wishon Golf S2S iron shaft model and flex to meet the swing speed, transition/tempo and release point of the golfer.
  • Sterling Irons® hybrid uses standard iron shaft (.370)

  1. Hi Tom,
    I purchased a set of Sterling Irons last fall and love the fit, finish and feel of the clubs. However, I’m really struggling with clubhead speed and fear that I ended up with too heavy a swingweight so I ran a test last night.

    Using a radar head speed measurer, I took a series of full iron swings with the Sterling and my old D0 Callaway Diablo Edge iron, both the same length clubs.
    My average speed with the Sterling was only 72 mph. With the Diablo, it was 80 – a huge difference. I was wondering why my shots were a club or two further with my old irons.

    Is there anything I can do now to improve the situation? I’m going to one of your custom builders today to get fitted for one of your 919 drivers and am going to ask him, but was hoping to get your thoughts as well.

    Thanks for all the great education you’ve done for the industry!

    • If the lengths are EXACTLY the same, then the only things that could be accounting for the clubhead speed difference would be either the total weight or the swingweight or both together. The total weight is the sum of the weights of the head, shaft and grip. The shaft weight is the #1 more influential element controlling the total weight. So if the shaft weight in the Sterlings is heavier, that increases the total weight. In general, the heavier the total weight, and the heavier the swingweight, the slower the golfer would swing the club IF THOSE WEIGHTS ARE A BAD FIT TO THE GOLFER’S SWING. Some people do better with heavier weighting in clubs, many do not.


  2. Hi Tom,

    I am considering a purchase from eBay on sterling irons. The seller has said they are authentic but I wanted to confirm with you all if there was a serial number or a way to determine so I don’t get fooled here. Any help would be greatly appreciated.

    • BOB

      No way to tell. I don’t use serial numbers on the heads I design and produce. That’s because we sell the heads as components for clubmakers to custom make the sets for golfers. Because the clubmakers order all varieties of set makeups from #3 to AW down to every other head for the sets they create, there is no way we can know how to apply serial numbers so we don’t end up with odds and ends for heads. Big companies who only make standard off the rack non custom sets do that because they can pre make all the sets with the same number of heads in each set. But because Wishon Golf is so small compared to other bigly marketed companies, the chance of someone having counterfeited one of my designs is up there at the same odds as winning a lottery. So I am pretty sure what you see on Ebay would be genuine.

  3. Have the spiralock-threaded Sterling heads materialized? I’d really like to build up a Sterling-specific fitting kit. Is Diamond stocking any threaded heads ?

    • Mitch

      With the help of a very smart machinist, I have been working on a replacement connector system for the Spiralock/Your Fit connectors. This system will be able to work with any of the existing heads that people had threaded for use with the SP/YF connectors and it will work with any head with a plain hosel of 0.335″ (driver/wood/hybrid) or 0.370″ (iron/hybrid/wedge). And it will be less expensive than the SP/YF connectors. Diamond Golf has samples of these now to inspect and make a decision as to whether they want to proceed to offer these to the clubmakers this spring.


    • Thanks! I just emailed the folks at Diamond to add my support to say that I’d love to see this happen.

    • HA! That’ll probably help, for sure !! Your action reminded me of a funny story from back in the 90s when I was working for Golfsmith and heading up their component division. At the time, the company was furiously growing and expanding their retail store and retail catalog venture, which I had virtually nothing to do with. One of my long time friends in the industry is Jesse Ortiz, son of the founder of the former Orlimar Golf Company. Jesse was working for his Dad and had come up with the idea to do an infomercial for this new shallow face fwy wood he had come up with called the Tri-Metal. The infomercial BOOMED and took Orlimar from virtual anonymity to being a big company, almost overnight. Jesse realized to sustain their infomercial sales, they needed to have their products in all the retail stores. Knowing I was a VP with Golfsmith, Jesse called me to ask if I could intercede with the Golfsmith retail guys to get his stuff in all their stores.

      I went to the retail VP and one of the co owners of Golfsmith to present the case for Jesse. They both told me if they got requests for a product, then they would put it in the stores and catalog. So I told Jesse to get 10-12 of his friends to all call Golfsmith on different days to ask for Orlimar clubs. He did, and son of a gun, two weeks later the retail VP ordered his purchasing mgr to set up orders for Orlimar clubs for all the stores !! And you know, Jesse never paid me a commission on that !!! HA ! Just shows you it does not take a lot of squeaking of the wheel to get the grease !!

  4. Hi M.Wishon

    Looking for information about the new Sterling #4 iron.
    I read in the AGCP forum that this new Iron will fit more golfer with a 85 mph swing speed because of the low loft. Is that correct and are we talking about #5 iron swing speed or driver swing speed.
    Thank you for your products. ‘my customer love it ans so do I.

    • probably 5 iron. I swing 110 with a driver and was surprised when I got on any iron that I was around 80 mph. I wondered why all us stiff shaft guys are not playing regular shafts at those speeds

    • Derek
      80mph for even a #5 iron clubhead speed at a 5 iron length of 38″ is most certainly high enough for being able to use most of the S flex shafts that are made in the golf industry. However, golfer preference for the feel of the shaft is of supreme importance when it comes to making the right choice for the shaft flex. In fact I am still around 78-80mph for my own iron speed and I have been playing R flex shafts for a couple of years simply because I do get the feeling sometimes that the impact feel with an S flex can feel just a slight bit stiff and I personally dislike that feeling from years of ball striking experience.


    • Denis
      I am talking about the clubhead speed with a 7 or 8 iron, not the speed with a driver or even a 5 iron of normal 38″ length.

    • Hi Tom
      I love the new Serling series.They work great with the players that are shorter the 5’8 . I built him the 5hybrid,5iron- PW and 52,56,60 PCF micro tour . The Wedges worked out great at the single length minus 1/4 from the length of 5-pw.
      He would like a 4 iron now is there one for sterling series yet?

    • Bryce:

      That’s great to hear about your success with the Sterling irons. But do keep in mind they are not just for players of shorter height. Not at all. Yes, the 4 iron has been available for a few months now. But do be careful in terms of who you fit into the 4 iron because with its lower loft, it needs a clubhead speed with the irons of not less than 82-83mph to generate the ball speed and spin to get it to fly and carry to a distance greater than the 5 iron. It’s great to know that people play with my designs, but I never, ever want anyone to play any of my designs that they do not have the capability to hit properly.


  5. I’ve been playing these for about 2 months now, and I posted some initial impressions in this thread. Here’s an update:

    At first, I struggled with the wedges (PW and GW). They just didn’t go as far as the other clubs, proportionately. I even strengthened the lofts by 1 degree–unnecessary, as I learned. The real culprit: psychology. I discovered I was backing off the hit on these clubs because of their length. True, only one inch longer, but it felt like a lot more. But once I began to groove them, they’re fine. (They launch a lot higher, which can be problematic in the wind.)

    The lower-lofted irons were fun to hit, but I kept blocking the 4-iron. What I found was that I was gripping this club at the very end–farther, really, with the butt of the grip being in the palm of my hand. Not good, and totally unnecessary. Again, blame psychology, as I was compensating for the short shaft I was looking at, despite the fact that a well-struck 4I flew just fine. A little low, but not so much that it mattered to a 7-handicap like me.

    Finally, there was the sound of the high-COR irons (4-7). Frankly, I liked it! When you hit it pure, it sounds like a cocktail glass ‘clinking.’ I wish they all sounded like that. Weird, huh?

    And today? The wedges are fine and gap correctly. My other gaps remain fine. My carry distances are just short of my previous, conventional set (2016 Ping G), but are good enough. Settling in with these irons allowed me to fix a couple of compensating moves I’d been making, and now I’m smashing them like I’d want. I’m still not convinced I’d want to hit the SW out of a bunker, but I’ll keep an open mind for those who try it and like it.

    So what about performance? My misses–especially with the low-lofts–are way, way better. Overall, my iron accuracy is better. Grooving one iron swing has been great, too. I don’t have hybrids; above the Sterlings (4-GW) I have a Ping 3-iron, a 3-wood, and a driver. So grooving my iron swing has allowed me to spend more time in practice on those other clubs (plus my SW and LW). Nice. I’ve also picked off two bad, recurring habits (hooding the club and aiming out to the right) working together in a bad way. Why? Because I could focus on one swing for a long time. Again, nice.

    The typical trade-off in going with one-length irons is you get to hit shorter low-number clubs in return for having to hit longer “scoring” clubs. Well, the wedges are just 1″ longer; you can learn to hit them (I did). And the benefit of hitting 4-7-irons that are shorter is nothing shot of amazing. Finally, you get to groove a swing, something I didn’t even care about, nor thought mattered. Well, I do and it does. So there.

    My wife is returning to golf after a total knee replacement. I’m going to get her fit with a set of Ping Rhapsody irons. I think I’ll trade in my perfectly fine Ping G irons when I do. I’m not looking back. This is the real deal.

  6. Hi Tom,
    Just enquiring if the release date of May for left hand version is still on track, or, could it possibly be a little earlier?

    • SHANE

      Thanks so much for your interest, but the date for completion of the first production run of the left hand Sterling irons is still set up as of now for completion in mid May. I just did do the final inspection and checks on the last pre-production sets of the left hand model last week. So with production taking a minimum of 75 days, that puts us on a schedule for mid May, and that is if nothing in the form of a glitch or delay happens between now and then. But I do thank you very much and hope this can be ok for you.


    • Hi Tom,

      I have been playing your Sterlings since last April and love them, thank you again for helping me enjoy the game more. I need a 56 degree and 60 degree wedge, should I get your HM Series and make them to my length of my Sterlings, or wait until April (I Think) for the new ones to come out for the Sterling set ?

    • BARRY

      Thanks very much !! It looks like the new Sterling SW and LW will be ready to go in mid to later May, sorry that it did not get done in time for April.

  7. I think you designed them perfectly. Great forgiveness combined with single length makes the game much easier which in turn lowers scores which is what we all need. I love the sterlings and will play them until you design something better Haha. I am looking forward to what you have in store for the long end of the bag. I play the 4 iron but would love to have seen a hybrid released with it but I understand the economics of not doing it right now and hope that sales go well enough that you can further add to the collection. Thanks again Tom.

  8. I could see where he was coming from when he said he didn’t like the looks. I was playing the Ben hogan ft worth 15 blades before switching to the sterlings. The hogans were probably to best looking club I’ve playing in my opinion. Obviously the sterlings looked larger and clunkier than the hogans. It took me about a week of playing the sterlings to forget the look of the hogans and to really love the look of the sterlings. So comparing them to a traditional muscle back obviously they look different but not bad by any means. And a year later the sterlings are still in my bag so that says it all.

    • KOURT
      In a perfect world where we would have much larger sales and marketing, I would have designed a second single length model to contrast to the Sterling set as you see it. In this sense, single length is no different than conventional length – you should have different models for different player types just as has been done with conventional length irons forever. Super game improvement, game improvement, classic traditional, etc. But to do multiple models within the one concept of single length requires a lot of sales to make that be successful for each model version. Maybe someday there could be a Sterling traditional set, but for it to be an 8 iron length, which I do think is so much better, the traditional low loft heads are still going to have to be designed with a high COR face to get the distance at that 8 iron length. And I suspect many of the real traditionalists won’t like that. So at this point, I am very pleased with how Sterling is working, both from a sales and most definitely from a performance standpoint. I thought about this the other day and I think in my 31 yrs of designing clubhead models, the Sterling could be the very best iron overall that I have ever done.


    • Yesterday a couple of club members accosted me in the parking lot and started asking about single length irons. I grabbed a couple of Sterlings from my car and showed them. Both people commented that the liked the looks, especially the topline profile. So TW is definitely doing something right. I’m pretty sure that one of them will buy a set. I think I have sold 10 sets of Sterlings since they came out, and my real business is making handmade bamboo putters, not irons.

    • I agree what Tom and Kourt wrote… I still own my Slazenger Supremo (the heads are the same as Seve played in the past) with a TT DG steel shaft, they are “more blade irons” than today blades, sharper, thinner, with smaller faces than upddate blades
      a very smooth forged steel and very good feeling (when you are able to hit the ball on their very center)so there are a lot of marks on them due to the soft steel
      but, I do not sse the difference on feeling if I am honest, they are much more tough to hit, and they have very nice blade looking on my bag and behind the ball BUT I think the Sterling are at the same level of beauty (in another way) but much more appreciated when playing the ball, on feelings, results, facilities , game improvements etc….you made a very great job Tom, and I can appreciate to its higher points, if my golf game is bad its only due to a very poor swing or a wrong strategy, I am sure of it because they forgive many mistakes.
      thanks to you

  9. Tom thanks again for all of your time spent answering questions and educating us in this great game. I’ve read all I can find that you’ve written about muscle back irons vs game improve irons. I know there are plenty of myths about muscle backs being more accurate or consistent than cavity backs and I’ve read all your articles dismissing these claims. One thing I haven’t found is any info regarding workability. Why is it that people believe blades are more “workable” than cavity backs, and is this claim valid? I can’t imagine why that would be the case but I’d like to know your educated response on the subject. I think my sterlings are the most “workable” clubs I’ve ever owned mainly due to the ability of set up ease. For example a back of the stance low draw with a conventional 5 iron vs a conventional wedge are extremely different positions due to the shaft length variable Where the sterlings a low draw position is the same for every club.

    • KOURT

      I’ve always been one in my field to not believe any of these claims that some people believe muscleback irons to be able to “work the ball” more effectively or better than a game improvement iron. We do have to separate one small type of game improvement iron from this, that being the thin face, high COR game improvement iron. While you can still work the ball with such an iron, the thin face does change the feeling of impact so much over a thick face iron that many people will be confused and think the feel difference is meaning they are not working the ball the same way.

      But if you have a normal >3mm thick cast stainless steel cavity back face and a much thicker cast or forged muscleback iron, from all my work and observations as long as the offset and loft are the same in the two irons, the workability is the same and there is no advantage for the muscleback. To people who react to that with a “don’t confuse me with the facts, my mind is already made up” , I tend to use this explanation: Think about how many tour players use a cavity back iron – at last count it was around half of the PGA Tour. Do you really think that all these guys would use a cavity back iron if they could not hit an intentional draw, fade, high or low shot when they needed to ? Tour players work the ball frequently when they play. If there really were an advantage to the muscleback, I tend to think that you’d see everyone out there playing a muscleback iron. But they don’t and they still work the ball just fine.

      People sometimes confuse the MOI of an iron with workability. They think that an iron has to have a low MOI (muscleback) to be able to work the ball better. POint is, the MOI of a head never even comes into the picture until you hit the ball off center. If you hit every shot on center, there would be no need to engineer a higher MOI into some iron models. You cannot work the ball unless you hit the shot ON CENTER. And if you hit the shot on center, workability is the same for a cavity vs muscleback, provided the offset and loft is the same on both heads.


    • Tom,

      A couple clarification questions:

      “Workability” (if that’s a thing) is about club path and face angle at impact. If you have a square face and a slightly inside-to-out path, you’ll draw it a little. That should be the same for a game improvement or a blade. The only thing that gives me pause is the possibility that a high-MOI iron head would be more difficult to control with the fine muscle movements of your hands. High MOI heads resist twisting at impact, but they also resist twisting in the swing (at least on paper). Maybe great golfers have fine tuned their swing so well that the additional head MOI makes it more difficult to feel the exact face angle through the impact zone? (I’m really reaching here)

      The part of your reply that I’m questioning is the idea that you have to hit the ball in the center of the face to work it. If I mishit the shot slightly with an in-to-out club path, it’ll still draw. The shot might come up a bit short, but it’ll still draw, right? Will it draw less? Did I misunderstand your statement?

      And half of PGA tour players DO use muscleback clubs… so why do they stick with them if they could mitigate their mishits by switching to a small cavity back with no downside?

    • BRENT
      Yes, you are really reaching there in the first paragraph. When you talk about a high MOI head, that MOI which dictates how much the head twists in response to an off center hit is an MOI that HAS NOTHING TO DO WITH YOUR HANDS ON THE GRIP OR YOUR RELEASE OF THE CLUB. The MOI that controls off center hit twisting is the MOI about a vertical axis through the center of gravity of the head. That is an axis of rotation that has hnothing to do with the hands on the grip, it only is “activated” when the head hits the ball off center. There is one other MOI of a clubhead which is defined about the axis of the center of the hosel bore. This is the one that could relate to the hands on the grip because the shaft is right on that axis of rotation. Theoretically this MOI about the centerline of the hosel bore could be affected by the size/blade length of the head. Longer blade providing more resistance to rotating the club than shorter blade length. BUT in terms of REAL RESISTANCE TO THIS ROTATION, the differences in iron head size are so insignificant to this MOI that it really is a non issue. Only if you had an iron that had a blade length approaching a hockey stick would this MOI about the bore have an effect on the golfer’s release.

      On your other point, as a player you cannot possibly count an off center hit as a way to work the ball because that shot shape that comes from hitting the ball off center is a shot shape you cannot count on for a specific amount of draw (or fade on the other side of the head). If you try to work the ball and hit the shot off center, you just blew up your intended shot and the ball could end up where you did not intend it to. You can only count or compare workability for shots hit on center. Also not all players use the same swing technique to work the ball. For a draw you may try to swing more inside out, while others strengthen the grip and use their same swing, while others change ball position and others try to have a different hand position at impact to open or close the face slightly.

      What they all have to have in common to work is the shot has to be hit on center to then see ONLY the effect of whatever the swing/grip/release change in the swing resulted in for the worked shot. So you are right in saying that workability will always have everything to do with your swing change, a little to do with the face design and nothing to do with the head’s weight distribution design.


    • OK, fair point. You have to move the CG of the head (toward the heel or toe) to impact how the face closes throughout the swing. I know you’ve done a lot of testing on this front and have concluded that you have to move it a LOT to really make noticeable changes in ball flight. A higher MOI of the head isn’t changing the CG of the head. I concede that point.

      On my other point, I think we’re saying the same thing in slightly different way. I wasn’t saying that you’d TRY to hit it off center to work the ball… I’m saying that it doesn’t matter if you hit it off center. That if I have a square face and an inside out swing, that it’ll draw whether I hit it in the center or not. It seems reasonable that a blade and a GI iron will draw the ball the same amount if both clubs strike the ball with a square face and 1 deg inside out path.

      If those same 2 clubs with the same swing were both struck 1/2″ off center, then they’d both still draw the same amount, but the GI iron shot would go further than the blade.

      The other examples of ways to work the ball are ultimately only altering those 2 variables (path and face angle). Strengthening the grip would impact the face angle at impact… a 1 deg inside out path with a club that’s now 2 deg closed at impact would result in a 3 deg face-to-path angle which would increase the draw. I don’t see that any of those would impact a blade any differently than a GI iron.

      So I’m agreeing… no difference that I see in terms of “workability”. Might just be a confidence factor and the ever-elusive “feel”. Though I’ve never understood how a tiny little head with a super skinny top line inspired any confidence. It has always struck me as opposite. “How am I possibly supposed to hit a good shot with this tiny little thing?”. It would be like playing tennis with a badminton racket. Doesn’t make sense to me.

    • Brent

      Back in the 1980s, former Australian tour pro David Graham wrote a book about golf equipment. Boy was that proof that tour players should stick to using them and not discussing them ! Anyway, in his book Graham extolled the virtues of muscleback irons and denigrated what back then were the relatively new deep cavity back forgiving irons that were coming on strong in the game. His belief was that in playing a small unforgiving head golfers would get better, sooner because they would know they had to make better swings to hit it on center to make the shot play right ! I read that and laughed – “ok, David, like you think that if I have a larger game improvement model that I don’t try my hardest on every shot to hit the ball on center ??!!” From that I remember doing talks at seminars referring to the “Parris Island/David Graham boot camp approach to clubhead selection – it has to hurt to be right !”. Many of us, try as we might, just can’t make consistent swings like tour pros can !

  10. Shame about the looks. Would have bought a set if they looked better at my feet. Shame, I really liked everything else about them.

    • I would be interested to hear what you did not like about the look of the Sterling irons. Since their introduction last April, we truly have had more complements on the looks and cosmetics of this model than any other iron I have designed for many years.


    • it is only a matter of taste
      I find them pretty nice and handsome as someone took an extra care to every aspect of those great clubs, esthetic as well.
      I love them even on their look !
      I think I know about who is the Master of this achievement (sorry for my poor English)
      Everyone to his taste, that’s all !

    • I agree. Everyone to their own taste. Some prefer the players blade look and don’t like anything else. I love the look of the sterling irons, the shape, design and craftsmanship. No unnecessary “bling” badging like other OEM cavity back irons. I like the finish as well, without all the unnecessary chrome like other clubs.

    • Yes, aesthetics are really in the eye of the beholder. I personally think my Sterling irons are some of the prettiest, sharpest looking clubs I’ve ever owned, but that’s me. There is no way that everyone can be satisfied with looks just as everyone has a different opinion on performance.

    • Thank you Bob, much appreciated ! Your comment highlighted the fact that in my career, I was always the one who had to make all the decisions for the concept, design, and cosmetics. So when it is not so great in the eyes or mind of the beholder, I am the one to toss under the bus! Once in a while years ago I used to think it would be better to have committees of people to decide on the things like the name or cosmetics so if it looked like crap, they could get the heat !! But then I realized that having all that autonomy in my work as I always have had is a better way to go in the end! Thanks again and the very best to you in this great game !

  11. Hi Tom,

    I got fitted up for a set of Sterling irons and they are just fantastic. I have had Callaway, Mizuno, Cobra irons in the past and been fitted for all.

    But with my previous irons, I always struggled with the 4 and 5 irons.

    The Sterling irons have brought back the fun to my game – they are more accurate, more forgiving and longer. I’m hitting the 5 irons out to a 170metre carry distance – which is around 189 yards. I’ve never been able to do this with a 5 iron, but can now land the ball on greens at that distance at least 7 out of 10 attempts.

    I’ve now ordered a 4 iron as well.

    My son, who is not far of being a scratch player, took my new Sterling irons out yesterday for a game and thought that same thing I did. Much easier to hit than his current Mizuno Mp15’s. His “bad shots” still hit the green. He said he just needs to get used to the hotter face on the 5-6-7 irons for when he does a chip and run shot around the green as he was getting more carry and run than with the Mizuno irons. Still scored well at 3 over par.

    He’s going to have a few more games with my clubs, but looks like he is going to want to be fitted for his own set from 4 iron to PW.

    By the way, your Mid Sized Wishon grips are great. Beautiful feel and very nice in the hands – I’ll be sticking to these grips as well.

    • MATT:

      Thanks so very much for taking the time to stop by and share your comments and experience with the new Sterling irons. I can assure you that there are not very many things better than being able to read and enjoy what you wrote about your results with the new irons ! I just knew we were onto something a little better when we decided to do this based on a shorter length than what anyone had tried before with a single length set. Yes, the high COR face of the low loft irons makes it work, but the key to this is really in the fact that most all of us can hit an 8 iron length more on center more of the time than we can lengths that are longer.

      Thanks so much again and the very best to you and your son in this great game !

  12. Hey Tom will the new sw and lw have the micro grooves and the knockdown grind like the hm wedges? If they will I know many that would add them to their bags. If not you really should consider adding that stuff last minute because your hm wedge is literally the most versatile wedge I’ve ever played and would love to have a wedge that versatile that would match the sterlings.

    • KOURT

      The new Sterling SW and LW will match the scoreline configuration of the other irons and wedges in the set. It will have the zero bounce heel grind that is on both our PCF and HM series wedges but it will not have the center sole knock down grind that is on the HM wedges now.


  13. Thumbs up for the Sterling 4!

    With my iron swing speed in the high 70’s, I was afraid that it wouldn’t work for me, but it’s great. I get 180-ish (carry + roll) with the Sterling 5 and mid 190s with the 4, so the gapping is just what I want. The ball flight is just fine. I’m not going to throw it over a close-in bunker, but I can find a way to get it there.

    One of my customers, with a somewhat lower swing speed than me, is happy with his 4 too.

    The 4 hybrid is now out of my bag. Anywhere inside of 200, I’m now holding an easy-to-hit, accurate Sterling.

  14. Hi Tom,

    I live in Australia and have been very interested in your Sterling clubs, reading everything I could find about them as well as all the video reviews on Youtube. In fact, I am getting fitted this weekend for a set. My son is also very interested in the Sterling irons and will be testing the clubs with me this weekend when I am getting fitted for them.

    My son is low single figure handicapper and aims to become good enough to be a Professional Golfer, working in the golf industry. Be that as a Teaching Professional or on tour. He has learned how to build his own clubs, from the Wishon fitter we are seeing this weekend as well as becoming qualified in many other aspects such as fitness, nutrition etc and working with psychologists.

    He currently uses Mizuno MP15 irons and as such he was wondering if you were going to design and release a Pro set of SL irons in the similar vein as the MP15’s being a muscle/slight cavity back style from 4 iron down to the wedges. His swing speed with the 7 iron is around 95mph. So according to your advice that a 85mph swing speed for a 4 iron is needed, I don’t think swing speed would be an issue with using a single length 4 iron or maybe even a 3 iron?

    Anyway, just thought I would ask if a Pro set was on the drawing board, and if so, when would a release date be? If not, then I guess it will depend if he likes the current design or not. Though, he would prefer to go with your Sterling irons as from all reports, the Cobra one length irons seem to have issues with distance gapping from 6 iron to 5 iron to 4 iron, whereas your design – well, no one it seem has complained about distance gapping with the sterling irons.


    • MATT:
      Thanks very much for your communication and for your interest in our company and the Sterling single length irons. We’re very pleased that you have done the research and decided to be fit with a set of the irons. We’ll be very interested to hear how you like them when you get a chance to get used to them and hit balls and play a few rounds.

      I understand the market for a more traditional set of single length heads. If you have lots of money, the wise thing is to start right out with a separate design for traditional lower hdcp/higher clubhead speed players as well as a set for the game improvement market. Cobra did that of course. We’re not quite in that league financially or in terms of awareness and following so when I did the Sterling irons, I knew right from the get go that it had to be a set that could work well for a wide range of players. No question that there are some super good players who had been using a very traditional forged carbon steel iron who have tried and now play with the Sterlings. But I certainly understand as a player myself and a designer for over 30 yrs that there can be a need, though small, for a fully traditional version. One thing that really limits the demand or success for such a model is the fact that with no help in the low loft irons such as a high COR face to bring back lost ball speed due to the shorter length, a traditional single length set can ONLY be used by someone with much higher than normal clubhead speed, such as your son has.

      For us, I have to see that this recent increase in awareness and interest in single length will last and not fade out if deChambeau happens to not turn into the player everyone and Cobra thought he could be. If there is genuine staying power in the market for single length, then perhaps I may create a traditional version. BUt that won’t happen this year and more than likely won’t be in 2018 either because to be ready for a 2018 release, I need to be working on the design now. Sorry about that, we’re just a small specialty engineering company with a small following of astute players and clubmakers so we can’t jump into other parts of the pool as quickly as the big guys.

      Thanks so much again for your interest,

  15. Hi Tom

    I’ve had my Sterling since September and have worked on the basis that they travel roughly the same distance as the next longest club of my previous 560MC’s (e.g. 8i Sterling = 7 iron 560’s). However I haven’t tested this and wasn’t sure. I did have an inkling that the GW was relatively shorter.

    So I had a gap test today and got these results:


    It was only based on about 5 or 6 shots each, but we removed the real bad ones (there were a few) to get a decent representation. As you can see, the gaps are pretty consistent. That was quite a good thing for me to find out, and supports the theory that the loft gapping of the set is pretty spot on.

    What I did find was that my current wedge set of 50-54-58 was too close, with my 50 deg going only about 4 or 5m less than the Sterling GW. So what we did was to bend the wedges 2 deg weak and give a better gap there.

    What was also interesting was that I tended to hit the GW, PW and 9i with an ever so slight pull (say 5m) left, but hit the 6i and 5i with a noticeable (not extreme) fade ((5-10m). We concluded that I was probably sub-consciously opening the face a little on the long irons, maybe to protect against a horrid low pull and also possibly to make sure I got elevation on the shot. I guess the “same swing for all irons” concept hasn’t quite embedded itself in my head yet, but as you have said before, it takes a little while to adapt.

    Anyway, I thought people might find those gapping results interesting


  16. any update on left handed release?!?!?!?

    • RALPH

      This week I should see the final final pre production sample sets for final inspection and checks. If everything is OK, then a production order can be placed and if so, we maybe should see these by mid May. So the thing to do is to cross your fingers in the hope that the final pre production sets are good with no changes or corrections required !!

      Thanks so much for your interest,

  17. Tom, last winter I was fitted for a complete set of Wishon clubs by Jim at Von’s Golf and I can tell you that I have never hit the ball better….especially the 771 CSI irons he built me. Flash forward to today and I want to get a set of Sterling Irons, but sadly Jim is retiring (happy for Jim). Jim was a very intuitive fitter but never told me my specs. Is there anyway or anyone who I can send my 8 iron to and have them duplicate these specs into a Sterling iron set? My 771 CSI 8 iron is real magic wand and it would be great if the length, lie, swing weight and grip size could be duplicated in my Sterling set. Thanks.

    • MATT:
      Yes, I heard that Jim was retiring. Jim and I go way back together. We were both PGA asst pros at the Peach Tree CC outside of Sacramento way back in the 70s and I do think it was my influence of already being a serious club repair person that triggered Jim into learning the skills and focusing on equipment in the last part of his golf career. Since Jim and I are about the same age, I am also retired although mine is a SEMI retirement – I do a lot of work with my Sterling single length design which includes fitting and building sets for a couple of direct sales clubmaker accounts. So you could send me your 8 iron and I can measure all the specs so they could be duplicated in a set of Sterling irons that I would be glad to make for you myself. If that works for you, you can send the 8 iron to me at 251 Horse Thief Lane – Durango, CO 81301. And for any correspondence you may need related to that or anything else, use .

      Thanks very much,

    • Thanks for the response below, Tom. I’ll commit the funds and send it to you in the next week of so. Not wanting to let my own misconceptions about who I am as a golfer muddy the waters, I deliberately asked Jim not to tell me what he set me up with. This worked out pretty well until now, when knowing the specs would have been helpful. Never thought Jim would retire on me. 🙂

    • Matt
      And if you want, I can keep the specs of the 8 iron mute so you won’t know what they are and what the single length irons would be built to have. Your choice on that, all you have to do is include the instructions on a note with the 8 iron.

  18. Good Day Tom,

    My name is Alfred Rheeder from South Africa. I am currently a 4 handicap. I played collegiate golf in the USA for 2 years – albeit over twenty year ago! I hardly play during the year due to work commitments, but I endeavour hard to “catch” up during our summer holidays. I have been using the Sterling Irons and the the 919 driver with the JumboMax medium tour sized grips for the last 4 months (summer). I have been a “traditionalist” at large but have literally jumped ship! I would like to provide you with some feedback.

    1) I got used to the irons very quickly and I have had very positive results with them. They are great.

    2) The distance gapping is spot-on. I have the same or marginally longer than average iron shot lengths compared to my Ping S56 irons. I do struggle with the consistency of my distance control when hitting PW – SW. Enough practice will take care of that. I am eagerly awaiting the 4 iron I ordered!

    3)The 919 driver (44.5 inches) is awesome. Noticeable and measurably longer than the Ping G30. The correct fitment has lead to an increased in my avg. smash factor.

    Everyone I have played with tried the irons. Occasionally the only adverse feedback I got resolved around the sound and feel of the High COR 5-7 irons. I personally got used to it very quickly. However I always fiddle and I recently inserted / wedged I type of dense rubber at the back of the clubs without detracting on the look of the clubs. Since then I have not heard any negative comment again. In fact I personally adore the 5-7 even more! A type of insert that alter the “cling” sound and decrease the “vibrational” / hot feel might be something to consider in the future.

    Thanks for quality products and fitment. Least of all I want to commend you for the factual / ethical marketing. It is a fact that in most cases it will not lead to extraordinary financial wealth….. Every time I see the TV ads for the new Taylormade M driver or Callaway Epic drivers I cringe……. Then again I live in “dark” Africa and I might not be aware of changed driver/wood COR and volume regulations….. 🙂

    Lastly Tom, I would like to make use of the opportunity to wish you all the best for the future (after all the recent changes).

    PS I followed Rory Mcllroy on the Friday at the recent South African Open that was played in Johannesburg . To my surprise I spotted two up and coming South African youngsters blasting 919 Wishon’s of the tee..


    • Alfred

      Wow, how nice it is that you took the time to let me know about your experience with my models. That’s really nice, no its more than that. Thank you. I can also assure you that you are right in that one’s wealth and remuneration is not proportional to the level of honesty and integrity that I try hard to offer to people who just want to know the facts about golf clubs and how they work and how golfers need to buy their clubs to get the most from what they bring to their efforts to play this great game. You know, when I was a kid and dreamed of working in some way in golf, I used to watch the British Open and wonder if I would ever be able to experience the international side of the game. And I must say that some of my best experiences are being able to make friends in golf who are all over the world from different areas/cultures and we all have this thing in common we love the game and we are hooked on its equipment. It’s one of the most enjoyable things in my work and I thank you so much for taking the time to dig us up and display faith in what we do such that you play one of my designs. Best wishes to you in this great game!


  19. I see there is a 4 iron in the Stirling single length clubs. Will there be a 4 hybrid the same as the 5 hybrid. If there is a 4 hybrid will it still require an 85 mph swing speed to work correctly

    • DAVID
      No there will not be a 4 hybrid, only a 4 iron. The reason is because since the 4 iron requires an 85mph clubhead speed with the iron to properly elevate it to carry properly, we feel that golfers with that much speed are not going to be golfers who would prefer a hybrid over an iron of the same loft. So no 4 hybrid is going to be done.

    • Hello Tom!
      Any update on when the left hand version will be available?

    • Hi Philip:

      Thanks for your continued interest in us for getting the LH version of the Sterlings done. The final pre production inspection samples are due to me @Feb 10. If all OK, then add 75 days from there to get to the ship date to us. So if all happens to plan, early May would be the best we can do. Not as soon as many would like, but there is still a lot of golf after May !

      Thanks much,

  20. Hi Tom,
    Happy New Year!
    I have a junior girl golfer, 12yrs old, Height=157cm, wrist to floor (Left)=77.5cm measured wearing flat sole shoes on hard surface, right hand golfer, Weight 42kg, 7 iron carry=100m, Driver 12 Loft carry=160m, plays off 3.9 handicap. Would you recommend your Sterling Irons® Single Length Irons for her? If so 5H to SW set? rather than 4Iron to SW set. Shorter length irons than the standard? Would it benefit her game for more consistency? What shaft from your product do you recommend to reduce the weight of the irons? Thank you!

  21. Tom, I’m a club maker in Adelaide, Australia and purchased Sterling 5-SW sometime back, you may remember my posts referring to using TT XP95 S300 #7 taper tips shafts and tip cutting 1/2″ and making to 36.5″.

    My thinking behind purchasing the Sterling iron set was to assist in my recovery from my FULL SWING YIPS affliction, I thought as with my current Callaway Apex forged irons, as the iron length got shorter, I had to better chance of getting the club/swing started rather than club bouncing uncontrollably along the ground for up to 12 inches, it wasn’t pretty and I had to walk away from the game I loved for periods of 3 months to get my anxiety levels to subside/reduce.

    Anyway, I gamed the Sterling irons for a few rounds but as my Senior Pennant match play season was about to start, I thought it was better if I stuck with Apex Forged.

    I’m nearing the end of my yips recovery, maybe a few months away but am still intrigued how your Sterling Single Length iron set can help me further to recover.

    You see, for my recovery, I actually changed my setup routine so that it had NO PAUSES, it’s all synchronised and has specific steps, but honestly, with 2 practice swings from behind the ball, then walking in from the side and just swinging has greatly improved my ball striking and now hitting the ball better and longer than ever before, down to 5.8 h’cap and can still drop more.

    My routine is now all about letting the mind and body find it’s optimal position next to the ball, I suppose my body is auto compensating as the length of the shaft increases or decreases to find the ball position.

    With your Sterling iron set, I could just walk-in exactly the same with each iron no matter of the #. When I initially gamed your Sterling’s, I was sub-conscientiously changing the ball position and really struggled hitting the #5 and #6 irons, hitting tops and thin strikes for obvious reasons.

    When I tried hitting the Sterling’s on the range a few weeks back with my new routine, I suspect my mind/body were automatically picking the same ball position for all irons as I was hitting much cleaner and hitting same/similar distances as my Apex, maybe Sterling’s were a tad longer and flushed.

    So Tom, thank you so much in my recovery, I haven’t used the Sterling’s much but they MADE MY THINK ABOUT THE CONCEPT OF THE STERLING’S which in turn improved my setup routine.

  22. Tom, I’m intrigued by the single length concept. I wonder if this might address the drop-off in my distances? I currently play Mizuno MP-53 on GD X100 stepped up 1″. from LW (100 carry) to 8i (150 carry), I’m gapped nicely in consistent 10yd steps – but then the gaps start to compress and become less predictable, topping out at 180 if I pure my 4i. By chance, is there a club fitter you’d recommend in the SF Bay Area who might have a set to swing? Many thanks!

    • RYAN
      Forgive me I am out of the office as I answer your comment and question so I do not have full access to everything I do at the office. If you do to the FIND A CLUBFITTER search tool on (it’s right in the middle of the home page) and you input SanFrancisco you will see two guys in particular that I know very well and can assure you either one will do a superb job in your fitting analysis. One is Michael Clark in Berkeley and the other is Stan Morovia at the McInnis Park driving range on Smith Road off 101 in the San Rafael area. You’ll see their contact numbers when you read the page for a SF search on the locator. Both are really good so whoever is closer to you is probably the one to call and set something up. Call first to ask about Sterling demos – I do not have the information as to who does and does not have demos of whichever model because all the clubmakers are independent – they have no ties to us or any company so they make their own decisions for what models/companies they wish to stock and work with. Bet that you will hit the same number irons in Sterling longer than your current irons because lofts are staggered differently in the Sterling to do our best to ensure proper distance gaps between irons which for most players the irons do that fine.


  23. I acquired my Sterling irons (5 through SW) in October and have played about seven rounds with them. I absolutely LOVE the feel and the way the ball just jumps off the club face, especially with the lower lofts. I hit my Sterling 5 iron every bit as far, if not a little further than my conventional 5 iron. The distance gaps are good, but it does take a bit of a mental adjustment to put the ball in the same position for every club. I cannot wait to play a full season with them and I am really excited to get the lob wedge and the four iron too. I keep annoying the guys at Clubmaster about getting those two clubs to me as soon as they are available.

    • Bob:

      Wow, what a nice comment for me to be able to read! You mentioned just about every point that a golfer who is on the fence about going with a set that could be a question in a golfer’s about “could this be for me?” And from my standpoint as the design guy, you hit about every point in your comments I tried to aim at in my work. How nice and thanks so much for your support and interest and enthusiasm. Best wishes to you in this great game !

  24. For the 3 different length options do you use 3 different weighted heads in order to ensure the swing weight remains constant? The reason Iask is that I have the opportunity to get a set second hand but built to the shortest of the 3 spec lengths but as I am using +1″ irons normally being 6’4″ I don’t want to go ahead if the clubs at the longer length will be very heavy – I did a quick check and the irons seem to be about the same length as my Callaway Apex graphite shafted irons at +1″

    • Thank you David for your interest. Much appreciated for sure. The spec weight of the Sterling heads is 274g with a small plus/minus tolerance. Every head is made with a weight bore at the bottom of the shaft bore to allow the clubmaker to final tweak the headweight to achieve pretty much whatever swingweight he needs to make the clubs to fit the golfer. That’s the custom part that has to come along with the choice of either a 36.5, 36.75 or 37 inch playing length. No question, with the weight bore it will allow the clubs to be fit and made to about 90% of all golfer fitting requirements. If 37.5 were more comfortable to you and if your shaft of choice were a 120g steel, the swingweight will come out a little higher. BUt depending on your tempo and “golf strength” as we call it, the swt that may come from a 37.5 length + 120g shaft might not be an issue for you. Hope this helps a little and thanks again for your interest.

  25. Sterling vs. In1Zone shootout – no contest. I bought a few In1Zone single-length heads, thinking it would be nice to have a value-priced option for people who are put off by the price of premium clubs. I built them with graphite shafts that I know well, having played with them on my own set for years, to the same specs as my personal Sterling set. I hit about 50 shots on the range, using my (soft) game ball, not range rocks. After a few shots I was able to hit reasonably good shots, but they never felt good. I really wanted to like the In1Zones, but I just didn’t. I had to stop hitting them because my hands were hurting. Even flushed shots didn’t feel right, nothing like the pure feel of Sterling heads. I had to spend the next half hour hitting a Sterling to erase the terrible feel from my hands. Design and metallurgy matters. TW is the master.

    • MITCH

      Ahhhh, what a nice comment for me to have the chance to read !! Thanks for putting the Sterling irons to the test so you could have the chance to know and then be able to tell golfers exactly what you found. That’s nice to hear !


    • This is interesting. I have been very intrigued by the Sterlings since release however I only picked up some 560MC’s 2 years ago. My OH wouldn’t let me spend another lump of our savings on new clubs so I also went with some budget single length in the Pinhawks.

      Really enjoying the concept and playing well with them but now my intrigue is stoked again! If Sterlings play nice I might need to get myself a fitting ASAP!

  26. I noticed in one of your responses tha you mentioned there was a new SW and LW in the works targeted for April. What is the difference between the current SW and the new one? Thanks for your time in responding in this thread.

    • TREY

      The current SW in the Sterling set is designed with a face profile shape that looks like the other irons from the 8, 9, PW, GW. The new wedges will have a more traditional SW/LW face profile shape such as what you see on all the standalone wedge models like the Cleveland, Vokey or our HM Series and PCF wedges.


  27. Awwwwwwwwwright!

    Before I purchased a set of Sterlings (4-GW), I was skeptical about the high-loft irons. I liked the idea of the shorter low-lofted irons, but I wondered if I’d lose something hitting such long wedges, especially. Then, after getting them, I really struggled with the PW and particularly the GW. I was accurate enough, but I was hitting them short….SHORT. I even strengthened the lofts by a degree on the GW and PW. But….

    It turns out that my skepticism was NOT ‘proven’ by the results. Instead, it was CAUSING them. After getting in the groove with the Sterlings, I wondered why I was still struggling with the wedges. But as I played and practiced, I got much better at putting the SAME swing on every club. Boom! The wedges fell right in line. (It helped with the fade I was unintentionally putting on the 4-iron, too.)

    Give these some time. Once you develop consistency, they’ll perform for you throughout the set. Seriously.

  28. Hello Tom,
    I’m playing the Sterling irons since December. The 4 iron -PW. I think I’m the first here in Germany who play the 4 iron and it is really unbelievable to hit the irons with 36.5 shaft as far as my old clubs with 0.25+ lenght. Thank you very much for the great clubs!

    • VOLKER

      Thank you VERY MUCH for taking the time to write and tell us about your experience with your new Sterling irons. We really do appreciate that and I must tell you, as the designer it is a BIG PLEASURE for me to be able to know that you like the irons and they are helping you enjoy this great game a little more. Thank you so much for letting me have a big smile on my face as I think about you feeling good about playing with these new clubs !!


  29. What is the lowest loft 5 hybrid available in the sterling set from the hand select service.

    • Kourt
      It is possible once in a while to find one at 21* loft.

  30. Hi Tom, as ever loving the work!

    I noticed that ‘normal’ iron sets tend to increase in swingweight towards wedge end of the bag. Is this because club makers can not match swingweight in a variable length set or is it done on purpose? Also, do the Sterling irons mirror this same trend, or is swingweight constant throughout?

    Many Thanks

    • BEN

      Normal or conventional iron sets do NOT typically increase in swingweight down through the set. Only one golf company to my knowledge has offered ONE model made that way. Ping began to offer a progressive swingweight set in 2016 which was their attempt to try to simulate what happens when a custom clubmaker makes a set in which all irons in the set are matched to the same Moment of Inertia. MOI matched iron sets has been exclusively the domain of more advanced custom clubmakers. And if you take a true MOI matched set and put each club on the swingweight scale, their swingweight does gradually progress upward from low to high numbers in the set. No other companies do this as the norm has always been to make each iron have the same swingweight.

      This is a very long matter to explain but I shall try to do it as concisely as I can. In a set that is made so each iron is a different length, the ONLY way you can achieve a match of each club having the same MOI is to make them progress slightly upward in swingweight. But when you make a single length set, now you can have each club end up with the same MOI by having the same swingweight. The fact that the irons all are the same length eliminates the need for swingweights to increase through the set. So when you have a single length set in which all irons are the same length, same shaft weight, same headweight, same grip weight, same balance point, they AUTOMATICALLY under the laws of physics end up with the same MOI.

      Progressive swingweight is the only way you can achieve MOI matching when all the irons are made to different incremental lengths. Single length means you automatically achieve an MOI match when the swingweights (headweights) are all the same for all the single length clubs in the set.

      Hope this helps,

  31. Tom,

    I am getting ready to buy the Sterling set of clubs. This will be the set make up if I go with the standard set.
    Driver 10.5
    3 Wood 15

    5 hybrid 23
    6 iron 27
    7 iron 31
    8 iron 35
    9 Iron 40
    PW 45
    GW 50
    SW 55

    My concern is the gap between the 3 wood and the 5 Hybrid. I do not swing fast enough to go with the 4 iron. I was thing about going out and buying a regular hybrid but it would change the whole same swing idea. I had a question for you first. If my swing is 75 MPH with all the clubs and I bought a second 5 Hybrid and had it bent to the 19 degrees would it still give me the gaping i would need?

    • TOM

      Sounds to me like the club I would put in there between the 15* 3-wood and the 5 hybrid in the Sterlings would be a 19 to 20* fairway wood at a length of around 40″. That would either be a weak 5w or a stronger 7w head. You do NOT want to mess around with trying to bend a second 5 hybrid and make it at the same single length as the other irons. Your 75mph speed is not high enough to properly elevate a 19* head built to a 7 or 8 iron length. That short of a length for that low of a low requires at least an 85mph speed to elevate the shot enough to get it to fly and carry as far as you want to be longer than the 5 hybrid.


  32. Tom…. is the Sterling hybrid based on another of your previous designs or is it something entirely new? I believe I read previously you suggested it be built 1 inch longer then the set? So at 37.5″.

    Thanks Tom.

    • JEFF

      The #5 hybrid in the Sterling single length set is based on the shape of our high COR hybrid models called the 775HS. But because the headweight of the 5 hybrid is 274g, same as all the other Sterling irons, we piled up all that extra weight on the sole to be able to lower the center of gravity more to help get the ball up to fly at that single length. And I have never advocated the 5 hybrid in the Sterling set to be any different length than all the rest of the irons in the single length set. That’s why the head weight of the hybrid is the same as every other clubhead in the Sterling set makeup. The whole benefit of single length is . . . . ONE LENGTH FOR ALL THE CLUBS IN THE STERLING SET. With one length, you get the same shaft weight, same total weight, same headweight/swingweight, same flex/bend profile, same balance point, same MOI, same stance, same posture, same everything. That is the key to single length being able to potentially improve shot consistency and greens hit in regulation. If you deviate from that with a different length, you make that club not match perfectly to the rest in the set.


    • Awesome! May have read that on another hybrid design. Thanks Tom.

  33. Tom Wishon,

    I had a local fitter fit me for the one length sterlings. If i order them on the website it only gives me the option for the S2S Shaft. Does it matter if I do a shaft that is not a S2S?

    • TIM

      Thanks very much for your interest ! When working with the custom clubmakers, you could ask for any shaft you want that fits you and the clubmaker can order the shafts and install them in the irons. All sales of the Sterling single length irons made through are fit and built with one of the several different S2S Shaft to Swing custom designed shafts that I designed. is not a part of Wishon Golf in any way. It is an independent venture that chose to offer a custom fitting option for the Sterling irons but exclusively with the different shafts that I design. If there is a different shaft you prefer in the irons, then by all means do work with the custom clubmaker to get the irons made to your satisfaction.

      Thanks again,

    • The club fitter recommended Aerotech Steelfiber shafts for my clubs. Also the last question would be before I buy a set would be (Is there going to be a new design of the clubs in 2017)

    • TIM
      The Sterling irons will remain the same for 2017 as they are now. I will be bringing out the left hand version and I do have an optional alternative SW and LW that will have a more traditional shape ala any of the standalone wedges like our PCF/HM or like the Vokey, Cleveland, etc. But these new wedges will have the same back design as the current wedges. They are just an option for the players who prefer their wedges to be of a more traditional round/tear drop profile.


  34. Hi Tom,

    I am just at the start of my journey from standard length to single length irons.

    Running parallel to this journey I am experimenting with super jumbo grips.

    The standard weight of the Junbomax grips is 0.28lbs.

    I have had the, midsize grip on my Driver (played at 43 inches plus added lead tape for the swingweight) replaced with a jumbomax grip.

    In order to keep the swingweight the same another significant amount of lead tape has been added to the sole of the club.

    Having played the club the ball flight appears to be higher than previously. A result, I would guess, of the amount of extra weight added to the sole of the club. The distance the ball flew was similar to that previously gained.

    Would it be feasible to remove some of the extra weight, from the clubhead, in order to possibly increase clubhead speed or will this just make the club out of balance and unhittable.

    This process leads to the main question:

    The clubhead that I have had made up as trials are the 5h and PW. These have both been made up with a Normal jumbo grip, Avon Chamois, Whishon White Shaft in Reg and to my 7i length.

    Would it be possible to replace the current grips with the Jumbomax grip?
    How much weight would I have to add to equalise the swingweight?
    What effect to playability would adding little extra weight to the clubhead?

    • PETER

      When you use an EXTREMELY HEAVY grip such as one of the Jumbo Max grips, you really cannot use the club’s previous swingweight with a normal weight grip as the guideline for what the swingweight should be with the very heavy grip. If you do, you experience what you have so far – too much head weight which in turn brings about much more of a bending influence on the shaft which means too high of a dynamic loft at impact from too much forward shaft bending. When using such a heavy grip, you really are out there on a “deserted island all by yourself”, to use a phrase. In other words, you have to experiment with headweight to find whatever amount of weight addition ends up feeling like enough heft out there on the end of the shaft, but not so much that it brings about too much shaft bending. Right now with the current club, you should just start removing lead tape and hitting shots to see if you can get to a point that you remove as much as possible without the head starting to feel too head light. forget what actual swingweight that ends up being because with that heavy grip, the actual swingweight measurement is irrelevant. You need to just look for a headweight FEEL that to you and your senses feels like enough headweight but not too much and not too little.


    • I have been using 107g super sized grips on my Sterlings since day one. I like the “DTG Super Oversize Grip” from Two of my Sterling customers chose the gigantic grips too, and liked them so much that they had me regrip all their clubs with them. For me, there is no problem at all with head feel. The weight of a grip is so close to the center of rotation that its effect on the moment of inertia is minimized.

    • Thanks Tom,

      This is just what I needed to find out.

      Is it the same for below.

      The clubhead that I have had made up as trials are the 5h and PW. These have both been made up with a Normal jumbo grip, Avon Chamois, Whishon White Shaft in Reg and to my 7i length.
      Would it be possible to replace the current grips with the Jumbomax grip?
      How much weight would I have to add to equalise the swingweight?
      What effect to playability would adding little extra weight to the clubhead?

    • PETER
      Any clubmaker should be able to remove the Chamois grips and install the JumboMax grips with no problems whatsoever. I cannot tell you precisely how much weight would need to be added to equalize the swingweight because I don’t know the weight of the JumbMax grip – they make several different sizes and each one has a different weight. Also you have +/- production tolerances in the final weight of every grip to deal with. In general though, a 4 gram addition of weight on the grip end causes the swingweight to drop by 1 swingweight point. So you need to subtract the weight of the Chamois grip from the weight of the JumboMax grip, then divide by 4, then multiply that by 2 and that gives you a general idea of the grams you need to add to the head to get back to the original swingweight.

      BUT . . . . I doubt seriously if you want to get this back to the original swingweight you had before. I am pretty sure you would find that to be extremely heavy feeling. So what you need to do is to start with one of the irons only. Install the JumboMax grip. Get a roll of lead tape and head to the driving range. Hit shots and add some weight after each 2-3 hits until you get to the point that you feel that the head weight feel during the swing is too heavy. Then remove some weight and go at least a week or 10 days of hitting shots on the range and on course to see if you are ok with the headweight feel at that point. If not, keep experimenting with the weight on the head until you are comfortable with it. Then take a swingweight reading and make the other irons the same after the have the JumboMax grips installed.


    • Tom,
      Thanks very much for your answer.
      Every time I send you an enquiry I am always amazed that you can find the time to answer the question and that you are so open with your answers.
      I listened to a clip of a radio show that you contributed to recently. The show was discussing the single length concept and you were described as the most knowledgable man regarding golf club design, building and fitting in the world.
      For you to take the time to educate the general golf world as you do is just staggering.
      I cannot believe that any other CEO of a golf club manufacturer would bother to answer questions about their equipment as you do about yours.
      On behalf of all of the golfers out there, that are benefiting from your knowledge, I would like to thank you for your honesty and wish you and your family a wonderful Christmas and a happy and prosperous 2017.
      I promise that I will not bother you again in 2016 with my mundane drivel but I can’t promise that I won’t question you again in the new year.

    • Peter

      HA! It’s always been a priority for me to respond in as much detail as I feel I need to fully explain my answer because I know just how difficult to impossible it is for golfers to get good, truthful and helpful information about golf equipment. DECADES AGO I made a promise that because I struggled so much with finding answers to my questions that if I ever learned all this stuff, I would always take the time to help anyone who wanted to know the ins and outs of equipment. Plus, since I am semi retired now, that makes it even easier (and fun to do!!)

      Thanks for YOUR interest and the very best to you in this great game,

    • Hi Tom,

      Following on from our previous conversation regarding Jumbomax grips.
      I have now fitted these grips to my Driver, F/D, 7 iron, 55* and 60* widesole.
      We have had to add some weight to the driver but all of the other clubs are playing very well with no added weight at all.
      It is going to be an interesting journey.

    • Peter
      Indeed, and do have fun as you experiment with your equipment !

  35. Dear Tom,

    Owning a sterling set from André Thaon , 5 to SW, I was quite amazing to discover how they are comfortable to hit and so straight.
    The main benefits are the fact I can hit fades with confidence (I could not control them with my Mizu JPX 850 forged) and draws as well, with a rather good control…
    I own an Hybrid as well, but I have to practice it more.
    the other benefit is the comfort, it is obvious with “short” irons (I own a 37″ set, but I am tall)
    The more amazing is with “short” irons 9 to SW, with very good gaps and easy shots around greens even on chipping , flops etc… I was my main interrogation about (not on distance with “long” irons)
    at the begining I it too far with GW and SW, but now it is ok
    So I would be very happy if you intend to design a new Sterling lob wedge…
    great job anyway


      Thank you very much for taking the time to come to our site to share your experience with the Sterling single length irons. We’re very pleased to hear that the set is performing well for you ! But since you did work with Andre for the fitting and custom clubmaking of the set, I am not surprised at all to hear that you like the clubs. Andre is in my opinion one of the ten best clubfitters in the whole world, and I do mean that.

      We will be introducing a brand new Sterling sand wedge and lob wedge in the spring of 2017, hopefully around April. Andre will have those new models for the Sterling set as soon as they are available. Thank you again for your interest and your support and we wish you the very best in this great game !

  37. I think, for me, the wedges are a mix of two problems. I’m sure I back off a bit with them, so I’ll have to get over that. But I also think–especially for the gap wedge–there was too much distance between them. Although it was hard to gauge today, it appears I now have them at both the right distances and the right gaps. We’ll see.

    Carry distances:


    So, the gapping is fine. The distances are comparable to other clubs I’ve played, and the quality of my misses with the low-numbered clubs is better. The only downside is dialing in my swing on the wedges. When I make a full turn with good tempo, it flies as it should. But there’s something about standing over the ball with what feels like an 8-iron, yet with only 120 or so to carry.

    The 4- and 5-iron definitely fly lower, but I didn’t have any trouble getting them to stop. The wedges seemed to fly higher, but they didn’t really balloon. Finally, the high-COR irons have a distinct to them at impact. Noticeable, but not as loud as TaylorMade Speedblades. Less so with a tour ball than with a range ball, of course.

  38. Hi Tom,

    Last year I was fitted for, purchased and have been playing with a set of 771csi’s that I truly believe are the best irons that I have ever had the pleasure of using.
    During this period my handicap has reduced from 22 to 16.
    In the normal cycle of things I would have stuck to these irons until they were completely worn out because I like them so much.
    Unfortunately you have created a complete dilemma for me that I am certain is going to cause me problems going forwards.
    In designing the Sterling irons you have created an intriguing situation that I find myself having to explore.
    With that in mind I ordered a Sterling 5h as a demo club.
    I had it built to the exact specification of my 771 7 iron.
    My theory for this is A. I have only a moderate swing speed sub 80mph for my 6 iron and B. I love the feeling of control that the 7 iron length gives me.
    I can’t remember what length my current 7 iron but it was custom fit and I love the club.
    I received my new Sterling on Friday of last week and the first chance that I had to hit it was during my pre round warm up on Saturday.
    I must say that I quite liked the club and looked forwards to using it in my round.
    During the round I hit the club a number of times and was totally convinced that this club was staying in the bag come what may.
    I hit the club longer than the old 4h that it was replacing and due to the much shorter shaft was far mor confident and able to be much more aggressive through the ball with this new club.
    On Monday I took the Sterling with me for a lesson on the range.
    In the no consequence environment of the range I was able to see what the Sterling was capable of and WOW.
    My teaching pro said that this club was almost easy enough to hit to be called cheating and this could soon be the club that I want to hit as often as possible.
    When asked buy my club pro, who had built the club, asked me how I had “got on” with the Sterling I immediately ordered a PW to the same specification.
    What a great start to my trial

    • PETER

      Thanks very much for taking your time to come on over and share your experience with having created a Sterling 5 hybrid at your current 7 iron length. Being able to hear that you like the club is really a thrill for me to have as the designer of the models !! I am pleased to hear you like it so much and also happy to know that your teaching pro felt this is a real benefit for your game too !! Thanks so much and the very best to you in this great game!


  39. Tom,

    I love my sterling irons and I am really ready to add that 4I to my bag. When will it be available to order? I order it through sterling Irons like the rest of my set or directly from you? Also, either way, will you be able to reference the specs from my original 5-SW order to match the 4I to my set?



    • Thanks Doug, great to hear that you love the irons !! We just did begin to receive the first production of the new #4 iron heads. will be adding this to their website offering options sometime this week, I anticipate. So if you wished to add the 4 iron you can contact them and ask for it to be done. And yes, we do have the build specs from our work for that we can follow to make the 4 iron.

      Thanks very much,

  40. Got ’em today. Hit em. Played 9 holes (par 3 course). Observations:

    Set: 4I-GW with stiff shafts and stretched grips, bent 1 degree up.

    Looks: Very nice. Even though the small-numbered irons are constructed differently than are the large-numbered irons, they look like one set. You have to look very closely to see any difference–or look at the label. They look great at setup with not-too-much offset (way less than my Ping G irons).

    Feel: They feel soft for a cast club. The lower-numbered irons have a distinct ‘click’ to them at impact, but no more than my TM RSi1 irons. No real noticeable difference in feel between the ‘soft’ clubs and the ‘high COR’ clubs.

    Play: Oh, yeah. There’s something cool about looking at a 5I distance with a club a short as your 8I. But….there’s a mental aspect of this that needs to be watched. I found myself backing off the PW and GW a bit when, in fact, I should hit them with the exact same swing. The club feels too long when looking at the short distances covered by the wedges. I’m hoping this will improve.

    Distance: Every bit as long as my other two sets.

    Height/Spin: Launch angles seemed okay, except the wedges seemed high. I hit a high ball with too much spin, so I’m hoping the 4-7 irons will help that. I also hope the wedges don’t balloon, but it’s too early to tell.

    Gaps: Hard to say this early, but they seem fine. I was getting predictable distances from each club, so I think the gapping is fine. My 8I swing speed is 88mph, so the 5i didn’t present any problems. I didn’t hit the 4I on the course and couldn’t really tell on the range, so I’m not sure if I’m seeing a gap between it and the 5I. It goes lower, certainly.

    Conclusion: Two reasons for playing these irons, each with a (potential) cost. First, there’s the opportunity to hit ‘long’ iron with a short shaft.That’s definitely real here, and it’s cool. But it also means hitting ‘short’ irons and wedges with a longer shaft. I’m not convinced of that one yet, and I stayed away from the SW for that reason. Second, you play these because you want to groove a consistent swing with your irons. The offset is whether or not you can get the right distances. Well, I didn’t put much capital into the swing-grooving dynamic, but I’m not so sure now. It sure felt nice to swing it the same way every time, and the gaps seemed both real and sufficient.

    Great work, Tom!

    • Used the simulator for an hour today to check gaps.

      (Note: as long as the simulator is reliable–it posts the same results for the same swings and records relative distances between clubs–it works. It doesn’t have to be valid–where the sim results are comparable to on-course outcomes. This sim seemed about 1/2 club short using either conventional or Sterling irons.)

      Gaps were good, 10-12 yards between clubs, including the scary 4-iron. Amazing to hit a 4-iron to a comparable distance using an 8-iron shaft. But….

      The wedges were hard. Both the PW and the GW were really weak. I thought it might be attributable to a mental thing–backing off because of the relatively long shaft. But no, I really couldn’t get them out there. The PW was carrying about 20y less than the 9-iron–unacceptable. The GW was carrying another 15 yards less than that. So I bent them both strong–easy to bend!–and they performed better. But it’s weird to have a PW with the length of an 8-iron and the loft between a 9-iron and a PW. The GW was really short, too. I have to think it’s because the soft metal has a low COR, but I can’t prove that.

      As for distances, I’m getting comparable distances to my Ping G set across the board (now that I’ve bent the wedges 2 degrees stronger). But the quality of the strike is way, way better already.

      One other thing. I had a tendency towards hitting the 4-iron right. I wasn’t sure if I was blocking it or not. I wasn’t slicing it. I think I was setting up open, compensating for the really strong loft on what still looks and feels like an 8-iron! When I realized it and got the clubface lined up down the target line, boom.

      I don’t know if these clubs are anyone’s idea of a panacea, but they perform as advertised. I’m still dubious of the length of the wedges, though. That’s going to take some getting used to.

  41. I might have missed it, but is there going to be a 4 hybrid or just the 4 iron?

    • JR:

      Only a 4 iron, not a 4 hybrid. The reason is because I felt that first of all, to be able to hit the #4 even in a hybrid to achieve proper trajectory so the shot would fly farther than the 5 iron will require a clubhead speed of 85mph or more with a 36.5″ to 37″ length iron. I felt that the vast majority of golfers who could do that, and who would want a #4 for their Sterling set would prefer the iron over the hybrid.


    • Tom, thanks for the reply. I have been getting 178-180 from the 5i which leaves me about a 20 yd. gap to my adams hybrid. Would bending the 5h 4 degrees be an experiment worth trying? The thinking is to keep the single length concept as much as possible.

    • JR

      It’s a long explanation that is best made in person to show you the reason, but you cannot bend any hybrid, fwy wood or driver to change its loft. You can bend the hosel to change face angle and lie angle, but not loft. You can do a bend with an iron to change loft because we golfers always hold the iron square to the target whenever we set up to the shot. With the hybrid, wood or driver, their wide sole means that most typically we rest the head on its sole when we address the ball. if you do a bend with a hyb/wood or driver and then sole the head, that bend turns into a face angle change so the head will now sit open or closed. The only way you can do a bend on a hyb/fwy/driver and have it change loft is if you always HOLD THE HEAD SQUARE BEHIND THE BALL AND YOU NEVER SOLE THE HEAD ON THE GROUND. That’s not a good idea to do because when turning the head square, the sole is not parallel to the ground anymore. So you have to sort of hover the sole off the ground while also holding the face square. Not the best thing for shot consistency.

      Therefore, the solution to your situation is to be fit for or find a hybrid that has its loft halfway in between the loft of your Adams hybrid and the Sterling 5 iron, and have its length made to be around 38″ so it is longer than the Sterlings but shorter than your Adams. Do that and you’ll fill that gap. Now if you have a clubhead speed of 85mph or higher with the 5 iron, you could use one of the new Sterling 4 irons that is just now starting to ship to clubmakers.

      Hope this helps, thanks so much for your interest and support,

  43. Hi Tom,
    Recently I bought a complete new set Sterling Irons I5 tot SW. I really hit them well and i’m very pleased with it. I took a little time to get used to the sound.
    Now i have all the clubs the same with the same shaft length i noticed that i becomes more en more difficult for me to hit my normal fairway woods and Driver. My question is do you have a suggestion to complete the Sterling Irons set with a hybrid and driver that are complementary to my Stirling Iron Set so the huge difference in length is easier to bridge ? ? I hope to hear from you.

    • MARK:
      Yes for sure. And the need to go with a shorter driver/woods is not so much a product of the Sterling single length irons’ effect as much as it is the simple fact that all of these clubs sold off the rack in pro shops and retail golf stores are just too long for the vast majority of golfers. If your driver is off the rack and 45-46″ in length, and if you are not a sub 8 hdcp with a super smooth tempo, then you should never try to use a driver of more than 44″ length. If you are fast in tempo and hdcp above 12-14, then it should not be longer than 43.5″. Fairway woods follow in accordance to that. Most off the rack 3w’s are 43.5″ which is too long for most golfers to hit consistently off the deck. So if you go with a 44″ driver, then if you have a 3w it should not be longer than 42.5″, 5w at 41.5″. If you are above 12-14 hdcp and with an avg to faster tempo, then the 3w should not be longer than 42 and the 5w not longer than 41″.

      Hope this helps,

    • Hi Tom, Thanks for your answer about the sterling irons etc. Do you have a hybrid 4 in your product range that can be build at the same length and spec’s as my Sterling Set ? I have Sterling SW to I5 and i would like a hybrid 3 or 4 for some extra distance but only if the lenght is te same. My Sterling Iron 5 goes about 190 meters. On the Sterling website i could only find the Hybrid 5.
      Thanks in advance.

      Mark van Nunen

    • MARK:
      My pleasure for sure to help. I am sorry but we do not have a #4 hybrid in the actual Sterling product line. In our testing we found that the 19* loft required for the #4 would require a minimum clubhead speed of 85mph to properly elevate the shot to carry the ball farther than the #5 iron or #5 hybrid. We just felt that among golfers with an 85mph and higher iron speed, they would prefer to have the #4 iron and not a hybrid for that club. So we tooled the set to a 5 hybrid and then just recently we brought out a 4 iron for those with much higher clubhead speed who wanted a single length #4 to go with their set. Since you get 190 meters from the 5 iron, you certainly have enough clubhead speed to hit the Sterling 4 iron, in my opinion. Thanks very much and hope this helps,

    • Hi Tom,
      Thanks for your answer. Is it already possible to order a Sterling Iron 4 with the same spec’s that i ordered for my complete Sterling Set ? and if yes how / where can i order this club ?
      thanks again.
      Mark van Nunen

    • MARK
      Contact the person or company that you ordered the other Sterling irons from and ask them to have the 4 iron made up to match the specs of your current irons. if you got the clubs from a custom clubmaker, you can call him to ask him to order the 4 iron head and shaft and grip and make the iron to match all the specs of the other Sterling irons he made for you. If you ordered the irons through, you can contact them to order the 4 iron and they will have all the specs of your irons from which the 4 iron can be made to perfectly match the set.

      Thanks very much,

  44. Tom,

    Thanks for answering our questions! You last recommended to have a swing speed of at least 85 mph before considering the 4 iron. I found some PGA tour average stats from trackman (, and the average tour player 8 iron swing speed is 87 mph. This would mean in order to be recommended for the sterling 4 iron, you would basically need a tour player swing speed? Your the best! Can’t wait for my Christmas set!

    • TREY
      If the player were say, 81-84mph and had a really late release and also had the ability to always stay well behind the shot through impact, he could elevate the 4 iron of the Sterling set. But since these are much more advanced swing characteristics, that’s why we put that 85mph threshold on the 4 iron. Always in my 31 yrs of designing clubheads I have tried to do as much to tell golfers what they should NOT be trying to play as much as I have told them what to play for their swing characteristics.


  45. Tom,

    I have a set of Sterling irons (5-SW) and like them quite a bit. Everyone is asking about a 4-iron, and I’m glad that will be out soon. However, I’m interested in a lob wedge. Any plans to make one? My current lob wedge is quite the odd duck amongst the single length Sterlings.


    • CRAIG
      The first shipment of the 4 irons will be at Diamond Golf for distribution on or about Dec 1. How many they have on back order waiting for these heads is something I do not know. But they will begin to arrive to be shipped very soon. We will be cautioning golfers to NOT think about adding a 4 iron to their Sterling set unless their clubhead speed with the rest of the Sterling irons is at least 85mph. This is simply because a 19* loft iron at 36.5″ or 37″ in length requires that much clubhead speed to properly elevate the ball to the shot trajectory that the golfer would want to have with the club. I am designing a LW right now to add to the set. That one might make it to be available around April or May.

      Thanks much,

  46. How forgiving is the head on the sterling irons ? I have a set of 560MC, which is decent forgiveness not as much as my TM Aeroburners.

    • TAI
      You need to remember that there are two different head model design constructions within the Sterling set. The #4, 5, 6, 7 are a thin, variable thickness high COR face design so they are very forgiving because of the variable thickness face design being able to increase face flexing for both on and off center hits more than is possible with a conventional thick face design. The Sterling #8, 9, PW, GW and Sw are all a one piece carbon steel design but they are a deep cavity back. So these irons in the set would be more like the 560 for off center hit forgiveness. At the same time you also have to realize that when it comes to irons of more loft than 40*, no iron has much off center forgiveness because at that much loft, the face is tilted back so much that impact with the ball does not result in as much force into the face as it does sliding of the ball up the face.


  47. Hi Tom.

    The changes you mentioned to wedges… will those be coming out with the left handed clubs in the Spring? Any other club updates coming with the leftie release?



    • JEFF

      If I get off my duff here and get those new wedge designs done they will ! Otherwise the LH version will start the same way as the RH did and the standalone wedge shapes will come a little later. I can’t lie – being in semi retirement now means I move slower !! HA !


  48. Took the plunge! I went to my local clubfitter, hit a few 5I and 8I shots, compared them to the TM RSi 1 I was hitting, and placed an order. I asked that he wait until the 4I is available, and ordered 4I-GW, steel, stiff, 1 degree upright, stretched grip.

    The results on the indoor hitting were interesting. The 8I performed comparably; surprising since the TM is supposed to be a pretty hot face. But the real treat was the 5I. Man, oh, man, is it HOT. I was hitting it 15 yards farther with tighter dispersion.

    Two things I could not try out: first, how consistency might improve over time hitting these. Sill have a driver, 3W, and driving iron in the bag, plus SW and LW. But I’m hoping to see a bit of improvement. Second, because he didn’t have the “shorter” clubs available, I didn’t get to see if the longer 9I, PW, and GW were going to be a bother. I guess I find out, though.

    Looking forward to hitting them!

    • Did you notice a difference in peak height between the sterling 4i and your conventional 4i? I saw a review regarding the Cobra single length irons about the peak height of the 4i being considerably lower than a conventional 4i.

    • TREY

      You have to understand that when you have an iron that is both shorter and lower in loft than the same number iron is in a conventional incremental length set, it is going to take a higher clubhead speed to be able to elevate the ball more. Let me explain with examples so I can be more clear.

      In a conventional set, most 4 irons are going to be 38.5″ long and depending on the model, the 4 iron will have a loft anywhere from 20 to 23*. In the Cobra set, their 4 iron I believe is 19* loft at 37.25″ length. In the Sterling set, the new 4 iron to come will be 19* loft with a high COR face. Depending on the fitting, the single length of the Sterling could be 36.5″ to 37″ in length.

      Your clubhead speed with a 38.5″ iron length will probably be around 4 to 6 mph higher than it will be with an iron length of 37.25″ to 36.5″. With that slower swing speed with the 37.25 or 36.5″ long single length 4 iron, you won’t get as much ball speed and you won’t get as much spin as you will with the higher swing speed of a 38.5″ length. So for a golfer to get the same trajectory with a 37.25 or 36.5″ long single length 4 iron as he does with a 38.5″ long 4 iron, the golfer has to have a higher clubhead speed.

      We know from our testing that in order to hit the ball high with our Sterling #4 iron at 19* with its high COR face at 36.5″ length, the golfer must have a clubhead speed of not less than 85mph. It’s going to be the same if not higher for the Cobra 4 iron because their 4 iron does not have as high of a COR as does the Sterling #4 iron.

      Golfers who are interested in single length irons are going to have to understand that if they do not have a clubhead speed with the iron that is above 85mph, then they better not buy the 4 iron and they better start their iron set with the 5 iron. Then for the clubs above the 5 iron, they will have to shift their thinking on set makeup to get a hybrid that is at least 3-4* lower in loft than the single length 5 iron, but which is at least 38″ to 39″ in length so they get the clubhead speed back that they lost from using the shorter single length for all the other irons.

      It’s nothing to worry about thinking that anything is “wrong” with the single length sets. When you make all the irons the same length to be able to gain consistency and identical swing feel, you have a trade off at the upper end of the set to possibly change your set makeup from what it was before unless you do have a higher than average clubhead speed.


    • Trey Farmigoni:

      Did you notice a difference in peak height between the sterling 4i and your conventional 4i?


      I didn’t hit the 4I; it’s not available yet. I hit the 5I, and a concern of mine is that it is both lower-flying and lower-spinning. But it also carried about 15 yards farther than my conventional 5I. I was swinging it at 88mph; I don’t anticipate trouble hitting the 4I. But….

      I’m very concerned about gapping, so I’m going to check carry distances very carefully on a monitor/simulator, then tweak lofts accordingly. Again, concerned about hitting them too low, too far, with too little spin. We’ll see.

  49. Any update on the 4I? When can I order one?

    • TONY

      It will be in stock by around Dec 10. You can order through Diamond Golf International who now handle all sales of Wishon Golf designs at 1-844-552-3437 (toll free) or at .

      Thank you,

  50. After several months with Sterling irons, I put them to the test in our club championship last week. I ended up with the lowest net score and third lowest gross – behind the state champion and a former pro who passed me by draining a hundred feet of putts in the last nine holes.

    All of my playing partners over the three day tournament remarked on the quality of my iron play.

    • MITCH

      Wow, that is great to hear that the new irons are performing so well for you !! Very tough to beat 100′ of putts in 9 holes, for sure !! Very well done and thanks so much for sharing this with us all !


  51. I too am a SL Sterling iron satisfied customer. I have been playing most of the season with mine (6-SW) and my HC has gone from 10.5 down to currently a 6.7. I too have had more rounds in the 70s than I have had over the last five years, including a 72, 74, 75 and 76. Prior to this year my low score was a 78 and I would usually shot 78 or a 79 2x a year, with other scores scattered in the 80s and 90s. I also went to slightly shorter shafts in my driver, 4w, and my two hybrids and my consistency has improved across the board. I am tall and I really like playing the sw, gw, and pw at an extended length. My sw is the highest lofted club I carry and I choke down on it for those 30-60 yard pitches. Overall I just like the simplicity of the idea, same stance, same swing plane, same weight, good results!

    • KEN
      Thanks very much for taking your time to visit and share your experiences with the new Sterling irons you have. That’s great to hear tht the difference has shown up in a definite improvement in score ! We’re so pleased we have had the chance to hear many experiences such as yours because it’s a big thrill to have created this new version of a single length set and then be able to sit back and hear how much the golfers like it.

      Thanks again and the very best to you in this great game !

    • Dear Tom,
      I already ordered a LH Sterling set to Arnaud Maurin in France, as soon as it will be available…
      Really looking forward !!!
      Thanks a lot for this.

    • Thank you very much Jean-Charles !! I’m not just pleased to hear that you may be one of the first to have a left hand set of the Sterling irons, but I am very happy to hear that you are working with Arnaud for your custom fitting needs ! He’s very good, and he is even more enthusiastic about being the very best clubfitter he can possibly be, so he can help golfers get the right equipment that will allow them to play to the best of their ability. I can tell you the left hand tooling dies are being made right now. That’s a bit of a longer process but we really hope to have the left hand heads ready to offer by middle Spring.

      Thanks again, and the very best to you in this great game !!


  52. Hi Tom,

    I eventually bought a set of Sterlings in September after quite a lot of thought. I had been playing the 560MC’s for about 5 years and was very happy, however the intrigue of the Sterlings took over. Sounds not unlike your story in a way!

    So how have they performed? Well, before I bought them, I was playing off 9 and a quick look at my scoring tells me that my average score this year up to then had been 79.9.

    I shot 82 the first time I used them, and since then my scores have been as follows: 76, 76, 77, 71, 78, 73, 77, 77, 76, 77. So just under 76 on average. My handicap has gone down to 7 (with a brief visit to 6!).

    Obviously it’s not all about the irons. I have been playing more golf than usual, and the rest of my game has probably tightened up. However I’ve definitely felt an improvement with my iron play.

    In terms of the subjective side, I would say that the most significant benefit for me is that the long irons are way easier to hit. I have found the 5, 6 and 7 quite a lot easier. I also love the sound of the high COR face. I want to call it a ‘ping’ but someone used that idea already :-). I considered the 5 hybrid but went for the 5 irons and my 85mph 5 iron speed seems to be plenty to cope with it.

    In terms of the other main benefit – one identical swing for all irons – for me this is secondary. One reason is that I have found that I tend to use a SLIGHTLY different swing for short and long irons, even with same length clubs. I put it a SHADE further forward and swing a little more ‘up’ with the long irons in order to maximise height/carry. Furthermore, I tend to find that I sometimes swing a little different if the shot calls for it (fade / draw / low / high etc). Over time I might find that I do indeed develop a single swing, but overall I think the benefit of “easier to hit long irons” is definitely the primary one.

    I have found the distance gapping to be pretty consistent compared to my old clubs. Bearing in mind that the Sterlings are roughly 1 club stronger, this is what I have found:

    Old Set Sterling
    4 hybrid= 175m 5i= 170m
    560MC 5i= 160m 6i= 160m
    560MC 6i= 150m 7i= 150m
    560MC 7i= 140m 8i= 140m
    560MC 8i= 130m 9i= 130m
    560MC 9i= 120m PW= 117m
    560MC PW= 110m GW= 105m

    In other words, the mid irons are roughly the same. My Sterling 5 iron probably goes a little shorter than my older 23 deg hybrid, however that hybrid is 3” longer so that makes sense. The Sterling GW is half a club shorter than my 560PW. But that’s fine now that I am used to it, it’s just really a question of getting used to your distances, as with any new clubs.

    Like some other customers have said, I found the PW and especially the GW (I didn’t buy a SW) a little harder to get used to. I think this was probably mental, as I probably knew that they didn’t go quite as far as my old clubs did, and was trying to hit it too hard. If I just hit them without over-thinking, they generally go fine.

    What I would say to people who may not get along with the long length PW and GW is that I think it would be perfectly fine to buy the 9 iron down to the 5 iron in Sterlings, and then use a conventional PW, GW. I think the 771 CSI PW and GW would blend in well. I know that this idea negates the benefit of one swing somewhat, but like I said, for me this was secondary to the benefit of having shorter long irons. It would probably be a very confusing concept to try and sell (“single length long irons then graduated short irons”), but it makes sense to me. If a customer was battling with the longer length PW and GW then I would certainly not rule that out as a solution.

    Anyway, all told I’m very happy with the new clubs. I’ve had quite a few comments on course, and know of at least one other person at my course in Cape Town who has bought a set.

    Thanks for another great job and I hope the Sterlings continue to do well for you.

  53. Tom,

    What is the difference between the Sterling Irons and the Cobra F7 One irons?


  54. I am wondering if anyone has had the experience of hitting the Sterling 5Hybrid farther than the 5iron. I was fit here in Wi. by one of wishon’s fitters/club makers on a Foresight GC2 w/ HMT launch monitor and the data showed the 5H carring about 12 yds farther than the 5i. My SS is 75 mph I was using the same steel shaft at 37″ club length and the same ball. This would be a good thing for me if it actually happens in the real world as it would fill a yardage gap nicely. So wondering if this has happened to anyone when hitting balls at the range or when playing.


    • Hi Dan: I have a similar swing speed and own both the 5i and the 5 hybrid. My set is 8 iron length and yours is 7 iron length. I hit the 5 hybrid consistently higher and further than the 5 iron. I think this demonstrates that for our swing speed, it’s hard to hit the 5 iron high enough to get the expected carry distance. A lot of club fitters decide where a person should use hybrids by finding where the gap just isn’t sufficient. For me, I hit the Wishon 6 iron about the same as the Wishon 5 iron. That’s why i stopped playing 5 iron and moved to the 5 hybrid.

    • Thanks very much for your input on this Harry. Without question, when the length of all the irons is the same and it is shorter than some of the lengths in a conventional set, the clubhead speed with the shorter length is going to be a little less than the clubhead speed with the longer lengths. In turn, that brings about a little less ball speed and spin which if enough, can act to prevent shots with the low loft irons from flying as high and as far. But you did the right thing in realizing that if you hit the 5 and 6 irons the same or very close to the same distance, that is an indication of what I just explained so there needs to be a move either to the little bit higher flying hybrid or even to just have the single length set stop at the 6 iron and go with conventional length hybrids above that. Thanks much !

  55. Hi, I’m really interested in these! Is there a fitter near Reno, NV (or northern CA) that you would recommend?

    • Michael:

      Thanks very much for your interest, we appreciate that very much. I am sorry to say that for unknown reasons, there are no clubfitters we can recommend in either the Reno or the Sacramento areas. The closest good fitters to you would be in the SF Bay area. If you do have a chance to travel to the Bay Area at some time in the future, please let us know and we can offer a very good recommendation for someone to work with to be custom fit. The other alternative is – this is a direct sales and direct fitting site created to offer golfers a custom fit set of the Sterling irons if they are not convenient to a clubfitter. We support this website by doing the fitting analysis from the questions posed for the golfers, and we do the custom builds on the sets so they are made accurately. This site also allows the player to input his own specs if in fact he is sure of what he wants. Thanks very much,


  56. I just unsubscribed from the blog “No Laying Up” due to their ignorant and closed minded assertion that Cobra is bringing out SL irons that “1,000s of golfers will be wasting their money and not improve their game!” For a sassy website that purports to be on the cutting edge, that is “establishment” thinking and criticism without even antecdotal foundation. Sassy but uninformed!

  57. Dear Tom,

    I must say, this set is TRUELY AMAZING.
    I am so satisfied with the sterling single length.
    i’m a customer from all the way here in Korea..(although i’m originally from california)
    thought I should share my experiences with single length iron tests and sterling set for potential buyers.

    i’ve been tryin to create my own set with regular irons (cutting down 5/6/7 to 8 irongs..used stronger lofted clubs on longer irons (TD rsi 1, etc) my old set looked like this.. 5/6/7/8 irons on all 36.5 inch length (with lead tape), 9/p/gap would be regular lengths (shorter and equal to 36 inch)

    downside to this was that for 5/6 cutting more than 1 inch resulted in distancing gapping issue..therefore i ended up swinging harder on my longer clubs (resulting in less accurate contact)

    and for shorter irons (9/p/gap): i’ve been practicing alot on 36.5 length lately, and fairly got good at it..but when I switched to shorter (36inch, 35.75, 35.5 inches for 9 and below irons)..I had really bad pull to left on these shots since my form and swing got so use to 36.5 (my upperbody angle, arm angles, swing plane..etc)
    it didn’t work out..also swing weight felt significantly different for 5/6 vs. 9/p since I couldn’t fully make up for the swing weight loss on longer irons due to cutting down)..

    so ended up purchasing sterling length:
    awesome, my swing speed and swing plane for 5/6 vs. 9/p/gap wedges were exactly the same.. and my directional issue has been solved since I was able to use the same swing speed and swing plane, same ball spot, stance.

    truely amazing. sincerely thank you to Tom Wishon from Korea.

    downside for me was the shipping cost and import duty…which was around 90 USD for shipping, and $250 for import duty!..but it is still worth it.

    also i’m feeling the short irons are not as forgiving as the leading game improvement irons from OEM. (distance loss on mishits)
    the mid/shorter irons seem more like the better player irons..
    maybe if this set goes success, you guys may consider making a super game improvement or game improvement sterling sets?

    also, i bought the 5 hybrid instead of iron, there is distance gap issue between 5 hybrid vs. 6 iron. (based on numerous test on trackman, my 5 hybrid distance is at 180meter ~ 190meter, my 6 iron is at 160meter~165meter..remaining clubs have distance gapping of average 10 meter all the way down to gap and sand wegde..maybe 5 iron would better suit me at my swing speed?

    but still, this set is definitely worth the money i spent, and i sold all my previous iron sets, and will only be using this set.
    my confidence and quality of my shot on irons have jumped up significantly..never had the thought of equipment = increase performance…but sterling set really did it for me.

    thank you once again.

    ps: i’ve customized my loft settings so i can utilize 56 degree wedge for short games. (only 50%~75% swing)

    9 iron at 39 degree
    p iron at 44 degree
    gap iron at 48 degree
    sand iron at 52 degree
    my own 56 degree wedge (taylor made atv)
    i wanted that 4 degree gap on shorter irons to be used for full swing shots..which is working great for me on distance gaps.

  58. Tom, I recently had the opportunity to work with one of the golf digest top 10 instructors in the US who I get to see a few times per year. We had some discussion about single length irons. He felt like an advantage of a traditional length set was that they would promote a steeper angle of attack for the shorter “short” irons where the club face first hits dimples lower on the ball, and a more shallow angle of attack for the longer “long” irons. I don’t think he had personally ever used single length clubs. Certainly, for me, there have been lots of gains in using a set of irons that allow me the same setup position and swing plane. Do you think there are any losses or downsides of having the same swing plane with all irons? I’m always interested in your thoughts. Regards, Harry

    • (Not Tom’s thoughts, but my own experience as a low single digit handicap who plays every day and coaches people of all abilities.)

      I have been playing Sterlings since they first came out and my own iron play has been getting better and better. There is absolutely no issue with ball flight on the shorter irons. My short irons – indeed all of them – are dramatically more accurate than before.

      I have made several sets for friends and they all say they love them.

      A couple of my friends are scary tall. I have been able to fit them well with Sterlings built to extra extra long, with lightweight shafts. Their posture and comfort is dramatically better. With conventional short irons they had to bend over so much that their back was in a dangerous configuration, and I couldn’t lengthen them enough without making them too heavy.

      Regarding the angle of attack: Maybe, just maybe, if you are an outstanding player with great flexibility and a perfectly repeatable swing, you might be able to benefit from a little more attack angle. But it is more likely, for everybody else, that a steeper attack will result in more fat shots. Ball position is extremely critical with a steep attack. Most players, even good ones, fight with getting the ball position right, and having different length irons compounds the problem.

  59. Dear Tom,

    Question on SWING WEIGHT:

    On your website, we have the possibility to choose the swing weight.

    The “Mens standard” swing weight indicated on your site is “D1” meaning that it would feels lighter in the head than my current D3.5 (TM Burner 2.0).

    Would I feel a big difference if I choose the “D1” swing weight rather than a “D3.5” ?

    Thank you and hope I can try my new set before the winter comes, LOL.



    • is not owned by Wishon Golf. It is an independent, direct sales website venture that simply sells the Sterling single length sets of irons to golfers. The head weight feel of a particular swingweight depends on the shaft weight. D1 with a very light shaft is not the same head weight feel as D1 with a much heavier weight shaft. Typically though, a club with a D3.5 swingweight will feel head heavy compare to a club with a D1 swingweight. Usually it would be enough that if you are above average in strength AND if you also have a more aggressive swing tempo, a D1 could feel too head light and could make you have some issues with controlling your tempo and timing and rhythm in the swing. But this is all based on the assumption that the D3.5 you have now is just right for your strength and tempo and never feels too head heavy at times when you play or practice.

  60. Hi Tom,

    Just wanted to confirm that you are still planning to introduce a lefties set of the same length irons as my custom fitter has informed me that currently it is not available to us lefties. If the lefties set is still in the works I want to wait to make those my irons.

    Keep up the great work.

    • Michael
      Yes, the left hand version of the Sterling single length irons will happen. The making of the tooling dies will commence very soon so we can try to release it in the spring.

      Thanks so much for your interest,

  61. I had assumed that with a traditional set makeup, half the distance gap between irons comes from the 1/2″ shaft length increments and the other half is the loft difference of 4 deg. So that in “theory” if a golfers iron distance gaps is 10 yards, then changing the loft of a single iron by 2 deg would result in a 2.5 yard difference.

    So I am intrigued that with the single length irons, the loft gaps are only 5 degrees, That suggests the distance gaps are affected by loft more than length?

    • MARK:

      In reality, 85% of the distance between any two irons comes from the loft difference on the head, 15% from the length difference. This was not known until around 15 yrs ago. This is why single length can work as a viable alternative to conventional lengths. BUT. . . there still is that 15% from length so this is why Sterling is designed with high COR faces in the low loft numbers but then can transition back to a carbon steel one piece construction for the higher loft irons to wedges.


  62. On the specs sheet does sole angle refer to bounce?

  63. Hi Tom.
    I’m writing from Poland!!! Yes Your SL Sterling Wishon set of clubs is present in this part of the Europe and i”m happy owner and user of them. They are awsome, user friendly, nice and smooth.
    simply “killers”….

  64. Single length irons keep gaining traction, here’s another article posted on yesterday: And their popularity will only continue to grow now that Bryson secured his Tour card for next year.

    By the way Tom, best of luck to you in your “new” endeavor! When I first heard the news I was devastated, until I learned that you would be staying on to help with the technical side of things. I just hope you know how much everyone in the fitting/clubmaking industry appreciate everything that you have brought to the table throughout your career – with the pinnacle (in my opinion) being your latest creation in the Sterling irons. They are truly a masterpiece in design and engineering. I played the 560MC irons since their inception, and even as a club fitter who has access to just about every other club component on the market and who is constantly trying/tinkering with different things, I never did find anything to knock those 560’s out of the bag – until the Sterlings arrived. After just two rounds with the Sterlings the 560’s went into the garage cabinet, and now I see these easily staying in my bag for another 8+ years. In fact, my ENTIRE bag is now Wishon (aside from the putter) – 919THI driver, 929HS 4W, 775HS 3-4 Hybrids, Sterling 5-PW+AW+SW+LW (SW bent to 60) – and I have never before in my life played all the same brand. But every one of your clubs have rightfully earned their spot in my bag, and they’re there for the long haul. I have a feeling they’ll have to pry them from my cold, dead hands when that day comes. 🙂

    • If I am not mistaken, they used the same heads in the test. We know that you can not make a SL set from Standard Heads and get the same results of a SL set of heads. I think the only valid comparison would be to do the test, head to head against Sterling Irons.

  65. Hello!

    I heard there is a 4 iron in the works…excited! Is it the same as the 5-7 in terms of materials used and the tech behind it or is it unique to the rest of the set because of the lower loft? What is the loft going to be?

    • Austin

      Yes, the final work on the 4 iron tooling and sample testing is done. We’re going to try to have inventory for the 4 iron to be ready to go in the late winter. It is the same construction and design as the #5, 6, 7 – 19* loft with the same HS 300 high strength steel thin face and carbon steel body. We are going to caution clubmakers and golfers to not use this iron unless the clubhead speed is over 80mph with the other Sterling irons because of the lower loft.

      Thanks much,

  66. Latest Golf Digest online equipment ‘zine has a good article about DeChambeau, single length club, and Sterling irons:

    Very good press!

    • THANK YOU ED !! Agreed, this was nice to read. Now I know why Stachura emailed me yesterday afternoon to ask a bunch of questions about single length irons.


  67. Bryson D wins at finals and gets his tour card with single length technology!!

    Let’s get those left handed sterlings out soon!!!

    • RALPH
      Yes I am sure he was VERY pleased and feels that a big load is off the shoulders with this win, and with it, getting his full PGA Tour card. Left hand version of Sterling will be done over the winter so we can intro it in the spring.

      Thanks much !!

  68. Love my irons. Played 18 holes right out of the box. No practice to get use to them. I hit the same them the distance or a touch longer than my Ping I custom irons. I can’t get the 4 iron in my bag soon enough. Tom, get me that 4 iron. Pretty Please!!!

    • DOUG

      Thanks very much for taking the time to share your experience with the new Sterling irons !! The testing on the 4 iron is done, we’re looking at around January for it to be in stock and ready to go. Left hand comes after that, lob wedge after that.

      Thanks again !

  69. Hi Tom, I have taken delivery of of my Stirling irons approx 3 weeks ago and find them amazing! They go slightly longer and just as high as my previous set,my consistency with my 6/5 irons is also much better. I am looking forward to the release of the *4 – will this be iron only or also in a hybrid?.
    Thanks again for all the hard work you have put into these

    • PHIL
      Thanks so much to YOU for your interest and for letting us know how well you like the new Sterling irons ! As the designer that is music to my ears to have the chance to know that you like the irons so much !! Final testing is done on the 4 iron and I would say we should have inventory around January or so, maybe February. It will be an iron, not a hybrid. reason being that the 4 iron is going to require a clubhead speed of over 80mph to properly elevate the shot at that shorter length and at that loft. So I figured those over 80mph are going to prefer an iron over a hybrid for a #4.

      Thanks very much !!

  70. Hi Tom, I am based in Switzerland but was able to get the single length irons, and I am super happy. I have the normal 5 iron and it goes around 187 yards consistently. However, especially with thicker grips, I start fading them sometimes too strong, but my body adjusted and I moved the ball back to the middle or slightly left of middle and it solves the problem.

    Is there a possibility to get a 4 iron/hybrid also? That would be helpful as there as all single hcp. players like me will have a gapping problem.

    cheers from Zurich

    • KLAUS

      We’re very pleased to hear that you like the new Sterling irons you have !! We will be introducing a #4 iron in the very late winter to early spring of 2017. Final tooling on the dies is about done, the early prototypes tested well, so it will be added to the Sterling set makeup.

      Thank you !

    • Hi Tom, that sounds great. Until that is available, what would you recommend to do to fill the gap?

    • Above the Sterling 5 iron, for now I would lean toward a #3 hybrid – a hybrid of say 20* loft built to be 38″ in length.

    • With my 75 MPH iron speed, I find that a 22 degree hybrid fits nicely above the Sterling 5. It’s half an inch longer than the Sterlings. I have a 19 degree hybrid too, but the gap between it and the Sterling 5 is too much.

      I’m eager to try the Sterling 4 even though my swing speed may be a bit low for it.

      More Sterling kudos: Yesterday someone was telling me about Bryson D’s win, remarking how easy BD made it look, and asking about my Sterlings. He then told me about some Callaways that he liked, which use game improvement tech in the longer irons and solid backs in the shorter ones. I said “like this?”, showing him the Sterlings and telling him that Tom is arguably the best designer on the planet. He tried one and remarked on how good it looked and felt. The comment about the looks was especially nice considering that he is currently playing with Mizunos that are drop-dead gorgeous. I’m building him a test club now. I predict that he will have Sterling in his bag soon…

  71. I love my Sterling irons. I’m hitting more greens than ever, just firing at the pins. Hitting 12 to 14 greens in regulation used to be outstanding for me, now it is ordinary.

    Initially I didn’t care much for the Sterling SW, but recently I have warmed up to it and it has earned its place in my bag. I’m hitting all of my irons about 7 yards longer than my previous set; the SW fills in nicely for the just-under 100 distance. I don’t really use it from sand, but rather as a “gap gap” wedge.

    It is so nice not to worry about different ball positions or swing tempos for different irons. My practice time is more effective, as practicing with any iron is like practicing with them all.

    I have built three additional Sterling sets for friends. One of them loves the Sterling 5I so much that he often tees off with it, preferring to hit 5I + 5I on tight par 4s, versus getting in trouble with a longer tee shot.

  72. Dear Tom, As a retired teaching pro emeritus I remain interested in great challenges and improvements upon the old paradigms. Certainly we still enjoy retro play with hickory clubs, great fun. (Gives one a true appreciation of the skill sets of Bobby Jones, and we get to wear Plus 4s.)

    No need to mention the revolution that happened when Byron Nelson took up steel shafted clubs, to follow later metal woods, rechristened fairway metals, Karsten Ping’s innovations in cast clubs, the list goes on as we golfers know.

    There are myriad theories of how to swing a golf club, and Ernest Jones
    (c. Post WWI) argued you don’t understand what swing means- going to and fro, and most golfers don’t have one. Yet, we in the teaching industry try to answer the eternal question, “what am I doing wrong?” when, in my opinion, we should look more at “what’s right” or “what can I give you that will help you discover how to do this to your best ability?”

    I have to give you a four star “kudos” for your work at Wishon and the design of the NEW Sterling Irons. Years ago the concept of a single length clubs arose, then a single club with adjustments for all lofts, just turn the dial, and even one that shoots the ball forward with a press of the button. Don’t see those raising any excitement because besides having “a novel” idea there were foibles that were not accounted for and they didn’t work for what we are looking for, to use the trite phrase “a better (golf) mousetrap”.

    If I were to ask for the best thing I would want for my clients I would question: how can we perfectly match a set of irons, give them a feel that is the same throughout, make them forgiving, fun to use, and be an advantage over their current set that let’s them use an identical full swing for every club, short finesse shots and putts notwithstanding. In a less eloquent way, have I not just described your Sterling beauties.

    If I could get a client who is willing to have an open mind and can appreciate the physics, mechanics, kinesthetics, trained subconscious, neurological aspects of maximal performance, mind-set and psychology, I would say get a custom fitted set of clubs that allows you to learn and feel your personal one swing, the same every time, that you can use for all full golf shots. THAT’S WHAT YOU’VE CREATED IN THESE STERLING IRONS.

    Yes, I know, it doesn’t mean we’ll/they’ll be able to do it, BUT with your concept of clubs, in my limited knowledge and experience, for right now they finally have a tool to do it with! Even if they remain club golfers with a typical round of 90-100+, they will have a set that will more easily get them towards 80 and downwards.

    When I discovered Moe Norman I had a handicap of 23, in one year I got to a 9. His changing paradigm that went against everyone else on The Tour was a method to understand Single Plane. When Bryson DeChambeau did so well in The Masters after winning the National Am people noticed. What the *#+* was that? I call it a paradigm challenge of major significance.

    You, Tom, have made a club innovation that is the paradigm changer that will enable golfers to get better quicker and have more fun. And, even better, you don’t have to be Moe or Bryson with their personal style to do it. It works well with any swing methodology. Well done. Thank you.

    Since building my Sterling set I now have my handicap down to 3- old, fat, and bald, ha, ha, ha. (I prefer aged to a finer patina, appreciative of a great meal and a nap, and in need of fewer haircuts.)

    Keep up the great work. You are a gem.

  73. Hi Tom,
    I finally took the plunge and had Ken C. (In AZ) fit and start to build me a set of irons. We started with the 5i, 8i, and GW. Great clubs! Ken does a great job! Anyway, I noticed in the comments section that you now are bagging the Sterling irons and I had a question. Did it take you sometime to mentally get use to the change for the 5,6,&7. The clubs performed really really well when I just made my normal swing but I did struggle some with trying to go after the shot. I think my subconscious mind was saying you have to hit this 5i hard cause it is shorter. Funny thing, when I swung it like a normal “8i”…it went “far n tru”…so I urge other players that may experience the same thing to give it time and stick with it as your mind will adjust. I am not completely there myself but boy these are great clubs and allot if fun to play!

    there yet Thanks again for designing such a fun set

    • TJ

      Thanks much for taking the time to come to our site and share your experience in being fit for a set of the single length irons. I have known Ken Christopherson for a good while in this side of the business and he is good at it and has very good knowledge and experience now to help golfers as he has with you.

      I went through my personal “bout of weirdness” with the lower loft irons during the testing phase and so too did a number of the hit testing group. It was enough that I did identify this as a possible starting obstacle to have to recognize among some golfers. But in time, it wears off as you hit more and more shots. So at this point, I don’t personally even think about the lower loft irons being that short. It’s normal to me now.

      Thank you much !!

  74. Hi Tom

    I am quite close to pulling the trigger on a set of these now. Most of the questions that I had in mind have now been answered by now, but there are just two more.

    1. My 5 iron swing speed is 80-85mph. I carry it +/-170-175 yards (it’s a 560MC @27 deg loft). My swing speed has stayed constant over the last few years, but I’m almost 50 now and it will no doubt drop from this point forward. The question is this: do you think it would be more advisable to go with the 5 hybrid rather than the 5 iron? I can get a normal 23 or 24 deg 4 iron airborne ok, but am concerned that I won’t be able to get it up (if you’ll pardon the expression) with a 5 iron at 8 iron length. And if I can do it now, I won’t be able to in a few years. What would you advise there?

    2. After my 5 iron, I play a 4 iron (or sometimes a 4 hybrid) at 23 degs. My next club is then an 18 deg 5 wood. The distance gap between the two is probably a bit more than ideal, but it’s ok. However, if I change to the Sterlings, is it likely to give an even bigger gap? I suppose another way of asking this is: would there be an APPRECIABLE difference in distance between a 38″ 4 iron / hybrid versus a 36.5″ Sterling 5 iron / hybrid, with the same loft of 23 degs for a 5 iron swing speed of about 85mph?

    Testing the clubs would establish the answers I am sure, but I will only be able to demo a 6 and 9 iron.

    Oh and one final thing. I’d have the Sterling built with steel shafts in R flex. Should the 5 hybrid get built with the same shaft, should it be graphite or can it be either?

    thanks so much once again

    • Frazer:
      I would recommend you skip the #5 in total from the Sterling set – not in an iron or in the hybrid. You are definitely at a high enough speed to hit either one of the 5’s in this set right now. But as you said, you have a concern that when you start to lose some speed, the #5’s would be more difficult to get well up in the air to fly. I’d go #6 to SW and then see what your usual carry distance with the #6 is. Then look at your 4 iron to see if that fits the bill to be the next club up from the #6 Sterling iron. Another possible is a 23-24* hybrid at around 38″ to 39″ in length. Such a club as well might fill in a bit of that gap you have to the 5 wood.

      You want to always keep the same shaft with the same trim in all the single length clubs. Other wise you deviate from the duplicate swing feel for each club, which is a big part of the benefits of single length to begin with.


  75. are there any distributors in the UK for the Stirling Iron set. I am seriously considering moving to this set up as i have trouble with consistancy with the longer irons.

    • Paul
      Thank you very much for your interest. All of the Wishon Golf designs are available in custom fit, custom built form only through independent custom clubmakers. There are quite a few clubmakers in the UK who could work with you in the fitting of a set of Sterling irons. We maintain a listing of the clubmakers through our FIND A CLUBFITTER search tool on our website. If you head to this link for the search locator, you can input your town and country and the locator will list all the clubmakers in order of distance from your location.

      Thanks very much,

  76. Dear Tom,

    I would like to personally thank you and your team for all your time and hard work on the Sterling Iron project. I got my Sterlings (5H – GW) in May, with UST Recoil Shafts in them. I am 55 years old and play to about a 12-15 handicap. I have played golf since I was 32, and was a Mizuno guy all the way. I have always been a person who thought outside the box, and tried new things. When Bryson Dechambeau hit the scene I was very interested in his clubs. I even wound up playing an Edel putter. After a lot of research I found you and your company. I went and was fitted for the Sterlings and was amazed at how – after just 10-15 minutes of hitting the irons, I was not at all focused on the length of the club, but on the feel of the club. I have really enjoyed the clubs and have shared them with someone new every time I go to the driving range. I love to hand them my 6 Iron, and watch them hit it really long. When I explain the concept to people, most of them say, “it makes sense to me!!” This summer my 16 year old son played in 8 tournaments. Four of those he played his OEM irons, and the other 4 he played my Sterling Irons. We saw a great improvement in Greens hit, and he said he loved the look and the way the club got through the turf. We are preparing to get him fitted for a set of Sterling Irons. Maybe we will be the first Father Son Duo for Sterling Irons !! Neither I, or my son saw any distance problems or gaps in our play of the Sterling Irons. I would also like to say Thank You to Your staff, every time I call, they are so pleasant and informative, and they act like they have all day to talk with me. I am planning now to be fitted to your Driver, and Fairway Woods, and Hybrids. I urge all of you golfers out there who are not traditionalist, to give the Sterling Irons a try. I think you will find, as we did, that being in one position for all your irons, is so much more comfortable, and the feel of all your irons being the same is indescribable. Thank you for Blessing Us with a great Product, and for never being satisfied with the limits of what Golf Club Making can be for all of us who love this great game.


    • BARRY

      Thank you SO MUCH for taking the time to share your experience and very nice comments !! How nice is that to know that you may very well be the first father/son playing duo to be using the Sterling irons !! (Cuz I have yet to convince my son – he’s very hard headed at times!! HA!) What a pleasure it is for me to be able to hear that you and your son like the difference in the irons and that you are both enjoying the game a little more because of it. Makes my day !!!

      Thanks so much and the very best to you in this great game!

  77. I am very interested in your same length Irons. My problem is I’m retired Military and living on a fixed income. If you have any demo sets at a reduced price that will be available in the future I will be very Interested. Thank you Bruce Barton…

  78. Hi Tom

    I have been playing your clubs for a few years and love them (I’ve even converted a few other golfers to TWGT).

    I was intrigued by the single length concept even before the Sterlings, but now with the way you and Jaacob have done them, it REALLY makes sense and I am keen. There is just one question you may be able to answer.

    In your comparison of your distances with 560’s vs Sterling showed that the Sterlings play more or less one club longer. That makes sense, as the 560MC 7 iron is the same loft as the Sterling 8 iron. It’s not exact, but it’s near enough for me.

    So I am comfortable replacing my current 560’s with the Sterlings on the basis that the Sterlings are more or less a club longer.

    The question arises when we get to the Gap Wedge.If I compare the two sets, I find that (comparing loft alone) the sets diverge a little as we reach the shorter clubs. The 560 PW is 47.5* vs the Sterling GW at 50*. My existing GW is 50*.

    I’d like to to keep my GW (and the other wedges), but I’m not sure if I would end up with “overlapping” clubs if I also bought the Sterling GW?

    My options seem to be either to keep my existing GW-LW and then (a) go with Sterlings in 5i-PW (and have potentially big gap from PW to my old GW), OR (b) go with 5i-GW (and have a potentially small gap).

    I suppose another way to ask the question is this: do you find that you hit your Sterling GW as far as your 560MC PW, or are they quite far apart?

    What would you do? I know the real answer is to test them, but the fitters where I live will only have a 6 and 9 iron, so that won’t really answer that specific question.


    • FRAZER:

      Thanks so much for your continued support !! We really do appreciate it. I should probably clarify in more detail my own experience with distances of my former 560MC iron set vs the Sterlings. The distance differences are not the exact same per each head number because the lengths of the 560 were conventional while the length of the Sterling is constant. Starting at the bottom end of the set, my Sterling GW at 50* is about 10 yds longer than my 560-AW which was an inch shorter and 52* loft. Sterling PW is about a half club longer than my 560MC PW. Sterling 9 iron is about 3/4 club longer than my old 560-9. Sterling 8 iron is a full club longer than my 560-8 iron. Sterling 7 iron is a full club longer than my 560-7 iron. Sterling 6 iron is about 3/4 club longer than my old 560-6 iron. I did not use a 560-5 iron in my old set makeup – I had a 775HS hybrid #5 in its place.

      And I have kept that old 775-5 hybrid because my 78mph clubhead speed and 8 hdcp (ouch, age hurts !!) is not enough for me to effectively elevate the Sterling #5 iron at its 23* loft and at the 36.75″ length I play the Sterling irons at. I did originally keep my HM series Sand Wedge which is 35.25″ in length. But I saw a bigger gap between it and my Sterling GW so I am about to move into a Sterling SW at my single length of 36.75″ to cut that down. We’ll see how that goes.

      Perhaps this helps you a little more as you analyze your set makeup and loft needs.

    • Hi Tom

      Thanks, that does help a lot.

      I’ll try out the demos next week which should tell me more. But in theory at least, it seems like I could keep my current GW-LW, which would also give me the benefit of 3 similar clubs that I use mainly for short shots.

      I also had a look at the clubs in the flesh today. Very pretty. The 5 hybrid looks easy on the eye, so if I do take the plunge I will probably go that route rather than the 5 iron (I hear you loud and clear regarding the age thing!)


  79. Congrats on Sterling Irons being recognized in this Months Golf Digest. Hope that brings more golfers into the Sterling fold.
    I have mine for about 4 months now and they WORK.
    Fred Meyer

    • Thanks Fred, we’ll see. I should know by now that when they contact me and ask for samples to shoot and tell me they are going to run a story on a model of mine, what they should say is that they’ll show it with 5 others and use a grand total of 15 words about the model. But HEY! Any notice is better than no notice !!! Better than the publicity is hearing that you like the clubs !!!


  80. Wow, this is great exposure – was totally surprised to see this in Golf Digest – I grabbed my fitters test club (with a way too light shaft and hit them this week) and loved the same swing between the 9 and 5 iron. Will have to go and spend some time with these. Congrats Tom!

    • Thanks for the head’s up on that. It was months ago that they asked us to send in samples for photography and telling us it was for the Sept issue. They work 3 months ahead of issue date so I had forgotten this was coming. Thanks for letting us know and sending the link.

  81. I picked up my new set of Sterling irons and have played my first 3 rounds while on vacation. Once I got dialed in on the course and the weather was normal I definitely felt a marked improvement in my shot making. In the third round I shot one of the best rounds of my career! The irons have been able to get me on or close to the greens and allow me to accomplish better finishes on most holes. I shot par on 8 holes in the round. I think previously I might have had 3 or 4 at most in a round. I had maybe 3 holes that I “blew up” on that accounted for 6 strokes I should have not needed. Had I been able to keep those to bogey’s it would have been an 11 over round! All in all these clubs are very impressive. My fitter chose to go with a XP 95 True Temper shaft and it really fits my tempo and speed. Great product and solid design. Thanks also to my clubfitter for all the custom evaluation and tuning to truly get these irons to maximize my opportunity to play well.

    • Thanks so much for sharing your experience with the new Sterling irons with us and everyone else ! We’re very pleased to hear that your results are positive and that you can see and feel the difference that a single length concept can do ! Best wishes for more enjoyment in this great game !!

  82. Tom – Since these are .370 bores, I was considering having a set shafted for my daughter with KBS 560 Shafts. Do you have any guidance that I can pass on to the fitter? Driving distance with a 39″ driver is about 170-180.

    • TRAVIS
      I don’t see the Sterling irons as being the right fitting solution for a junior player or for players who have much slower swing speeds. Not until the golfer has a clubhead speed in the area of 70-75 mph or higher. And even then, you have to be careful not to give the player the most low loft irons in the set makeup. When you make all irons a shorter single length as we do in the Sterling set, that shorter length brings less clubhead speed than if they had longer lengths in the irons. The slower speeds make it more difficult to get any lower loft head to fly high and stay in the air long enough to carry a full distance. So we see a 5 iron swing speed requirement of 75mph as necessary for a Sterling set of #6 to SW, and over 80mph to be properly fit into a full set of #5 to SW. Down at 60-65mph, you would not want to have a 5 or 6 iron in the set. And then the other clubs would be high loft woods or hybrids made to more conventional lengths to fit the player.


  83. Tom – What clubs do you recommend for completing as set of sterling irons (Driver, fairway metals, 3 and 4 irons)? Would these clubs be the same lengths as the irons? If not, how much longer would each club be?

    • DOUG
      Thanks much for your interest for sure. Whether you have a 5 iron or hybrid in the Sterling set depends on your clubhead speed. With the #5 being 23* loft at 36.5″ or 37″, you’ll need a clubhead speed with the iron of at least 75mph or more to adequately elevate that low of a loft even with the high COR face to be able to get it well up to fly the full and proper distance to deliver a proper distance gap up from the #6. If so, then the club above that should likely be a 23-24* loft hybrid at a length of around 38 to not more than 38.5. Above that can come at your preference either a 20-21* loft hybrid at around 38.5 to not more than 39, OR if you prefer woods, a 20-21* #7 wood at not more than 40″. Above that depends on your clubhead speed and ability. Some may go 17* 4 wood at 41-42″ and then a driver fit separately and normally but hopefully not longer than 44″. Or some may go 18* 5 wood at 40-41″ and then a 42-42.5* #3 wood if they have the clubhead speed and ability to properly elevate a 3 wood to make it fly and carry well.

      hope this helps,

    • Hi Tom:

      I have made left handed single length sets using your wedges, 979ss high lofted iirons, and 771csi irons in the low lofted heads. For those that can’t wait till next year for a left handed set of Sterling irons they might want to explore this option.

  84. Hi Tom,
    So excited for the LH version.
    You’ll sell 3 sets in my household immediately.
    It is so hard to get anything “custom” for LH individuals, I know I’m not the only one excited!

    • Thank you Josh, interest is noted for sure, and I think this is probably going to head toward an early spring release of the left hand version.


    • 🙂
      Great news for all lefties out there

    • extremely excited for left handed version!!!! already got the check ready

    • Thank you and we will certainly do our best to hurry this decision along to add the LH version of the Sterling irons !!!

    • Looked forward to the lh version as well!

    • I asked Tom about left handed clubs a little while ago but they were not on the table then. So I am also really interested if LH Sterling clubs are coming soon.

      I had an iron set from 1IronGolf quite a few years ago but they did not really work out very well and they are not truly custom fit, just fit to certain measurements given via email.
      I hope Tom will keep a list of interested golfers and send out an email when they are available..

      Thanks very much for your continued interest in the Sterling irons. yes, we will be doing these in left hand with an eye toward a spring 2017 release. We’ll do our best to let everyone know who has expressed an interest!


  85. Tom,

    I’ve been looking at the Sterling iron set and comparing lofts to my current irons(similar to your 575 lofts). I have 5 clubs 31* to 46* that cover 100 to 150 yds. Sterling has 4 clubs to cover that distance. I like gaining a club to put in the bag but I’m concerned that it makes each club less precise. What were thoughts on removing one club from that range?

    Ed Smith

    • ED:
      Thanks much for your interest and I’m always happy to help with the best information. if those lofts are dead on right and not +/-1 to what you think they are, then you are looking at around a 10 yd gap between each iron from 100 to 150. By our modeling calculations, this means your clubhead speed with your 31* iron is 73mph and with the 46* wedge it would be 65 mph. Those are not super high speeds so a 4* loft gap between irons will be down there in the realm of 10 yds. With Sterling, more than likely you’d hit the 31, 35, 40, 45 irons with around a 12-13 yard gap between irons. 6 to 9 feet in other words. Not very much difference. And none of that has anything to do with precision.

      The precision part has to do with the fact that a single length set means that every iron has precisely the same swing feel. Every possible element that has any effect from minor to major on swing feel is identical in each iron because single length means the shaft weight, total weight, swingweight, shaft flex, MOI and balance point of every club is identical. Right now in any conventional set, only swingweight is matched. Every other one of these feel related elements is different in each club in a conventional set of irons.

      Then you have the part of single length where because each iron is the same length and lie, your set up is the same for each iron – same stance, posture, spine angle, ball position and swing plane. That adds to the identical swing feel to offer a darn good chance at a higher level of shot consistency, swing repeatability than what a conventional incremental length set can do. So the realm of possible precision leans in the favor of the single length for these reasons above.

      The reason I went with 5* loft gaps on the Sterling is because this is one way we achieve proper distance gaps between irons when the lengths are all identical. When lengths are the same, clubhead speed is the same with each iron. With incremental length irons, clubhead speed increases very slightly and progressively as the lengths get longer up through the set. So to create proper distance gaps in the mid and lower loft irons, a 5* loft difference was called for. But in the lower loft irons in the single length set, we can use 4* gaps because the HIGH COR face design of the 5, 6, 7 allows for a higher launch angle with more ball speed.

      Hope this helps, thanks for your question.


  86. Tom,
    I played my first round today with my,Sterlings. I was fit for 37 inches and a bit skeptical going in as I usually play a 37.5 7 iron. I went with your Stepless Steel in stiff, mid size and 3 up. I’ve got to say I am very impressed after my first round and a practice session. The irons look great and the top line is relatively thin which pleases my eye. The feel is excellent-very soft particularly the 8-SW. Distance and trajectory are excellent and the 5, 6 and 7 high core face really gets the ball out there. Love the feel of the shafts. One of the things that blew me away was the gap and Sand Wedges. Really easy to hit a variety of shots including a flop if you open up the SW. I made better contact with the shorter shafts than my traditional irons. All and all very impressed and I am sure it will get better as I gain more experience.

    • MIKE:
      Thanks for letting us know how it’s going with the new irons. We’re pleased to hear that the irons are off to a good start for you, and especially with the wedges. That right there is one of the main reasons we chose to go with the shorter 36.5″ length and then work very hard on the face design to bring about proper distance with the 5, 6, and 7 irons.

  87. Tom, I could not figure out how to reply to your specific post. I asked about 37.5 inch sterling setup. Swing weight will not be an issue. However, this does bring in a shaft selection question. On your shaft fitting system I am Driver 110MPH Transition 3 release position 3. Iron 90MPH downwsing tempo 2 to 3, physical strength 3. An S2S stepless Iron S wihta .5 tip was recomended. Is this selection applicable for the Sterling system. Also, if i want to start at 37.5 and want the option to butt trim down to 37 if needed, would the shaft selection still apply. Finally, with shorter long irons longer short irons, how does this relate to where i would want to trim the saft… how does this effect tipping the shaft if any. I will often take a 3/4 swing with 8-SW but tend to take full swings with 4-7. Thanks

    • NICK

      If you are set on the 37.5″ length, and with you actual being 90mph with a conventional mid iron clubhead speed, then I would do a 3.5″ tip trim the Stepless S – a little more for the 90mph being above average for an S player, and a little more as well for it being 37.5″ with a higher than normal swingweight. ALL the shafts will be tip trimmed the same because ALL the irons would be made to be 37.5″.


  88. Tom,

    I am interested in these Irons. I have a single plane (moe norman style) swing and I use a 10 fingered grip. With the grip, my right hand is a little lower than it normally is with a standard vardon grip. This creates a choking down effect and lower hinge point reducing leverage and distance. I hit a set of Nakashima clubs that are 1.5 inch over standard length on all clubs for my single plane swing. This creates a heavy 4 iron as you can imagine. I feel I could benefit from the single length irons. However, I feel they would need to be at least 1 inch over your 36.5 set length. Can you make this set to 37.5 inches while still balancing swing weight? in standard length irons i typically play a 5.5 – 6.0 for irons. Standard 6 irons swing speed is 90-95 mph. Driver is 110.

    Let me know.

    • NICK
      Take a moment to think about this . . . . in your +1.5″ overlength set, your PW is 37″ and I imagine you are fine with that length and it is not uncomfortable for you to set up to the ball and hit shots. As such it stands to reason that a Sterling set at 37″ should be comfortable enough for you. And with a 90mph iron speed, you would have zero problems achieving proper distances or trajectories with the Sterling irons.

      It’s your call in the end though. Just understand that at 37.5″ length, the swingweights would be above normal and result in a head heavy feel for the clubs because the head weights of the Sterling irons are designed for normal swingweights at 36.5 to 37″. But then too you probably are used to a higher than normal head weight feel if you have been playing +1.5″ irons, so this might not be a problem for you.

      Hope this helps,

  89. Tom would you ever consider fitting a high ss player with 3 degree loft gaps in wedges? For example going 50,53,56,59? Or would that be over kill. I don’t ever carry a 3 wood because I’m just as accurate with driver and I hit my 20 degree hybrid 275. I tend to be in the 100-65 range on approach shots and wondered if 3 degree gaps in wedges would close the gaps down better. Have you ever seen this done?

    • Kourt

      Never seen it done personally but it certainly could be done for high speed players. No question the higher the speed, the more distance gap will be that comes from smaller loft gaps between clubs. Now this always assumes a full swing speed for each club to do that. With wedges there will be many times when you swing less than full with at least some of the wedges – SW and LW in particular. So with those shots the player might have some getting used to in order to predict what swing length and force hits the ball what distance. but it certainly can be done if there is room in the bag to do it.


  90. More feedback on my Sterling irons. This weekend I was paired with a club pro for a quick 9. I was talking to him about my single length set, and I could tell his reaction was “cheap junk gimmick”. He was a tremendous ball striker and clearly an accomplished pro. Hole by hole, as I hit one baby draw after another he started to become intrigued. He pulled one out of my bag and took a closer look. He said, they seem to have a nice sound coming off the ball.
    We came to a Par 3 185, so I said let’s do a little experiment. Hit your normal club then hit the equivalent Sterling. He was using a Titleist Players iron set, not a blade. He hit his six and seven, then hit the six and seven from the Stealing set. He said wow these have tremendous feel, and higher ball flight. We approached the green and he had hit the six over the green as expected, and there was the Sterling ball he hit just 3 feet from his Titleist. The two 7 irons were both on the green and also within a yard of each other.
    Tom you’ve nailed the yardage gap issue with these it just doesn’t exist. His and my distances are near identical to standard OEM irons, and feel is off the charts good. All I can say is you’re on to something here……….

    • TOM

      May I say your story of the encounter with the doubting club pro brought a very wry smile to my face !!!! Kudos to him though for having an open mind to see what you have found with the new Sterling irons !!! VERY well done !!

      TOM ;>)

  91. I have a question about design principles when it comes to the #5 hybrid integrating into the rest of the set. I understand why you went with a little bit more offset on the lower-lofted irons, to help achieve the proper trajectory with a slower clubhead speed compared to a traditional length iron. But that being the case, why wouldn’t the #5 hybrid be designed more like the 335HL with less FP (7mm) rather than the 775HS which has 16mm of FP? That makes a 19.5mm difference in the leading edge position of the #5 hybrid compared to the #6 iron, whereas the 335HL head would only have a 10.5mm difference. I tried the #5 hybrid and I found I was pushing everything straight to the right with it, and I needed to put the ball a little further forward in my stance to prevent that from happening, and then I hit everything thin and low. So I guess back to my original question, what was the reasoning for going with a #5 hybrid that has such a drastic difference in offset compared to the next club in the set?

    • James
      I was following the design of our very popular model 775HS hybrids in doing the design of the Sterling 5 hybrid. And in hit testing with the focus groups, we just did not see the shot shape difference you are experiencing. Otherwise it probably would have come to me to change that.


    • After posting this yesterday I had a lightbulb moment and realized what the problem is, and it’s that I’m a completely idiot. I have my entire set bent to 68° (which I bent myself), but when I ordered the hybrid I forgot to request that it be pre-bent to 68° since I don’t have a bending machine that can do hybrids. That would explain my dead pushes to the right with that club compared to the rest! I thought it was odd because I also have the 3 & 4 775HS hybrids in my bag and I hit those great (although I do play them a lot further forward in my stance), so I was shocked that I wasn’t hitting this one well since it’s virtually the same head. Guess I’ll need to find somewhere to get this bent!

      I still think a head with a little less FP would integrate better into this set, maybe even one an offset similar to the #5 iron (like the Ping G20 hybrid design). That would be one more thing to add to the sameness of the heads in the SL set.

      While we’re on the topic, why is it that nearly all hybrids on the market have forward face progression rather than offset like the irons? Is it done due to some sort of design principle, or is it just easier to make it that way?

    • JAMES

      In the task of head design there are things that look different that really do not matter on performance, and there are things that you have to be aware that a majority of golfers don’t like and won’t buy the club if those things are a part of the club’s design. most golfers prefer some face progression on hybrids and will reject those with offset more like an iron. it just happens this is an esoteric “looks thing” with many golfers. So that’s one very good reason not to make a hybrid with the leading edge behind the forward wall of the hosel. Second, differences in FP are insignificant to performance for 98% of all golfers.

      So that’s the best answer I can give you,

  92. I am very interested in this set. I recently bought the following Ping G set:
    Yellow dot, standard length, gold grip, graphite SR flex (Irons: 6,7,8,9,P,S,L (58 degree))
    What setup of sterling irons do you suggest?
    Thanks in advance
    Kind regards

    • JAN

      If standard length on the G set means a 36.5″ #8 iron, then the same things should be done on the Sterling set. Yellow dot in the PING vernacular means +1.5* upright, Gold grip means +1/32″ oversize. We do not know the exact specs of this Graphite SR flex shaft, but if you visit a custom clubmaker to be fit to get the irons, the clubmaker should be able to analyze your clubhead speed, tempo, point of release and determine a similar or suitable shaft to fit you. To find a custom clubmaker to work with on this, please head to this link on our website to input your location to see the clubmakers closest to your location –

      Thanks very much for your interest,

  93. I just got my shipment of a set of all the heads and I am going to build a test set for my customers. I am wondering if most builders are shafting the 5 hybrid with the same steel shaft as the irons OR using a graphite shaft?

    • GLEN
      Regardless of whether the set includes the 5 hybrid or 5 iron, ALL the clubs get the same iron shaft, tip trimmed the same way. The only difference in the hybrid vs iron is that we tried to make the hybrid have a lower and more rear located center of gravity so if the golfer were on the cusp of not having a high enough swing speed to effectively elevate the 5 iron to get full proper carry distance, then he could opt for the 5 hybrid and perhaps get a little help in this. To break away to use a different shaft type or weight means you break from having every single club in the Sterling set have precisely the same swing feel so you could affect the overall goal of improved shot consistency from all the clubs in the Sterling set.

    • Thank you for the response. What about taller players. Say someone with wrist to floor of 39″. Would you still build at a max of 37″. The person I am fitting current 8 iron length is 37.5″

    • GLEN

      If at all possible I would keep the length not more than 37. Think of it this way – in this man’s set, his 9 iron is 37″ and he must feel that it fits him for length just fine. What you have to go on more is the golfer comfort when you work with tall people with greater wrist to floor measurements. Find the shortest length at which they can set up to the ball and be comfortable, and not feel like they have to bend over or crouch down too much. But if he is in the slightest way uncomfortable over the ball at 37″, then move it up. Normally you do not want to go over 37 because that does two bad things that most golfers won;t be used to – 1) it will push the swingweight up very high, higher than what they may have in their normal irons, 2) it will make the wedges much longer than they are in a std set which can cause accuracy and distance cpntrol problems.

      For this man with a 37.5″ #8 iron length in his normal set, probably those irons are high in swingweight because they probably were std irons that were lengthened. So it may work out at 37.5″ for him. But do as I said and only go longer to 37.5 if he feels he has to bend over or crouch down more at 37″.


  94. Having built a few sets of Sterlings, with each set needing lie adjustments, I have noticed that the 5-7 irons are much harder to bend than the 8-SW? Why is that? Don’t the high-COR irons have the same 8620 carbon body as the rest of the irons, meaning the hosel of each is made of the same material and therefore should bend the same?

    • James

      Yes, and happy to explain. The high strength steel face of the #5, 6, 7 has to be heat treated after production to bring the face alloy up to the proper yield strength to maintain proper durability for its “thin-ness” while also keeping the strength where it has to be for its thin-ness to achieve the proper high COR performance. You cannot heat treat only the face since the whole head goes into the heat treat ovens. So the heat treatment stiffens up the carbon steel body as a side effect. But on the #8 to SW, since they are a 1 piece construction totally made from the 8620 carbon steel, they do not need that heat treatment so they end up with a higher level of ductility which allows them to be bent more. It’s a product of having two different head constructions within the same set, which is something that has never been done before in iron design to my knowledge.


    • Ah, that makes sense and clears up a giant ? mark that I head in my head about these clubs. It sure had me confused! As I was bending the 5-7 irons on the first set, I was thinking to myself how they felt much harder than I was expecting – having bent many carbon heads in the past – and it seemed almost if they were made of 431SS. I had a hard time getting them to 4° flat, but I did eventually get there. Then I put the 8-iron in the bending machine, and I applied the same amount of force that I had been using on the others and it went WAY past 4° on the first push! LOL. I had to bend it a few degrees back up to get it to 4° flat. And then I noticed the 9-SW were all easier to bend as well. I thought it was maybe just an anomaly, then on the next set I noticed the 5-7 were again harder to bend…but at least I knew what to expect once I got to the 8 iron. 🙂

      Thanks for the reply and explanation!

  95. Hi Tom
    Thank you for your quick responses thus far.
    I am not sure if this has been covered in the previous comments (alot to read through) but in the meantime of waiting for the Sterlings to be released in LH, could my current irons be “converted”?
    I have Mizuno MP-54 standard lie and length.

    Many thanks

    • Jim:

      No, not without one heckuva lot of hard work which in the end would make some of the clubheads look horrible. Here’s why. Let’s say you did want to do your set at an 8 iron length of 36.5″. To do that means every head now has to be made to weigh around 274g, depending on the weight of the shaft and grip you intend to use. Your 4 iron now probably weighs around 246g, 5 iron is 253, 6 iron is 260 and each head increases by around 7g in a conventional iron set such as you have.

      To get the weight up to 274g would require welding steel to the heads which would make a real mess and possibly the heat from that could warp the faces to not be flat anymore. if you try to put that much weight on using lead tape, a 4″ long strip of half inch wide lead tape weighs 1 gram. That gives you some idea how much lead tape would be gobbed to the back of the heads. And then you have the issue of the #9, PW, GW and SW in your set. Those heads would need to LOSE weight to get down to the 274g spec. Only way to do that is to either drill a bunch of holes in the back of the heads or grind a whole lot off the heads, which would change the size and shape. Then you;d have to bend all the lies to be the same, which for a forging like the MP54 would be the easiest of the tasks you would face.

      In the end you would have a real mess on your hands trying to convert a normal set to a single length set.


    • I actually have a set of 560MC heads that I’m modifying for a single length set. I have been using the 560’s for 8 years, and in that time I never found a set that I liked better despite trying dozens of different sets, so while I was waiting on my Sterlings I started a project of converting a backup set of 560 heads to SL heads – but haven’t finished yet. I’ll let you know how they turn out in case you want to try the same thing with your Mizunos.

      In the meantime though, I sure am loving my Sterlings! I just played my 4th round with them yesterday (only 9 holes) and hit 88.9% GIR! I only missed 1 green, and ironically it was a 185yd par-3 where I used a 5-iron and flew the green by 10 yards because it actually hit that much FURTHER than what I was used to with my previous set! So I’m still getting used to the distances with the Sterlings, but each round is definitely an improvement over the last. My 2 previous rounds were 67% GIR (2nd round) and 72% (3rd round), and now 88.9% (albeit only 9 holes). For comparison, in the past I think my best round ever in my life was maybe 75% GIR with my average being around 50%.

      Iron play has never been a strong area of my game. Driving, chipping, putting – no problem. But everything in between with y irons is what has always gotten me in trouble. It looks like these Sterlings are just what the doctor ordered!

    • JAMES

      Wow, how nice it was for all of us to have the chance to read your comment and note your experience with the new Sterling irons!! we’re been VERY HAPPY to have had the chance to hear a lot of similar reports from Sterling users since we began to release the model in late March. Being able to hear stories like yours is the part of club design that is a whole lot of fun for me !!

      Thanks much and the very best to you in this great game,

  96. Hi Tom, built the Sterling Single Length iron set today and must say I’m impressed with the look, quality build of the heads, went like a dream.

    Using the TT XP95 #7 S300 shafts, tip cut 1/2″ and built to 36.75″ after doing a dry fit of the lightest head for a reference point. Used brass shims and cut off every 2nd finger, this gave a nice and tight fit.

    #5 to #9 at D2, PW and GW at D3 as PW was D2.7 without any hosel weights.

    Only needed 2 gm hosel weights in #6 and #9 clubs, and ground down 4 gm to 3 gm so GW finished at D3. I’m that precise, these are my clubs to use plus demo for friends.

    I wished I could open an account with you, but was advised as another stockist is about 30 Kms away from me, you won’t start the account.

    I’m semi-retired now and have no plans to advertise, just like to continue dealing with my strong group of clients that trust and love my work, quite a few have already mentioned they want to demo my Sterling iron set.

    Kind Regards, Ken ;<)

  97. Hi Tom,

    I’ve always played the ball a little further forward in my stance with a 5i than a wedge. In your hit testing, have you found that still to be valuable? Or is this another variable that the single length irons eliminate from the swing?



    • When the lengths are all the same, the ball position should be the same. There most certainly is a tendency for golfers to WANT to push the ball more forward in the stance with the lower loft Sterling irons. If you hit the ball well doing that, fine. But the original intent was to correspond to the same ball position since length, not loft, is the determinant of ball position for clubs.


    • Brent,

      Having played around with the Sterlings for a few months now, I can tell you that the thing which took the most work was not allowing myself to play the low-lofted irons forward in my stance like I have always done. Whenever I do that with the Sterlings I hit the ball thin because my club is bottoming out behind in the middle of my stance – like it would with a typical 8-iron – and therefore I end up catching it on the upswing and blading it. It has been a struggle getting used to playing all the irons from the exact same spot, but once you can get over that mental block the results are incredible! I had a back injury about 6 months ago so I have only been able to take limited swings at the range and hadn’t been able to actually get out and play a full round with them until just last week, and I shot an 84….with 44 putts!! The course I played at had just aerated the greens so everyone’s putting was atrocious that day, but that just shows you how good my approach game was being able to shoot in the mid 80’s with that many putts! If the greens were in better shape it would have easily been a high or even mid-70’s round (and I’m a 12 HCP!). Not bad for my first full round in 6 months coming off a back injury!

  98. Hi Tom, received my Sterling heads today from GSA.

    I’m using XP95 taper shafts that I’ll tip cut at least 1/2″.

    The XP95 shafts are around 30gms lighter (approx. -3 SW) than Dynamic Gold shafts you refer to when talking about tolerances, to get to D2 SW using #8 iron length of 36.5″ even using your 9gm tungsten hosel port weights, do you foresee any problem with me using shaft tip weights as well. I’m referring to playability.

    P.S. I dislike using weights unless necessary

    • A couple of the Sterling heads are around 271gm so I’ll need 3gm just to get to the 274gm standard, plus need to make up around 30gm because of lighter shaft weight.

    • KenMar
      As with every clubhead that is manufactured with a carbon steel body and chrome plating, the tolerance for weight is +/-3g. Fortunately not many of the production heads come out at -3g from the 274g spec weight, but it will happen. First, every one of our clubhead models has a hosel weight chamber located at the bottom of the shaft installation bore. These are there to enable clubmakers to use one of our weight plugs to add weight during the assembly process to achieve the final swingweight they need. Few other clubhead companies do this to allow clubmakers a chance to achieve the final swingweight they may want by adding weight inside the head. We make the weight plugs in increments of 2g, 4g, 6g and 9g – we sell the weights in packages of 12 per each weight increment or we offer an assorted pack with 3 of each weight plug increment.

      There is NEVER going to be a time when a clubmaker can get clubheads that just perfectly end up being the right weight for each head when combined with all the different shaft weights, lengths, and grip weights to end up with the particular swingweight. There are so many combinations of length + shaft weight + grip weight and swingweight that golfers might need – so a good clubhead product line has to have a way to add weight when needed to achieve that final swingweight for each golfer. That’s why the weight chamber is in every one of our heads and that’s why we sell the weights to epoxy into the weight chamber during the assembly of each club.

      Hope this helps,

    • KenMar
      If you ever do have to use a tip weight in addition to a hosel bore weight, you can do that. For the Sterling irons that is ok because the effect of more weight in the hosel end of the club is less evident on performance when the lofts are higher such as a set of irons. Where you want to be careful not to add too much in the combination of hosel bore weight + shaft tip weight is with the driver and fwy woods. There you would be advised to try to keep the total amount of hosel weight + tip weight to not be more than 12g in total.


  99. Tom I’ve been an avid follower of your writings and work for over twenty years. I really think you’re on to something here, and have done a great job with these. I built my set out last week and have played twice with them. Here’s my review
    36.5 length D1, Project X 95 steel shafts

    As good as any iron on the market, nice setup behind the ball inspires confidence.

    Terrific soft feel of the ball coming off the clubface, sound equally good.

    As good as my current OEM clubs. My distances are nearly identical to my current clubs. No longer and no shorter.

    This is where the product really shines. Distances are amazingly consistent. Likely because I hit the sweet spot every time, which of course is the logic behind this. Ball striking was amazing, I can’t hardly miss an iron and when you hit it sweet each time amazing things happen.

    Accuracy is spot on!

    Overall I’m quite impressed and find myself asking “why wouldn’t I play this? I can’t really thing of any downsides or negatives to switching over.

    If this catches on, and gets refined a bit more it can only get better

    Great job Tom

    • CHRIS

      Thanks so much for sharing your experience with us that you are having with the new Sterling irons !! We really are pleased that you were close enough to Geoff to have the chance to choose to work with him for your fitting needs. I can’t say enough positive things about Geoff and I have been so fortunate to have had the chance to know him over the years in this side of the business. I really think that what we hit upon in doing this more recent single length design is the matter of how to create it at a shorter length than what had been done before, and still get proper distances, while then gaining the benefit of more consistency from the shorter length. it is a fun set to play !

      Thanks again and the very best to you in this great game,

  100. Hi Tom,

    I first stumbled across these clubs (had never heard of you previously) whilst looking into this kind of Iron design; and since seeing Dechambeau come onto the seen I’ve been intrigued by the concept. not thinking I would be able to try these in Australia I was surprised to see you had a fitter in Melbourne and thus made contact with Geoff Waldon, who has been fantastic to deal with. I have to say that when trying a demo set I was blown away by the look, feel and performance of these irons and as others have stated on here I too have found increased yardage on the 5 iron, although I can see that chipping will take a little bit of adjusting to. I must say that I really love the ping those low irons make. I have placed my order and cant wait to receive my new Sterling’s next week! 😀

    Keep up the great work!

    p.s looking forward to trying out some of your other designs.


  101. Thank you tom for the swift reply.
    It is a big shame, really big.
    For too long lefties have been discriminated against up and down golf shops in the UK. No fault of the shops just as you say the sheer number of lefties is alot lower !

    Hopefully in the near future it is possible for you to create the LH version and I will be first on the list

    #justiceforlefties 🙂

    • JIM
      I realize when looking at this from the other side of the ball, it can look like discrimination. But it really isn’t anything more than a supply and demand thing. In the USA, left hand players are 6% of the market. In Canada it is 15% and in Sweden it is 12%, both higher because of the influence of ice hockey when kids who have played a lot of hockey decide to learn to play golf. Added up it becomes that 8% blended percentage vs the right hand clubs. And unfortunately 8% is not a big number. In the end, we needed golf clubs to have evolved like rackets and bats – one model works for both RH and LH !!


    • Well .. it is only a production cost problem. I am sure that you tell Tom that you are ready to pay 200US$ / head, then he may consider having more LH heads.

    • Tom,
      Here’s a wild idea. Have you ever considered something like Kickstarter to fund the development costs for a Left Hand version of the Sterlings?

      Given the buzz it might be worth a look. No one gets charged anything unless the target goal is reached.

    • ED:
      Thanks Ed, but I would not touch that with a ten foot pole to have a hundred or more “bosses” involved in anything I would do with a golf club. I am not a team player in stuff like that. I guess it is why I prefer to toil in relative anonymity in this side of the industry on my own rather than to have ever accepted any offer to work for any big company. But thanks for the suggestion !!

    • All the lefties of the world need to cheer for Bryson to win some tournaments. The more success he has, the more buzz there will be for single length irons and the more sets Tom will be able to sell.

      I’ve already seen some nice buzz and it seems like these things are on permanent back-order.

      I selfishly am hoping for that level of success as well… Dad and Daughter both hit from the wrong side of the ball and I want to build them some Sterlings!

    • BRENT

      thanks very much ! And we are really working on the goal of offering the Sterling irons in Left Hand. we’re very close to making that happen. Actually, while there is no question a win or a few more top 10s from Bryson would continue the education of golfers about single length irons, I happen to think that it will get a big shot in the arm when Cobra introduces their single length model – whenever in the near future they plan to do that. There is little question they will do that – they can;t sign Bryson and not do that. When that happens, there will be reasonable marketing behind the set which in turn will make more golfers aware of it as a viable choice for irons. Since I am pretty sure the Sterling irons will be more expensive than the Cobras (cobra will not be doing these with a high COR face or carbon steel body, I suspect, so that will keep their price down) then we will probably gain some “coattail marketing” from that, and if consumers check it out and see ours is more expensive, there is always that chance for the “Hmmm, if it costs more it must be better.”

      We’ll see, in other words,

  102. Hi Tom.
    Great reading all the comments.
    Are these available in Lefthanded ?
    Looking forward to buying and using if and when they are!

    • JIM:

      We are seriously looking at this for sure. Sadly this has to come down to numbers, which as a club designer, I hate to have to say. Never in my 31 yrs of designing clubhead models has a left hand version sold more than 8% of the units it will in right hand. So the 8% has to be big enough in evaluation to cover all the tooling die costs, production costs, minimum inventory costs and all that hard, distasteful stuff that gets in the way of just plain hitting shots and enjoying the results. Thanks much for your interest and we’ll do our best.


    • Tom
      Again thanks for the reply. I understand, fingers crossed for the future

  103. Purchased a set of Sterlings a week ago. Prior to that I played four rounds with demo set here in British Columbia.
    I play 175 rounds a year and was using Ping G 5 clubs.
    The Sterlings are about one club longer than the Pings.
    – very easy to hit
    – accurate, in fact very accurate
    – be patient with the wedges and shot shots chips. Takes a bit of getting used to.
    The 63 deg lie and the 37 in shaft allow for easy swing plane that results in great shots.
    – yardage gaps 10-12 yards Between clubs.
    I have played for 20 years and these are the easiest clubs I have ever struck. Don’t buy these irons for yardage gains.
    They were made for accuracy and consistently.
    Why the name sterling?? Don’t know.
    The longer you use these the better they feel.
    Thanks Tom

    • Steve:

      Thanks very much for both purchasing a set of the Sterling irons and for taking your time to share your experience with the clubs so far. It’s really a treat for us on this end to have the chance to hear that the model is working well for you and that you like the results so far. The Sterling name came from the golf professional who beat on me hard enough to convince me to design the set – at the time he was living and working in Europe so I think he had the thought to take the name from the UK currency of Pound Sterling to connote the irons have real value and worth !!

      thanks !!

  104. Hi Tom, as I’ve previously stated, my personal shaft preference is the TT XP95 S300 Taper as I know how they perform for me.

    My supplier isn’t purchasing TT or PX shafts anymore as there was a dispute about new pricing structure, increase of about 18%.

    My supplier does have enough TT XP95 S300 #7 shafts for me to build a set of your Sterling iron set.

    Do you personally see a problem with tip cutting the TT XP95 S300 #7 taper shaft by around 1/2″ to give similar performance to uncut tip on the TT XP95 S300 #8?

    I do realise that I will need to use a brass shim or similar when using a taper shaft in your .370″ Sterling irons.

    I would be building the set at standard #8 iron length.

    • It would be ok to tip 1/2″ from all those shafts to duplicate what’s going on with the 8 iron shaft. It would probably make the task of shimming the shafts into the 0.370″ bore of the Sterling irons to be a little bit easier as well.

  105. Tom, we want to thank you for this design. As an innovator you have hit a home run with these. I have been fitting since 1979, building since 1990 and yesterday I had the single best day ever delivering a set of clubs and it was a set of Sterling Irons.

    We had a customer who had come to us in April and had recently purchased every Nike club that the PGA tour superstore could possibly sell him and everything could not have been more wrong in the fitting. He had requested a fitting and wanted a set of these. At first we adjusted the swing weight of all his clubs and helped tune his swing as he was a brand new golfer and was struggling. We didnt want to sell him yet another set of clubs and were trying to help.

    A month later he called again and wanted to try the Sterling Irons as he was suffering miserably with what he had. We met with him again and let him try the 6, 8 and Pitch. He was instantly successful and excited about the prospect of being able to play.So we fit him for a set of Sterling irons.

    We delivered them yesterday and this young man lit up instantly when he was warming up with his new pitching wedge and was instantly successful and hitting straight consistantly. About an hour into the delivery in the rain I might add, I looked at him and as he was smiling and said “you can play golf now cant you, and your confident about your clubs”. He was smiling from ear to ear and said “Yes I can”.

    For a complete “Newby” to golf to be able to strike the ball consistantly with over 85 balls with a brand new set, coming from being completely incapable of striking two balls consecutively straight was amazing for us. I was so happy and felt so good that we were able to help this young man walk into his dream of playing golf was the best feeling I have had in a long time. We always get excited with every club we deliver, but this was special, this man could not hit a ball with the clubs he had AT ALL. There is no other way to describe it, and with your single length design he was instantly succesful and had the confidence to persue his dream and enjoy the feeling instead of loathe the feeling.

    Thank you what a great design, and that mechanical noise, you have in the 771 CSi as well, but thats to be expected. We have sold them to a 2 handicap and they get a kick out of the sound! Keep it up we love everything you can throw at us no complaints at all from any design aspect absolutely a complete home run! Making this fitter of 30 plus years feel like I did was phenominal as a bystander.

    • Thank you Fred !!! But seriously, with your fitting knowledge and experience and even more, your care that you put into every job you do for a golfer, I know that what you report here is definitely “par for the course”. . . no, it’s definitely better than par with you doing the work for the golfers !!


  106. Tom,

    I have built two sets of the Sterling irons now for two customers. One customer (and a few on lookers) is a little put off by the “ping” sound of the high COR 5,6, and 7 irons. Is there anything that can be done to mute this without hurting performance?


    • DENNIS

      Well, I guess there is a first for everything, as this is the first time we have heard of someone being bothered by the change in impact sound due to the high COR face. You might be able to cut this down by putting a piece of duct tape on the back of the face. it won;t add hardly any weight and it won’t cut down the face flexing for the performance. Might look a little odd, but it should help.


    • Thanks Tom. Sorry, I don’t mean to be a problem child:) I was surprised as well.

      I have been very impressed with the Sterling iron design as it gets results. I am waiting on my third set, this one will be for me….

      Thanks again,

    • Dennis

      Please, I am the one to apologize – I didn’t realize the manner of my response conveyed a critical impression. It was just a little strange or rather a little different for me to accept that some golfers just might overlook the whole performance side of this model to spend more time focusing on the impact sound instead – when we have had the same face construction out there in the form of the 771 irons. Anyway, time for me to drop that !! Thanks much Dennis !!!!


    • Tom,
      You are most gracious. I thought I would follow-up with you and just let you know how I made the customer happy.

      I took two 1/2″x1/2″ clear rubber squares (the kind used to keep cabinet doors from slamming) – stacked them on top of one another and wedged that stack in the gap of the cavity pretty much located on the sweet spot of the face. It appears to have no negative impact on performance and the “ping” is gone. I am not sure on how long it will remain in place or if a stronger adhesive will be required.

      I hope this doesn’t offend you in any way as I didn’t see a need to do this but I just wanted to make the customer happy.

      Thanks again,

    • Glad to hear the customer is happy. Without question that is the guiding principle of business !!!

      Thanks Dennis !!

  107. Hi Tom,

    What is the bounce angle on each of the wedges? Are they adjustable?


    • James:

      Sterling PW and GW bounce is 6* for both. The SW is 11*. You cannot change sole angle without changing loft at the same time. The two specs exist in a permanently connected relationship. So for each 1* you bend the loft higher, the bounce increases by 1* and vice versa.


  108. Hi Tom

    Are many people using these to replace the longer irons, whilst keeping the short irons from current set up?

    I am really excited by these. I currently use 560MC’s which are only a couple of years old. I love them, but I love new gear just as much.

    • Jonathan

      No, people are not trying to combine a part of a single length set with a part of their current incremental length set. The reason is because you destroy one of the key potential benefits of the single length design concept if you do that. You identified one potential benefit, that being the possibility of hitting lower loft irons more consistently because their length is now shorter in the single length set than in the conventional set. But the other key benefit, which really is THE first reason single length was conceived in the first place, is the fact that when ALL the irons in a set are the same length, they now all have the same identical swing feel and they are all played from the same ball position, stance, posture, swing plane. When all irons are the same length, every possible element that controls swing feel and swing consistency is identical in each iron. So if you blend a part incremental length set with part single length you lose that potential benefit.

      At the same time, if you want to try your concept, by all means you can do so. Because in doing so, you do still have the potential to achieve the first benefit of being able to hit the lower loft irons more consistently. And since you say you really like the 560s that is a good indication they do fit you pretty well. So I would say since you love new gear, give it a try.


  109. Hi Tom, Is it fair to say that if the Sterling single length iron set are designed around #8 iron length, that you use #8 iron shafts for the whole set. I prefer to use taper tip shafts as I find them more consistent.

    • Yes if you planned to use taper tip shafts in the set, you would need to get all 8-iron raw length taper tip shafts for all the heads in the set. And be sure the shimming of the shafts in the 0.370 bores is done right.


  110. Tom, I was a 2 hcp player 2 years ago, a couple injuries have set me back a little.

    Anyway, are the Sterling irons a set that can be used by very low single handicappers, or do you see them more as a Game Improvement iron set.

    I’ve always hit my #7 to SW more consistently to #4 to 6 irons, do you believe it would be feasible to add Sterling #5 to #7 irons to say my Callaway Apex Forged 2014 irons, or would distances between clubs be off.

    • There are low single digits and club pros playing with the Sterling irons now. The head pro at Erin Hills where next year’s US Open is to be played just ordered a set last week in fact. Sure, it is not the classic all forged carbon steel set, but it’s definitely fine for good players. The guy who “inspired” me to design the set is a pro who has played occasionally in European Tour events and is a top competitor in speed golf tournaments (shot 71 from the tips at Bandon in 56 mins) and he plays the Sterling irons.

      Sure, it is possible to hit lots of shots, look at distances in comparison to other clubs, and tweak lofts to match Sterling heads to the rest of another set. the 5, 6, 7 are not the easiest to bend because of the way the heat treatment for the face strength causes the hosel to be a little stiffer, but it’s possible to tweak those heads +/-2*. Thing is though, the biggest reason for single length to even exist is to offer the golfer the identical swing feel and posture/plane for every iron. Not just a couple of them. but with time in hitting shots and working on it, it could be possible to blend some Sterling irons in with other irons.


    • Tom
      I played the 1iron since august, and i love the feel in the LW in that set. Now looking into the specs of the Sterling its exactly how i would like it. But i would need a LW in the same length. Its really easy to hit, and when all the other clubs have the same length it feels really strange with a short LW. I tested today… No chance you could rethink…? 🙂

    • You can always play the LW from the 1 Iron set and have it cut down to 36.5″ and re swingweighted. That would work fine I am sure.


  111. One idea i had was to use one of your other hybrid designs and then use hosel weight to get to 274grams. Is something like that possible?

    • HARRY

      The hosel weight bore allows +9g and the sole weight bore allows +9g, so 18g is the max you can add to one of those heads. it is possible to also use a shaft tip weight for maybe 5, 6, 7g on top of those two weight bores to maybe get to a total of 23-25g added at max. But even with that, you could only get the #5 and 6 hybrids up to 274g. No way with the 2, 3 and 4 hybrids. But the real problem is that if you were to somehow be able to make a 2 or 3 hybrid to be a normal swingweight at 36.5″, that length is so short when coupled with the lofts of 18, 21 that unless you had a very high swing speed, you would not hit those clubs far enough.

      No, if the rest of the set is ever to be brought into the single length concept, it would have to be a combination of the woods and hybrids above the irons that would have to be made to a single length that is longer than the single length of the irons. But even then, that would be tough to do so the 3 and 4 woods could be long enough to get enough distance while not making the 3, 4 hybrids to be too long.


  112. I am loving my Sterling Irons with Recoil shafts. Spectacular. But I really want a 6 hybrid to match at 19 or 20 degrees. Since there is no Sterling 6 hybrid, can you recommend a hybrid with a similar weight head so I can get one built? Also, is it reasonable to bend the 5 hybrid by 3 or 4 degrees or isn’t that going to mess up the face angle and bounce? Thanks in advance for your answers Tom.

    • Harry
      I got the add on message about the loft you need being 27-28*. It is possible with our 775-5 head to get pretty close to a 274g headweight and bend the hosel up to 63* so it could go with the rest of the Sterling set. Spec loft on the 775-5 is 27* but we could hand select for 28* or 26* if required. As I mentioned in the other response about hybrid head weight and our twin weight bores, you could ask us to hand pick a 775-5 at a heavier weight of maybe 255g. Then you can add 18g to the two weight bores on the head to get to 273. And if you needed more than that a tip weight in the end of the shaft could do that. The hosel would need to be reamed to 0.370 to match the rest of the Sterling set to use the same iron shaft you use in the other irons. But it is possible

  113. Tom, any thoughts on a set of shafts that is specifically tailored to a single length set or is that completely unnecessary? I was thinking about something similar to the old Royal Precision Flighted Rifle shafts that optimized trajectory throughout the set. Now, those shafts were made for a incremental shaft length set but what if we had the same characteristics in a same length set of iron shafts? The one I envision would be tip stiff in the higher lofted iron and progressively shift to be tip soft in the lower lofted irons. Any merit to this line of thought? I was thinking that such a set of iron shafts would make a already great set of irons even better. I was pondering if bend profile in the shaft of my same length 7I is the optimum choice for my SW or my 5I?

    • Matt:

      No, never. A shaft design has nothing to do with the head into which it is installed. Shafts are all about the golfer, specifically his clubhead speed, downswing transition force, downswing tempo, point of release and if the golfer has over time developed any preferences for the bending feel of the shafts in his clubs. There is no such thing as a shaft that matches to a head design. if the player himself decides that he wants a change in the bend profile of his shafts within ANY set, single length or not, then you can do what you are talking about. But something like that would be a personal preference of the individual golfer and have nothing inherent to do with the head design to be done for all golfers.


  114. Another vote for these in left-handed, please! Golf is hard enough. These would help make it easier.

    • Oh yes please! I am absolutely buying in to this idea fully. Let’s make them make leftys!

    • Please LEFT HAND

  115. Tom,
    I met up with Craig Weakley aka “the golf club guy” in my own local of Anacortes, WA.. and ..he built me a Sterling 6 iron demo club,that, he hadnt even hit himself!
    Well, what is there to say but “wow”.. This thing is so fun to hit. Its nice to see what a 6 iron shot is supposed to look did take a little adjustment but im going to be hitting balls with it over the weekend and put it in for a round on friday so im excited for the next few days of practice..
    Great feel and so much more consistency.. Its kinda refreshing and alot more reassuring grabbing that club, taking a 8 iron swing and seeing the 6 iron distance, i just feel way more relaxed and at ease..thats not to say i didnt hit some poor shots, i did. As i said, learning curve for sure…The club has great feedback and well struck shots are definitely rewarded while miss hits are noticable but there is a great deal of forgivness as feels to me like its just borders a game improvement iron with a flare of a betters iron built in..
    I am going to get fit on monday, again with Craig and am excited to see the nunbers..cant wait! OTR days are…great job with these Tom..

    • Shelby

      You use a very appropriate term – fun. That was a term that came out a lot in hit testing for the set and especially for the low loft clubs in the set when we were doing hit testing last year. it’s a very good way to describe the difference between a single length and incremental length set !

      Thanks !

  116. Dear Tom,

    I’m a club maker in Adelaide, Australia and very interested in the concept of Single iron length set especially for people new to golf.

    Am I able to purchase a set, even heads 4-PW + AW and makeup to initially test myself, with the thought of importing to Adelaide, Australia for resale.

    I usually use myself a low offset forged iron set. Have you considered a reduced offset Sterling iron set for the BETTER PLAYER?

    • KEN

      You are able to purchase any of our designs if you just take the time to set up an account with our company. To do that, go to and look for the link at the very top of the home page for ACCOUNT APPLICATION. click on it, fill out all the information and very shortly after you click to send it to us, we will be in contact with you to get you all set up with everything you need to know to do business with us. Thanks very much for your interest !!

      If single length were to really take off to gain a lot of interest and awareness, then it would be possible to develop other versions/model types the same way that multiple model types are created for conventional incremental length irons. You have to realize that incremental length irons have been around and accepted by golfers for centuries. As such it is very easy for a company to develop many different specific model types for traditional, somewhat game improvement, super game improvement, etc.

      In such early days of the beginning of golfer awareness about single length irons, we and anyone else in this industry have to walk before we run. WE have to see that the demand is there and that the demand will remain strong and growing before it could be possible to create other versions of a single length concept. You cannot possibly start a single length model with a small, forged, traditional type of head model because that market is way too small to support such a start into single length fitting. You have to begin with a model type that can appeal to a much larger segment of players. Then take it from there depending on reaction and support.

      Thanks again,

    • Do you have any 60 degree LW to this set?

    • Mattias

      No we don’t and I doubt seriously I will agree to design a LW for the single length set. Not enough demand for one, but such a club at single length of 8 or 7 iron length would be seriously hard to control and get used to hitting solid and on center. if the golfer is used to a LW or needs one because of the green design of the course(s) he plays, it would be better to play the LW the golfer is used to at the shorter length it undoubtedly is.


  117. This is such a brilliant idea, wow!
    I have two questions, are they suitable for Senior golfers who use lightweight Graphite shafts and are they available in the UK?

    • PAUL

      Most certainly ANY iron model that has the proper game improvement features for your manner of play and ability can be fit to perform well for you. Fitting is a matter of analyzing the golfer’s swing characteristics to know what the best combination of fitting specs should be to enable you to play to the best of your given ability. So the Sterling irons like any of our irons, could be fit with heavier stiffer shafts for players who are stronger, more aggressive and with higher swing speeds – they can also be fit with very light, flexible shafts for players who are much less strong, very smooth and passive in their swing and with slower swing speeds – and they can be fit for any golfer in between these extremes.

      What has to happen is that you need to find a competent clubmaker in your area or in reasonable proximity to where you live. To do that, please take the time to call or email Diamond Golf International in West Sussex. Call them on 01903 726 999 or email them at and tell them where you live, ask them to provide you with the contact information for the best clubfitter in your area.

      Our supply of the Sterling irons is finally at a point that we will be able to open up distribution in the UK very, very soon, like within the next week or so. All of the custom clubmakers are independent business people, not tied to us or to Diamond Golf in any formal or contractual manner. Therefore when you have identified a clubmaker in your area, you’ll need to call him or her to inquire about services and pricing.

      Thanks for your interest,

  118. For anyone who wants to watch a nice in-depth video review of the Sterling irons done by golf gear reviewer Mark Crossfield, you can check it out here:

  119. Thank you so much for the well detailed response.
    My 7 iron has been shortened to 36.5 inches and 2 degrees strong (32*)so I am sure the fitter can get it so the 6 iron will blend right in.I will definitely be ordering at minimum a 5 and 6 iron.
    I currently carry a 8 handicap and the only clubs I seem to have trouble with are those darn long irons.
    I hit my 43″ Driver great usually around 250-270 yards and I also hit my 42″ 3 wood great around 225 yards but when I get the 3,4 and 5 irons in my hands they are the most inconsistent clubs I have.
    I myself don’t personally need to have all my irons the same length as I actually like my wedges,9 and 8 irons slightly shorter but I do just love the idea of having no irons longer than 36.5 (MY 7 IRON) and still get the distances I need.
    Thank you so much for your expertise,I am looking forward to getting fitted for those “long” irons

    • joejoe

      Let us know how this works out if you would please. This is a pretty interesting concept for paring off a part of the single length set for a specific reason – which makes sense. Of course you can’t achieve the same swing feel with all irons when you do what you want to do. but on the other hand, since you have struggled with the low loft irons, there is no question the longer length is a part of the reason. So we’ll be curious to hear how your distances are compared to your old 3, 4, 5 irons.

      Thanks, good luck with it !

  120. Tom
    I have made Sterling sets for two customers and they love them. One customer is a high swing speed player. IF we wanted to approximate a “Sterling 4 iron” could we take the 771CSI 4 iron and bend the loft and lie to fit below the Sterling 5 iron (as well as adding a lot of weight to it to match the Sterling weight)?? What do you think of that idea?

    Dennis Corley

    • Dennis

      That’s a better idea to do it that way with a 771-4 than to try to bend loft down on a Sterling 5 iron but that is a ton of weight to have to add. I do have some sterling 5 hybrid heads that I caught with 21* loft on inspections of the shipments. We can offer you one of those if 21* is good enough . or the other solution with that is to take the 21* hybrid, bend it to an open face angle, then if the golfer is always told to turn the club so the face is held square behind the ball at address, rotating the open face back to square lowers the loft to get it down to be 19* if you want that. I just did that on a strong hybrid for a clubmaker this week. And when building the club if you install the grip so the grip is square when the face is rotated square, then it is easier for the golfer to remember what he has to do with the 5 hybrid to get it to be 19*.

      Your choice, we can help,

  121. Can I purchase only the 5 iron and 6 iron since I don’t want to change my 7-pw?

    • JoeJoe

      Since all of our designs are available through independent custom clubmakers all over, you could have the clubmaker make any number of any of our models that you would want. Working with a clubmaker is not like buying from some big golf store where they may not want to sell you single clubs. The clubmakers will make anything you want.

      That being said, I would guess the reason you are thinking of doing this is so you could possibly get a 5 and 6 iron which would be easier to hit than your current 5 and 6 iron – because the Sterling 5, 6 irons would be a good bit shorter than your 5, 6 irons are now. That is a possible for sure. But the big thing you would need to know before you do this is what will the distances be that you hit the sterling 5, 6 irons and what will be the distance gap between your 7 iron and the Sterling 6 iron. It could be with the lofts and high COR face of the Sterling 5, 6 irons that there could be a longer gap between your 7 and the Sterling 6 than you would like to have.

      How do you figure this out? Well of course the best way would be to test hit/demo a Sterling 6 iron while you also have your current 7 iron with you so you can hit both and very carefully note how far you hit each one to see what the gap will be. That you can only do if you work with a custom clubmaker who handles his business with test clubs and demos. To find a clubfitter in your area, you can head to, go to the middle of the home page to see the FIND A CLUBFITTER search tool. click on it, input your location, contact the clubmakers closest to you, explain what you have in mind, and ask if they can accommodate you.

      Only other way to figure this out would be to compare the loft and length of your current 7 iron to the loft and length of the Sterling #6. Sterling #6 is 36.5″ and 27*. Your 7 iron is probably 37″ but you’d have to check the company’s website to try to look up what the loft is – or call them to ask. Your 7 iron could be anywhere from 35* down to 32* in loft based on avg lofts over the past 10 yrs or so. If it is 34-35* you probably will have a larger distance gap from it to the Sterling 6 iron. If it were more like 32*, then you’d probably have a manageable gap to the Sterling 6.

      Hope this helps, thanks for your interest,

  122. Hi Tom,

    Huge response to these irons. Replying to all these comments must be 70% of your day!

    I love the concept, but now that I’m thinking about pulling the trigger, I’m worried about distance gaps in the short irons (although I guess we can’t call them “short irons” anymore, haha).

    I play all Wishon clubs now with perfect 4 degree increments all the way from 60* to 16*. So my new 9i would be 4 deg stronger than my old one AND it’ll be a little bit longer. I hit my current 9i about 145, so the new one would be… 160ish? I’d have a situation on my hands where I’d need 2 gap wedges or I’d have 20 yard increments between clubs (which is too much on the short end of the spectrum).

    Have you come across this problem in your testing?

    thanks for your response!

    • Brent
      No, about 25% !! It has increased though ! Which is a good “problem” to have !

      Please do not take this the wrong way, but you’re making a bigger issue out of this than it will be in the end – and two, it is no different than what any competent golfer has faced whenever they bought a new set of irons over the past 20-30 yrs. bear with me here, because this is important.

      Back 30 yrs ago, the average 5 iron was 32* loft and the avg PW had a loft of 52*. Over the years, lofts have gradually but steadily decreased on irons to the point that today, the avg 5 iron is around 25* and PW around 45*. Anytime a golfer went 5-6 yrs in between purchasing new irons over the past 30 yrs, more than likely when he bought the new set, he “had to get used to” new distances with each iron compared to his old set. But no one made a big deal about that as some are doing when viewing the prospects of going into a single length set. Now it’s a big deal to the point some won’t try a single length set to even see what the benefits could be.

      Yes, if the lofts of the Sterling irons are lower than your irons, you will hit them longer. No different than if your last set of irons were 10 yrs old and you were shopping for a conventional incremental set of new irons today. But in 2, 3, 4 rounds you will be used to it. And the distance gaps will be just fine.

      If you want to say that’s a downside, then I can word it this way – the only “downside” to playing a single length set is that you will need a short time to readjust to the distances of each iron number compared to what you were used to before, but once you do that, then you can have the chance to see if the benefits of same identical swing feel and same identical stance/posture/plane will kick in to make you a little more consistent.

      All I can tell you is that thousands of people have bought these irons and we’ve not had one complaint, nor one person ask for their money back.

      thanks for listening,

    • Thanks for the response, Tom.

      I know you already know this, but when the PW dropped “all the way” to 48*, golfers realized they needed a Gap wedge to fill the hole. But now that PW has dropped all the way to 44/45, I feel like I need a second gap wedge.

      I only hit my LW 80 yards or so… so if my 9i goes 160, then I only have SW, GW, PW to cover 80 yards (20 yard gaps). Thus the concern with not having enough clubs to adequately cover that heavily-used real estate. Pinpoint distance control is much more important with the short irons.

      I think my fix would be to keep my current 60, 56, 52, and 48* wedges (all same length) in the bag and start the single length set at PW. I’d have 2 clubs labeled as a PW, but they’d go very different distances due to loft and length. I guess I’ll never know which way is best unless I build the whole single length set and go out and test test test!

    • BRENT

      Of course with the wedges it most certainly is a very individual preference. I can tell you that after all of our testing was done and all final decisions for the Sterling iron were complete, I had one of the test sets in my bag that fit me and I just kept playing them. I could not get myself to go back to my 560MC forged irons I had played for the previous 7 yrs straight – mainly because the Sterlings were just fun to play with. So I went from a set in which the 8, 9, P, gap, sand were 38*, 42*, 46* and 50* to the Sterlings where the 8, 9, P, G are 35, 40, 45, 50. I have kept my old SW because I am so used to it and I use it for many different short chips and pitches.

      With my old irons I hit the 8 – 155, 9 – 142, PW – 130, gap – 115, full swing with the SW is 105. With the Sterlings at 36.75″ I hit the 8 – 165, 9 – 152, PW – 140, GW – 125. For those full swing irons, I have had zero problems getting used to the longer distances. I just know to take about a club less than before on average when I play my regular course.

      While I know this leaves me a 20 yd gap to the SW where it was 10 before, I have yet to find that a problem. For one, I havn’t seen many shots at 110, 115 – but when I have seen distances in between the gap and SW, I grip down on the gap or use a 3/4 to 7/8 swing with it just the say way I have learned over the years to use a half, 3/4, etc swing with the SW. I know I could reduce that if I were to go with the Sterling SW but I just prefer using my old SW at its shorter length just because I am so used to knowing what it does for different shots.

      But for me, after having played a conventional incremental length iron set for 50 yrs, there is something very interesting about hitting a 5, 6 iron which are noticeably shorter than I was used to with these clubs – it’s fun because with that shorter length, I know I can hit the ball more on center than before. it’s not huge but it is there and it’s one of the things that makes the single length set fun to play. It’s not going to put me on the first tee of the US Sr Open this summer – but it’s just a fun set to play with.

      Hope this helps,

    • Ever indebted to you for being such a willing teacher.

      Thanks Tom!

  123. What would the price be in purchasing a set of these single length irons?

    • Kainen
      Thanks very much for your interest. Sterling single length irons are available through two different options.

      1. Custom fit and custom built for golfers by independent custom clubmakers located all around the US and internationally. But the clubmakers are not everywhere. To see if there is a good clubmaker in reasonable proximity to your location, we welcome you to head to the FIND A CLUBFITTER locator search tool on our website that is here – The clubfitters are ALL independent business people so they set their own pricing for their services and for the custom fit clubs they build for golfers. you’ll need to call and inquire of pricing from the clubmaker(s) in your area.

      2. If you wish to purchase directly or if there is not a clubmaker convenient to your location, you can head to . Scroll down the page to see the set makeup options. You can click to see pricing and to see the options for ordering either by you inputting your specs if you know them, or by answering a series of questions from which we can determine your fitting specs for the irons.

      Thanks very much !

  124. Can these irons be purchased directly from Wishon Golf or do they have to be purchased from a clubfitter on your list? The nearest to me is over a hundred miles and I don’t feel I need to drive that far to be measured for a couple specs. I play with a Moe Norman type swing, Golfpride Jumbo Tour Wrap grips so would need the extra half inch length. Please let me know if these can be ordered directly from you. Thanks.

    • JERRY

      Yes, in the case that you are not near to a clubfitter, we can step in to help. We would have to special order the GolfPride grips you wish to have but that wouldn’t take too long. let’s do this – send us an email at and if you know your specs for the length, lie, shaft model and flex, swingweight, grip model and size, include that and we can take it from there. Since you are using a Moe Normal single plane motion, you would need to input all your specs to us so we could be sure to custom build the irons properly for your needs.


  125. Hi Tom, I was watching Mark Crossfield’s review on these and I’m extremely interested. I live in Canada and am a 5 handicap and I consistently have a hard time striking my 4 and 5 irons and since seeing Bryson on tv I thought that single length irons could help. I’m wondering how much this iron set is and where/how I can order them and also wondering if I was to buy these irons what you think I should do for a 4iron since this set doesn’t come with one?

    • Matthew

      Thanks very much for your interest. First off, I’ll bet the reason you have struggled with the 4 and 5 irons is mainly because their lofts are lower than your current ability to hit those lofts high to fly, and it could be combined with the fact those irons are probably 38.5 and 38 inches in length which can affect how often you can hit the ball on center. A HUGE part of proper fitting is to be fit for YOUR best set makeup. Which just means you honestly find the lowest loft iron you can hit with reasonable consistency to get up and fly, and then above that you go with hybrids or high loft woods that are longer than the irons, but yet still kept short enough that you don’t lose that much control. If you would like our help, please email us at, tell us where in CA you live and we would be happy to check our listings of competent clubfitters to respond with the name and contact information for the clubfitter closest to you.

      Thanks much,

  126. Please make these left handed and through three iron. Please I would pay anything!

    • RALPH

      We’re considering it for sure. We just need to see that these have enough “staying power” from demand before we invest in the tooling dies and inventory for left hand.

      Thanks much,

  127. Dear Mr. Wishon,
    There’s a very nice review on Mr. Mark Crossfield’s YouTube channel.
    It’s never too late…
    Go ahead, never look back.
    Good luck from Italy.

    • IVANO

      Thank you – I knew he was doing a review of the model but had not heard when it was going to be up to be seen.


    • Yes just saw it. They look awesome.

  128. Hi Tom,

    What’s the thoughts behind only going up to a 5 iron?

    Do the lofts become too low?

    In which case could you reduce the loft gap to give greater distance control?

    Would love to hear your thoughts.



    • Stephen

      Yes, for the 36.5″ length we chose to do this with, any loft under what we called the 5 iron loft was too low for most players. keep in mind that all the other single length sets are pretty much based on a 37.5″ length, a 6 iron length. We chose 36.5″ for two main reasons – one, it made all the irons especially the lower loft irons, easier to hit more often on center. Interesting how just one inch made that much difference but it does. Two, it prevented the 8, 9, PW, GW and SW from being enough longer than normal so we do not have to worry about people hitting the wedges too far with problems with accuracy, which can happen with a 37.5″ single length.

      so the challenge with a 36.5″ length was to figure out how to get the right distances for the low loft irons. Part of that was our high COR face design technology. We did the first high COR face iron in 2000, then successive high COR irons in 2004, 2007 and 2012. That high COR face on the 5, 6, 7 also had to be combined with a lower loft so that at 36.5″ length, one could get the proper distance and a little more with these low loft irons. Since the #5 iron is 23* loft with a high COR face to do that, our testing with a 19* head even in a hybrid design showed that pretty much only those with higher clubhead speeds could generate the height at 36.5″ to get that head to fly high enough to carry far enough.

      What we find so far with a lot of heads out in the field now and reports coming back is that most people do hit this #5 iron a little longer than their current 38″ long, 26* 5 iron even at the 36.5″ length. And likewise down through the set gradually until getting to the GW which most say they hit only a smidge longer than their present gap wedge. So the set works very well because most are very happy to hit the same number iron a little longer than before and with more on center hit performance from the shorter 36.5″ length.

      Thus above the #5, one has to look at how far they hit the 5 iron/hybrid in the Sterling set, add 10-15 yds to that yardage, then look for a hybrid or high loft wood to achieve that distance. What many are doing is using a 20* #3 hybrid at around 38-39″ length. Then after that a 5 wood or stronger 2 hybrid.

      Thanks, hope this helps, thanks for your interest,

  129. what are the price of these? im very interested in picking up these irons. been looking at these options for awhile. i am strongly considering picking up these clubs. im assuming you HAVE to go thru a fitting for these.

    • Jason

      Two ways to go about getting a set. One, from independent custom clubmakers all around the country and individually who have an account with us. Right in the center of our home page at you’ll find a search tool for that – Find a Clubfitter locator. All the clubmakers are INDEPENDENT business people so we may offer the suggestion of a suggested retail price but by law we cannot compel them to follow that. so if you work with a custom clubmaker to be fit for a set or your interested, you have to call the clubmaker(s) in your area to ask them for pricing.

      Two is a direct sales channel for the Sterling irons at . You can scroll down the page to click on the set options and from that be able to see pricing. For orders through, the player has two options. You can input all your desired specs if you are confident you know what you want. Or you can answer the fitting questions and we here will analyze the answers to make a recommendation for the specs.

      Thanks very much for your interest, hope this helps,

  130. hi. im jin. im living in korea. i want to test stering iron.

    but if i buy total set together.. tax is to high..

    so can i buy just iron head saperately? if i can.. i can reduce tax.

    • JIN:

      Are you a clubmaker and can you tell us about your training and experience in clubmaking? We cannot offer our designs as components to non clubmakers who would then take the clubheads to an experienced clubmaker to ask him to do the assembly of the clubs. This would be somewhat like buying your own food from the market to take to a restaurant to give to the cook to ask him to make the dinner for you from the food items you bought. The clubmakers tend to be offended when non clubmakers are able to buy the components on their own to then just take to a clubmaker to be assembled. If you are a clubmaker with decent experience, we are very happy to work with you. If you are not a clubmaker, then we ask you to go to a clubmaker to be custom fit and to buy the clubs from the clubmaker. That is how our business works so that we can try to be sure that golfers can all end up with the best fit, and best performing clubs made from our designs. I hope that you can understand.


    • I also would rather just the club heads to get fitted locally. My local clubmaker (drummond golf) is more than happy to fit me and finish assembling them. He is happy because I am spending money on the fitting and shafts with him. I don’t understand why the heads are not available if the customer is able to get them happily fitted elsewhere.

    • GREG:

      In our industry of custom clubmaking there are quite a number of clubmakers who really get angry at companies that sell components to non clubmakers. They see it as akin to a person walking into a restaurant with a bag of groceries and handing the bag to the chef to tell him to make them into a meal but only charge the person for the labor of cooking. These clubmakers spent a lot of time both perfecting their clubmaking skills and studying the technical knowledge of clubfitting. I certainly can testify to how long it takes to become a really good clubmaker/clubfitter. These guys feel that if a person buys components then walks into the clubmaker’s shop to just have him assemble the components into clubs, it is an insult to their level of work and knowledge they have acquired to do what they do.

      At the same time, I understand that there are some clubmakers who just don’t think this way – as it sounds like the clubmaker in your area feels. Our problem is we have no way of knowing what clubmakers feel like Drummond Golf vs the many others who have quit doing business with a supplier who does sell to anyone. We can’t exactly send out a form asking “would you be pissed if we sold our components to anyone”.

      There’s also the fact that I personally would like some assurance that the designs that carry my name are going to be built correctly so not only do they have the best chance of performing as I intended them when I created them, but also so they can look good so other golfers who might see the clubs with my name on them can have a chance of possibly impressing the golfer to result in a new fitting for a clubmaker. If we sell to anyone, I have no way of knowing if those components are going to be built properly. That’s why we screen clubmakers who come to us wanting to buy our designs to use in their fitting business.

      I understand completely that golfers with no experience in the clubmaking side of the golf business can’t understand this. There are component companies that will sell to anyone. In the end, all I want to do is to respect the profession of custom clubmaking because it does take a big commitment to get good in this field. And I want to have the best chance of knowing my designs are going to be put together right. That’s all.

      Since you do say that Drummond Golf does not care if you buy the components and ask them to build the clubs, then fine. If you still wish to purchase the components, let me know personally what you want through an email to . Were you to just call to order, our staff is trained to not sell to people who do not have an account set up with the company.

      thanks for letting me know you did not understand our policy so that I could have the chance to explain,

      We as a company designing and offering our designs as components for custom clubmaking do not have any possible way to find out what clubmakers

  131. Hi Mr. Wishon,
    I have been looking for a good set of irons with the all one length/weight/etc set. I’ve heard great stuff about your clubs.

    Three questions.

    #1 Are these sets available?
    #2 I can get fit near here, or can I get another pro at my club or the one I work with for my swing.
    #3 What is the timeframe for deliver from date of order.
    #4 Can I buy direct or do I buy through a dealer.
    #5 How much is a set 5-PW


    • TOM
      Many thanks for your interest, for sure. Always happy to help with the information you ask for.

      1. First let us explain the options for buying a set of the Sterling single length irons. You can either work with an independent custom clubmaker or you can purchase direct from Through a clubmaker, you would be custom fit, one on one, with the clubs custom built by the clubmaker and bought from the clubmaker. Through, if you know the specs you want, you can list them and they will be matched in the assembly of the set. Or you can answer a series of questions about you and your swing and the fitting specs will be determined, then built into the set for you. If you go through a clubmaker, availability could be anywhere from right away to 6 weeks – it depends on whether the clubmaker has anticipated demand and ordered sets to have in his inventory to use for the customers he may have, or whether he has to order the heads for your set. Right now the demand is still ahead of the supply for us but we are gaining on it. Orders for the heads placed by clubmakers this week (June 1) would be shipped to the clubmaker around June 20 or so. For sets bought through, they have an allocation commitment for the heads with our company set up with us long ago, so any orders placed currently with this site would ship within 4-5 days of when they are ordered by the golfer through this site.

      2. To see if there is an independent custom clubfitter near to you, please head to our website at – right in the middle of the home page you will see the FIND A CLUBFITTER search tool. Input your town/city and the closest clubfitters to you will be displayed. If there is a clubfitter in reasonable proximity to where you live, you would contact them to ask about their fitting services, pricing, etc and to book a fitting appointment.

      3 & 4. I think I mentioned these in #1.

      5. Pricing for Sterling irons fit and bought through a clubmaker is determined by each clubmaker. All the clubmakers who use our designs in their work are independent business people, not tied to us or to any other company from whom they may obtain supplies for their work. As such they set all of their own pricing for everything they offer to the golfers. Thus to find out pricing through a clubmaker, you need to contact the clubmaker you anticipate working with to be custom fit. Pricing for sets bought through is displayed on the website.

      Thanks much again for your interest,

  132. Dear Tom

    I’m 52, 6’3″, new to golf but really committed. 2000+ hits per month/6 months. Practice makes permanent 😉
    I took only one club to practice for my first 3 months (i4,38.5″)
    Q/Will you make a longer set of SL irons? 38″ for 5 to 9? and 37 for the wedges?

    • Eduardo

      No we won’t make a longer set of SL irons. The reason is because IT WON’T PERFORM AS WELL AS THE SINGLE LENGTH SET BASED ON EITHER AN 8 IRON or A 7-IRON LENGTH. And we will never make a set in which some of the irons are one length and other iron are a different length. If you do that, you destroy the main scientific reason that single length irons have the potential to improve shot consistency. Making all irons the same length means that EVERY SINGLE ELEMENT THAT CONTROLS SWING FEEL IS PRECISELY THE SAME IN EACH IRON. Making all the irons the same length means that the shaft flex, shaft bend profile, shaft weight, total weight, swingweight, head weight, MOI, balance point are all exactly the same in each iron.

      Once you start to change lengths, you then change all of these things except you could still have the same swingweight and same MOI if you knew how to do that in a set. But the shaft flex, shaft bend profile, shaft weight, total weight and balance point would be different between the clubs of the two length. Which means you change swing feel in the two different lengths.

      Now by all means, if you want to experiment to see what happens to have two lengths in a set, do it. That’s what is fun about experimenting with clubmaking. BUt single length exists because it perfectly duplicates every element of swing feel. And anytime you change lengths, you change swing feel.


  133. I had a closer look at the lofts, yes the 5 iron(23`) loft is a conventional 4 iron loft. I guess I have been spoilt with the Taylormade Burners low lofts I have been using. With the 3 iron 19` and 4 iron 21`. I think your set would have been perfect with an additional/optional 20 or 21 degree club.
    Do you have one laying around that perhaps you trialled but didn’t go with? Thanks

  134. I am very interested in buying a set of SL irons.
    Really wanted to buy the Stirlings for several benefits over the other brands. Only problem is there is no 4 iron. A club that is needed for long par 3s and second shots to par 5s, of the tee sometimes etc. If the clubhead speed is not generated enough for a 4 iron on an 8 iron shaft, then have it available on a seven iron shaft. Or have it available as an extra outside the 5-PW set, with a disclaimer stating that only suitable for higher swing speeds.

    • I think you will find that the 5 iron in the Sterling set would hit the ball as far as you hit your conventional length, conventional loft #4 iron. The combination of the loft + the high COR face can do that.

  135. Tom I play the single length set. I have a fairly high swing speed. I carry the 5 iron about 220 yards on average. Id love to add a single length hybrid to my set. I was wondering what’s the lowest loft 5 hybrid you’ve found for this set. Id be interested in getting a 20-21 degree #5 hybrid if you happen to have one in inventory thats that low.

    • KOURT
      As a matter of fact, we do have a few of the 5 hybrids that are below the loft tolerance that we rejected and should still just be sitting in a box in our warehouse. I’m the only one who has these heads since I do all the inspections. I am out of town this week, but if you send an email to next week to ask me about this, I can find one to get for you.

  136. Tom, Love the concept of the single length iron set. One of the challenges I have faced in the past, as a moderate swing speed golfer, is that my mid to long irons tend to bunch up distance wise. I see you address that concern in the Sterling set by having 5 degree gaps. No concern there. The only thing that would concern me is my going too far. What is keeping my SW from travelling 2 clubs longer on full shots. Apologies if you have fielded that one already. If you can explain how SW isn’t going to become a PW with the added shaft length…then I’m all in! Thanks.

  137. Tom,
    In an earlier post you shared your carry distances for your Sterling 5 iron, as well as your 3H and 5W. Would you mind sharing your carry distance for the rest of your Sterling irons, as well as sand wedge, driver and driver carry, specs, and swing speed? I think I have a similar swing speed and am curious how your set ended up in distance gaps.

    • I live in Durango, CO which is at 6500 feet elevation. Unless you live at the same altitude, my distances would be of no value to you in making any decisions about this set or about any set. My driver swing speed these days is 93-95, my 36.5″ iron swing speed is 78mph.

  138. Dear Tom,
    Thank you so much for the very useful pieces of advice you gave me regarding the usability of I6, I5 and H5 in the Sterling series for low speed swings. I am sure it is going to interest a lot of seniors and women which represent a high share of golfers.
    Having read a very interesting blog on which you performed in 2015 regarding swingweight, it seems that a proper fitting of the swingweight would be the best way to help maximizing club head speed potential.
    This might enable low speed golfers to use I6, I5 and H5 in the Sterling series which they might be inclined to abandon otherwise (e.g. swingweight too heavy).
    This is an even more important fitting feature due to the fact that a complete Sterling series is composed of 8 clubs having all the same swingweight, and if the one swingweight chosen is not optimum, it is going to be not optimum for the whole set of 8 clubs.
    The problem here is that it is not easy for a basic golfer who makes this sort of ‘’best own swingweight appraisal’’ only once or twice in his life, to determine, within a range of 3 or 4 swt points for which he feels good, which one will be the most efficient for increased swing speed.
    Therefore, within the range of swingweights in which the golfer feels having the best swing tempo and shot consistency, don’t you think that it is the one that will provide the highest ball speed on the radar instrument that should be the one chosen for the 8 clubs?
    The club fitter could modify the swingweight by using lead tape on the club until the maximum distance is attained within that range of “acceptable” swingweights.
    This would have the advantage to give a final ideal swingweight based on concrete radar figures, rather than based on user’s feelings.
    When this is done, the best swingweight for the 8 Sterling clubs is then known for this category of people and may enable them to play low loft clubs like I6, I5 or H5 by using their maximized club head speed potential.
    Or is there another way to optimize swingweight fitting for people who still feel good in a range of 3 or 4 different swingweight?
    Many thanks again for your help and for your way to explain technical golf features that makes it so interesting to all of us,

    • Daniel
      it’s possible to use highest ball speed as a way to determine if the swingweight of the club(s) is right for the golfer. There really is no other way to finalize the right swingweight other than to have an experienced fitter make a judgment for a swingweight the golfer should begin his testing with, and then to slowly but surely do test hitting with the club, hitting shots, adding a little weight, watching the results, asking the golfer for his perception, and continuing this process. There is no device or machine or other method that can do this because weight feel for each golfer is individually subjective and qualitative.

  139. Hi Tom,
    I have my Sterling Iron set now for a little over a week and have played 4 rounds. They are a perfect fit for me. I’m 83 years of age and a 13 Handicap. The high loft clubs check up well and fly the same distance of my old high lofts.The 5, 6 & 7 irons are solid, the best feeling irons I have ever hit. The 5 iron I can count on 155 to 160 in distance. I received my 5 hybrid yesterday and played with it today. It is outstanding. Great off the ground and really good off the tee. Looking forward to a single digit handicap if I can putt as well as I’m hitting the Sterlings.
    Fred Meyer

    • FRED
      Thanks SO MUCH for sharing your experience with the new Sterling irons! WE’re so pleased to hear that you really like the clubs !!!

      The VERY BEST to you in this great game !!

  140. Early results with Sterling irons: My Sterling heads came in last weekend and I built them up. I had a Sterling PW and 5I from an earlier order so I had already experimented with different shafts; I ended up matching what I had in my previous 8I – lightweight graphite built to 37.25″. (I use a 10-finger grip which encourages a slightly longer shaft). I used TWGT S2S White, S Flex, trimmed 2.5″ at both tip and butt. I carefully matched the weights with lead. The lightest one was 272.6 and the heaviest was 275.5. The dead weights of all the clubs are within +-0.5g and the MOIs are virtually identical. Having them all the same length makes the build-up a lot easier.

    So far the results have been great. I’m hitting more greens than before (3 handicap). I missed a few times to the right, and when I carefully checked the lie angles, found that the 2 clubs I used for those shots were 1 degree flatter than the rest. Easy to correct!

    The short irons are maybe 5 yards longer than my old set. The 5I is about 10 yards longer – which is good because I used to have too big of a gap between my 5I and my 4 hybrid. The 5I ball flight is a little lower than I would prefer so I may add a degree or two of loft.

    I have to say I haven’t warmed up to the Sterling SW. It’s okay for full shots but not great for finesse pitches. For the short pitches from a variety of lies, I much prefer a heavier head with a wider sole and more bounce. I see why Tom almost didn’t include the SW in the lineup.

    I already have 3 committed orders for Sterling sets based on people having tried out mine in the last few days.

  141. Dear Tom,

    Thank you very much for your contribution to the golf in general and for game improvement in particular.

    I am a French man of 66 and for various reasons my swing speed is very low (165 yards with a 15,5° Big Bertha driver) and it is not going to improve in next few years. My index is around 15 only because I play straight.

    Two years ago, I bought from your local clubmaker a series of High COR irons 870 Ti for which I replaced I5 by an H5 and still have little difficulties to be consistent with the I6 (I also have a w3 Wishon 949 MC which I replaced by a Wishon 925HL).
    As I strongly believe in the SL concept, I have reserved beginning May a complete set of 8 Sterling clubs (Sw to H5) without having had yet the opportunity to test them (I will only be able to do it in July).
    But now, when I read some comments on your Q&A and Blog Website, it seems that, with such a low speed, I may suffer reduced distance gaps, not only with Sterling H5 and I6 but also, may be, with I7.
    Therefore my questions are as follows:
    1) My 870Ti irons are already HiCOR and have already a variable face thickness: then, what can make the Sterlings I7 and I6 play as long as my 870Ti, since the technologies used for gaining distance seem to be the same?
    2) If I have two clubs (I7 and I6) in the middle of my series of height clubs ordered that do not meet my “equal-gaps” requirements, what should I do: reduce their lofts, enlarge their shafts, replace them by Hybrids, or is there another way that I can use to make them play further ?
    3) If I had to replace I6 and I7 by hybrids, what Wishon hybrids would you recommend me?

    Many thanks for your help,


    • I am also 66 and have a slow swing speed like yours. I had high loft hybrids made recently of the 730cl series with the Ruby lite shaft, namely the 5H (30 degrees), 6/7H (36 degrees) and 8/9H (42 degrees). I hit these well, just as accurate as any iron I have hit and get a nice 10 to 12 yardage difference between clubs. You might want to consider the 730cl hybrids instead of irons.


    • Daniel:

      I’m glad you were able to read some more of the information we provide to help golfers make the best decisions for their equipment needs – especially in the case of the Sterling single length irons. yes, it definitely sounds like you should not include the Stelring #5 iron and most likely not the #6 either. These two irons have lofts of 23 and 27 respectively and those lofts need a little more ball speed to get the shot to fly high enough to carry a proper distance. I think you would be fine with the #7 to wedges if you choose to use the single length set. For the clubs above the #7 iron, I would suggest a 27* loft #5 hybrid, and at closer to a normal 5 iron length – 37.5 to 38″. Then above that a 24* #9 wood at around 39″ in length. Then above that probably a 19* #5 wood or a 20* #7 wood – at around 40.5″ length.

      You should hit the Sterling #7, 8, 9, PW, longer than you hit the 870Ti 7, 8, 9, PW because the lofts of the Sterling are a little lower. Sterling #7 is a high COR face design like the 870Ti – Sterling #7 is 31* loft and 870-7 is 34* loft. Sterling #8 is 35* loft and the 870-8 is 38* loft. Sterling #9 is 40* loft while the 870-9 is 42* and the Sterling PW is 45* with the 870-PW at 46*. Then the two gap wedges are the same loft at 50*.

      I hope this helps, thanks so much for your interest,

  142. Not sure if this is an easy answer but if you took your PCF wedges and used led tape to make them all 300 grams like the 56, is there an easy calculation to determine what length you would build the wedges too so that they would have the same swingweight?


    • Austin

      In clubfitting and clubmaking, you never change the lengths of clubs just to allow the head weight, shaft weight and grip weight to make the clubs be the same swingweight. You choose the lengths based on the fitting analysis of the golfer to determine what lengths are best for the golfer’s height + arm length + his sense of comfort over the ball. Then you choose the shaft on the basis of the golfer’s swing speed + his downswing transition force and point of release – again a FITTING decision. And the grip is chosen on the basis of what texture and size is most comfortable to the golfer. Then you decide what swingweight is best for the golfer based on the analysis of his swing tempo, timing, rhythm and his personal sense of feel during the swing for what feels too heavy vs too light.

      Then you build the clubs to the specs you determine are right for the golfer. All of our head models are designed with an internal weight chamber that can accept up to a 9 gram weight plug – this is what the clubmakers use to establish the final swingweight they need for the clubs. Again, you never want to just take the heads and try to make them odd lengths just so the swingweights can be the same.

      Hope this helps,

  143. Interesting concept but how about single length fairway woods.

    • JOHN
      It could be possible to combine fwys and hybrids to all be single length so you could have two single length segments in your set. You see, one of reasons that single length in irons could be beneficial is that depending on how many irons/wedges you choose to use at the single length, you could have anywhere from 5 to 8 irons all with the same identical swing feel, perfectly duplicated in every element related to swing feel. That means during the course of a round you probably would hit as many as 18 full swing shots with the irons. Which means you could have as many as 18 shots swung with the same precise swing feel.

      Over time that can build up to help you groove your swing a little better to get to that point of better shot consistency with the irons because you are getting more shots with the same exact feel. More repetition with the same exact swing feel in other words.

      If you just make single length fwys, one drawback is going to be the fact that most golfers don’t have more than 2, maybe 3 woods in the bag. But most golfers don’t hit those woods more than 4, 5, 6 times over the course of a round. So in terms of this “more repetition” with clubs of the same identical swing feel, you won;t get that nearly as much with the woods as you can with single length irons.

      But if you combined the woods and hybrids to all be the same length, then you increase the number of clubs above the irons which you can make to have the same swing feel. From that you could increase the shot repetition to be grooving more swing consistency with a combined segment in the set of single length woods + hybrids.

      it’s a possible in other words, but I think it has to be done by combining the woods with the hybrids at one length for all.


  144. Hit these irons yesterday as a demo…I’m in! Ordering my new set today from a local fitter. On good swings the clubs feel great, very good short game feel, forgiving and provide good feedback, no distance loss on any club. The wedges, I feel, will take the most time to get used to, but even that won’t be long. They’re not magic of course, you still put a good swing on the ball, you’ll be rewarded if you do and the irons will help you out if you don’t. The set up is easier, more consistent. I’ve been playing Mizuno MP 32 and MP58 (back and forth and usually a mix) looking forward to making the switch.

    • Thanks Kevin, we’re very pleased that you like the test hitting you did with the new Sterling irons! Much appreciated and the very best to you in this great game,

  145. Tom,
    I am happy to report I am purchasing the Sterling irons from your club fitter Michael Clark in Berkeley CA. I want to thank you for researching the past few years in designing the Sterling head to eliminate the distance gapping problem for single length shaft lengths. It opens up the single length club to retail golfers like me.
    From our previous emails, since I have slow swing speed, I need any equipment technology to help me hit a higher trajectory. My question is do you think I should have the Aerotech 70 gram steel fiber 36.5″ shafts trimmed to its lowest possible kick point for a higher trajectory and not have them trimmed to a standard 8 iron trimming?
    Thank you,

    • ROBERT
      I am pleased to hear that you did get the chance to meet and work with Michael ! For your question about the shafts and trimming, this is a question for you to discuss with Michael and not with me. To answer this correctly for your best needs, the person who fit you and saw your swing has to be the one to make this decision. I could not do that because I have no experience seeing you swing and hit shots. So please do pose this question to Michael.

      Thank you,

  146. Tom

    Your Berkeley fitter Michael Clark was great! We figured 36.5″ is the proper length for my new set of Sterling Single Length irons. I ordered the 5 hybrid due to my slow club head speed. I can hardly wait to be playing my new Sterling irons as they won’t arrive until about mid June in Durango…
    Thank you for doing your in depth research to produce high fidelity single length irons!

  147. Tom,

    Thanks for your great input! Today I scheduled and appointment with your long time friend Club fitter Michael Clark, in Berkeley, CA. We are meeting this evening. I’ll keep you posted…

    • Great to hear Robert ! Please be sure to say HI to Michael Lee on behalf of me when you see him.

  148. Tom,

    I have been using Moe Norman’s single plane swing for 3 years now and am a true believer that it is a better swing than conventional golf swing teaching. I am a senior and now swing the driver on average 78 mph and am a 15 hcp from tees 6000 yards or less. I have broken 80 twice in the past 3 years. I currently swing senior graphite shafts and play Ping G 30 irons which I like because they help me hit a higher ball with slow club head speed.

    I am extremely interested in purchasing your Sterling single length irons however am afraid they are for players who have higher club head speed and I would not be able to a high enough trajectory. I would like to stay with graphite shafts for its light weight and vibration absorption for my old muscles and bones. Do you think the Sterling single length irons would be appropriate for my club head speed and graphite shaft need?

    Thank you

    Robert (A 45 year golf player)

    • ROBERT:
      The days of most golfers actually using all irons in a conventional set of incremental length irons are gone. VERY few golfers have the swing speed and swing skills to hit an iron with less than 25-26* of loft and should be honest to say no I won’t include that in my iron set and I will choose hybrids or high loft fwy woods of more conventional hybrid/wood lengths for those distances. From what you say about being a 15 with a driver speed of just under 80, you should think to start with a #6 to wedges in the single length set. Then you choose the clubs above the #6 iron on the basis of perhaps a 23-24* hybrid of around 38″ length, a 5 wood of no more than 41-41.5″ above that.

      I always design every head model with additional weight addition capability so that every model I make could be fit with any shaft that fits the golfer – graphite or steel. choice of the shaft has nothing to do with the head design, it is all about fitting to the golfer’s swing speed and swing characteristics of transition force, tempo, point of release.


  149. Hi Tom I have a set of sterling irons and absolutely love them. First round out with them I hit 5 approach shots over 140 yards within 5 feet. I dont know the last time I did that. I have the 5-sw and would really be interested in matching a 4 hybrid to these irons. I know there is a 5 hybrid to replace the 5 iron but im wondering if u will be making something like an 18-20 degree hybrid for this set and how it would play at the 36.5 inch length.

    • Kourtney
      Thanks so much for taking your time to share your experience with the new Sterling irons ! Very pleased to hear you like them and that they are “behaving themselves” for you !!

      If we do a lower loft head to add on to the set, we most certainly are going to recommend/insist that the golfer have a clubhead speed of at least high 70s to 80s and higher with the 5 iron before they consider adding the iron of lower loft than that. At the 36.5″ length, your clubhead speed is a little bit lower than it would be at a longer length. That has an effect to make it a little more difficult to get shots hit with low loft heads to fly high enough and with enough spin to carry properly for distance. For most players, using a conventional hybrid or fwy wood above that 5 iron would be better – such as a 3 hybrid of say 38-39″ length or a 7 wood at not more than 40-40.5″ length.

      thanks much!!


  150. Tom, thank you so much. I truly appreciate your reply amd your taking the time to answer all of us, no matter how simple or in depth our questions are. Im really looking forward to a demo and fitting.
    This concept is really appealing due to the fact that i have a broken collar bone on my right side that never healed, and consequently gives me a two inch reach. It takes work to keep that side quiet..By the way, as I already have steelfiber.370 shafts in my VR Cavitys, can i use those in the Sterling heads or is this an issue?
    Thank you again,

    • SHELBY

      My pleasure for sure! If the single length set is being made to a 36.5″ (8 iron) length, then every shaft in each iron has to be tip trimmed and installed like it is an 8 iron. If we assume that the Aerotech shafts in your current set were properly tip trimmed for each different iron, then you should be able to cut 1/2″ more from the 7 iron shaft, 1″ more from the 6 iron shaft, 1 1/2″ more from the 5 iron shaft and then you could install these in any iron in the single length set. BUT . . . . and this is a big one, this will not ensure that the final length of the irons would be 36.5″. There are differences between all the different iron models out there with regard to the hosel length and the bore depth. This is what determines how long the clubs will be when a shaft is tip trimmed and then installed. So it would be best to take your 8 iron shaft first – remove it from your current 8 iron, then clean up the tip and test install it into the Sterling 8 iron head – measure the length to see how this stands. If you find the length is shorter than 36.5″ in the Sterling head, then you have to use an extender in the shaft to bring it up to proper length because you know your current irons are made with a hosel length/bore depth that puts the shaft tip closer to the ground. If you find the length is longer than 36.5″ when the shaft is test installed in the Sterling head, then you cut off what you need from the butt end to bring the club to the 36.5″ length. And then you follow the same procedure with the other shafts after tip trimming more from them to make them all an 8 iron shaft tip trim.

      Hope this helps,

  151. Tom,
    Im very excited about these and saving my lunch money..
    I currently play Nike Victory Red full cavitys with steelfiber i80 shafts.
    8 iron is around 145 and i have a great instructor, Tom Perry, in WA state.
    It seems i am having a difficult time finding a place to demo these..any suggestions for the greater Seattle area?..or Bellingham?
    How do the wishon graphite shafts compare in your opinion to the i80, if its possible to do that?

    • SHELBY

      In the greater Seattle area, I would strongly recommend Jim Von Lossow of Von’s Golf Shop. I know he has sets of the heads on order, but you’d want to call him to find out if he has any demos yet or is soon to have them. Jim and I go WAY BACK in this industry together – we both started out in the PGA in Northern Cal before I went my way into engineering and design and he got hooked on being a clubmaker and clubfitter. he’s VERY good. 206-406-2619 or jim@vonsgolf.com .

      Thanks much hope this helps,

  152. Hi Tom,
    Anywhere in Ireland that these can be demo’d. I am away in South Carolina this summer either if there was someone there you would recommend.thanks. Dave

    • DAVE

      Not at present – sorry about that. perhaps by mid summer as we catch up and can then bring the UK into the picture. But also, there never have been all that many independent custom clubmakers in Ireland for whatever reason I do not know. about the only one I know of is The Golf Studio in County Kildare on 627 9811 or 087 625 847, or email at


  153. Tom I’ve been buying your stuff and reading your articles for at least 10 years, maybe more. Anyway, I’ve recently read just about everything you’re published around the SL iron project and I’m anxious to get some demos to experiment with. Conceptually why wouldn’t you want to have the same swing from iron to iron if you can eliminate the downsides? It seems you would.
    The industry is struggling with how to make the game easier for the average person, and this could be something that aids that. If it works, and is accepted, it could really change the industry for amateurs. Even if it mostly works, if it generates enough interest, the concept can be refined over the next few years to eliminate most of the pitfalls.
    I noted your perspective on the game being rooted in tradition, and it reminded me of something similar. Back some 15 years ago Golfsmith introduced a set of snake eyes irons where the 3,4 were replaced with what today are called hybrids, and then the 5-7 went progressively from hollow designs to solid in the wedges. They also tweaked the lofts and club lengths to 3/4” in an attempt to solve the distance gaps. It was actually an amazing set of irons and way ahead of its time. My uncle is still using them! After just two years Golfsmith stopped making them because they didn’t sell to your point about tradition, but here we are 15 years later and hybrids are now being offered as standard replacements for 3,4 in most sets.
    My point is that rarely does a new product like this reinvent the market on first launch, but hang in there you may just have broken through on something that changes the game forever in the long term. Think about gaining experience and tweaking this just a bit over the next few years and I’m sure you can achieve the best of both worlds. If we see the big boys start offering these then we’ll know you’ve hit a nerve, Best of luck with the new design.

  154. Thanks Tom for the quick response!

    Could someone put a graphite shaft in the 5 and maybe iron to promote club head speed and ball flight and leave the other irons with your Wishon superlite shaft or whatever shaft fits them best?

    I know that would in fact slightly defeat the purpose of keep all the clubs the exact same specs, but would it help get the lower irons off the ground? Is the fear there that your yardage gaps will be too great?

    Also, what swing weight did the sterling irons come in with your superlite steel staft in stiff flex cut at 36.5 inches and a normal 50 gram grip with the 274 gram head?

    Thanks again!

    • LANDON
      One of the things we did a LOT during the testing of the Sterling irons was to change shafts to watch for the effect on shot height. Bottom line is that you could drop two full flexes from what would be your proper fit shaft and it would have virtually no effect on the height of the shot at the 8 iron length of the Sterling irons. The reason is because, 1) iron shafts already are stiffer than wood shafts of the same flex by a lot – during the actual swing, an iron shaft bends half as much as does a wood shaft of the same letter flex. 2) the shafts used in a 7 or 8 iron are stiffer to begin with by a good bit more due to the normal tip trimming performed on the shafts during installation. They need to be this way to offset the bending effect of the head weight being higher in the higher number irons in a conventional set.

      So when you combine these two things, there is very, very little that can be done to make the shot trajectory higher for irons that are either 36.5 or 37″ in length. The solution for irons that a golfer cannot hit high enough to generate max carry is to not even have them in the bag, and to replace them with hybrids or high loft fwy woods which are of lengths which fit the golfer’s swing ability.

      Starting swingweight for the 274g head with 50g grip and Superlite steel shaft at 36.5″ is C7.5 to C8. As with all of our head models, the Sterling irons do have our hosel weight bore which allows the addition of up to a 9g weight plug during assembly if needed. The starting swingweight for the 274g head with 50g grip and STEPLESS steel shaft at 36.5″ is D0-D0.5, FYI.


  155. Tom

    Tom Miller at Par Golf in Raleigh, NC fitted me with a set of your 771’s a couple of years ago which are really great irons. I frequently access your site to review your updated comments and videos and have been following the comments on your new Sterling SL irons which have really peaked my interest in the SL iron concept. I was able to schedule a session with Tom M. this past Tuesday to try them out and was more than pleased with the results. I was able to hit 5, 7, 9 and PW in 36.75” shaft lengths. As a reference point, my current 8 iron length is 37.25” and my average mid iron swing speed is around 70 mph. I am a 17 handicap senior player. Prior to my session, I was a little concerned that I would lose too much distance with the 5 and 6 irons and that the feel between the 2 different head designs would be difficult for me to adjust to. Frankly, I was surprised at my results. Once I got over the brief oddness of swinging such a shorter length 5 iron, I found that I was hitting it the same, if not with a little more distance than my current 5 iron which has a high COR face. I believe this is because I was consistently hitting the SL 5 iron more on the sweet spot with consistently improved tempo compared to more inconsistent sweet spot hits with the longer shafted 5 iron. I hit about a 110 balls switching frequently between the different SL lofts, and the more I hit the different lofted irons, the more they felt the same, which I understand is the concept of SL irons. What I also noticed was my shot direction and dispersion were very consistently better than with my traditional length clubs, especially with the 5 iron. More GIRs is what I need to improve my scoring and I believe your Sterling SL Irons will help me to achieve this. To this point, I placed an order with Tom M. before I left Tuesday and look forward to their arrival.

  156. Tom, What is the expected price range should I expect to pay for a set of these Irons?

    • GENE

      Thanks much for your interest! The custom clubmakers who fit and build our designs for golfers are all independent business people, not tied to us or to any supplier with whom they do business. So they set their own prices for the services and custom fit/built clubs they offer. You’d want to find a clubfitter in your area, then contact him to ask about pricing. But I can give you an estimate that an 8 pc set from #5 to SW with graphite shafts should range somewhere between $1000 and $1200. The Sterling heads are all a soft carbon steel body with ni cr plating with the 5, 6, 7 iron heads being a high COR design. So the construction is a more expensive design to create than other conventional cast stainless steel iron heads. But this is how we can create the set at a shorter length than others and still have it work from a proper distance standpoint for golfers.

      Thanks again,

  157. Hi Tom!

    I have been waiting for the day when a single length set came available! I am a huge fan and love to tinker.

    I saw in an earlier post you discussed the potential lack of club head speed for the lower irons due to their short length. Hence why there is no 4 iron in the set. Could that could effect ball flight on a slower swinger?

    I hit my driver at 92 miles an hour. I am not sure how that computes to an 8 iron length. (36.5)

    I am hoping to hit a variety of shafts when I get fitted for these clubs, but if a graphite or lite steel shaft is a good match for me is their concern that the swing weights could fall below D ?

    I love the stepless steel shaft that you carry but that is around 117 grams and am hoping that weight won’t impact my swing speed.

    Your thoughts ?

    Thanks so much for your time


    • LANDON

      Thanks very much for your interest!! The only consideration that clubhead speed has in working with single length iron design is its effect on what would be the lowest number head you would have in the set. As the golfer’s clubhead speed gets lower, his ability to hit the lower loft irons high to fly well is tougher. Which means you skip those low loft iron(s) and use conventional iron length hybrids above that, or high loft fwy woods built to not be too long.

      Where a player might consider using 37″ over 36.5″ for the single length is if he really wants to have the lower loft irons in his set but knows that perhaps at the shorter length his speed could be just lower by enough to make hitting the low loft iron high to fly more difficult. But if the player goes with a 37 to try to make it easier to hit the 5 iron let’s say, then he has to think long and hard about whether the 37″ length could make it a little tougher to not hit the high loft irons too far or with less accuracy. It’s a little bit of a balance.

      In the end, I think it is better to go with the shorter length unless you have always played +1″ longer irons due to your height and a longer wrist to floor measurement. With the 36.5″ length you get a little better chance to hit the lower loft irons more on center more often, while at the same time the 8, 9, P, G irons are not so much longer than they could cause a distance and accuracy issue. And you get honest with yourself and tell yourself if you can’t get the 5 iron well up to fly, then you go with a 6 to wedge single length set and you use normal hybrids or high loft woods above the #6.

  158. I noticed Gary Baliett in Chandler AZ as one of your fitters. Can he custom fit and make a set of Sterling clubs for me? If so, how do I get in touch with him?

    • Mr. Turner

      Absolutely – Gary’s phone # is 602-931-2653 and his email addresses are 1) or 2) I know that he does have several of Sterling single length sets on order so he is well aware of the new model in his work.

      Thanks very much for your interest,

  159. Dear Tom,
    I live in Japan and really want to get the Sterling SL iron set as soon as possible. Is there any shop in Japan or website where I can order it? (I tried to order it in, but they seem like they don’t ship to Japan.)

    • OT;
      Thanks very much for your interest in the new Sterling irons AND for also asking us about availability to Japan. The website will be set up to ship internationally, hopefully very soon. Just this last week the web programmer finally got everything set up for handling the domestic US orders and now he is going to work on getting the program all set up to enable international shipping of the clubs. I do not know exactly how long this is going to take, but I have to believe it will be OK for international orders within 1 week, hopefully not more than 2 weeks. So if you just wait a little bit of time, then check back on the site, it should be ok soon.

      Thanks so much again for your interest !!

  160. I’m coming from Ping G25, so I’m interested in playability rating of the Sterling Single Length Irons. Are they super game improvement? Ultra? Game improvement? What are the clubhead sizes when compared to the Ping G series?

    • JIM
      Thanks much for your interest. I’d say if I were to rank the Sterling irons, they’d be in between game improvement and super game improvement. Although in saying that, I know there are a number of very good players using the design – one clubmaker told me last week he has a player who is using the Sterling in US OPen qualifying on May 11 at Bethpage, and we got an email last week through our website from a former Clemson Univ golf team member who still plays very well and loves the irons, and also happens to be the nephew of Billy Joe Patton – pretty strong good player pedigree there!

      Features that make them a GI to SGI could be, 1) the head shapes are slightly larger overall – if you are looking for a compact forged blade type size for the heads, that’s not the Sterling. 2) the 5, 6, 7 are a high COR thin face design to generate the proper distance at the shorter 8 iron length. Any high COR face iron seems to be pigeonholed into an SGI category. 3) But then the body of the 5, 6, 7 and whole head of the #8 to SW are a 1025 carbon steel body design so that part pulls things a little back from the SGI category – but with a deep back cavity that puts them in a GI category.

      I’m sorry I can’t answer your question about the PING G Series or any other iron model in comparison – I never touch or look at any other companies’ club models – we don’t have any big golf stores in my little town in the SW Colorado mountains that I would walk into to look at any other models, and when I am in the pro shop of any of our courses here, I never look at the other clubs. I’m sorry, it may sound weird but I really have never had any interest in what any other companies do in their design work so I rarely ever see other models of clubs.

      I’d say you just need to search for a clubmaker who will eventually have the Sterlings in his shop, head over there and take a close look and hit a few shots to see if this could be for you. If you need any help in seeing if there is a decent clubmaker anywhere near you, send us an email at and let us know your town/city and we’ll respond to let you know if there is a good clubmaker you can contact to ask when he will have his Sterling heads for you to see.

      Thanks much,

  161. Dear Tom,
    I live in Thailand, and have been following your work for quite some times, please advise if you have anyone distributing your Sterling SL iron here in Bangkok Thailand, am very interest to try it out and may have it custom fit.

    • RICK:

      Yes, there is a clubmaker in Bangkok who has been custom building with our designs and with whom I correspond about technical matters so I am aware that his level of fitting knowledge is pretty darn good. His name is Navin Wangyuruey ( . His business is called Sweet Spot Fitting Studio and he works from the North Park Driving Range. his phone number is 8 4554 6419 and he has additional information at

      One little bit of additional info – we’re just now starting to ship Sterling heads to begin filling the orders of the clubmakers that began to hit us way back in late January. So not that many of the clubmakers have their demos, test clubs and inventory in the Sterling irons. You’ll want to call or email Navin to ask him when he might be getting his demos in before you go see him.


  162. Hello! Interested in building a set of these irons in 5-PW but wonder how to complete the rest of the rest. Would it be possible/would you recommend porting (I think that is what it is called, drilling the holes in the back of the wedges) your Micro groove wedges so that they have the same clubhead weight? Easy to bend them to the same lie angle if so than and I could make a 5-60 all one length? If so, do you offer the porting service?

    Also, already use the 18 590DIH and love it. With the lofts on the single length 5 iron being so low, do you think adding a 21 degree 590DIH would achieve a good gap between those two clubs? I’d build the 18 and 21 identical by using a little lead tape but I’d probably make them both more around the length of a traditional 4 iron.

    • AUSTIN
      When it comes to the SW and LW, there is a split in how golfers are approaching these scoring clubs within the context of a single length set. Some are of course doing the SW at the same single length and specs as the rest of the irons. Others see their SW and LW as separate, standalone clubs that they are leaving as is, particularly if they do really like their present SW and LW, if they have one. The reason this is an option is because the SW and LW are not primarily full swing clubs as are the other irons, and even as is the PW and GW for many golfers. Sure, we chip with the PW and GW, but we also hit more full swing shots with these two than we tend to hit full swing shots with the SW and LW. Thus it can be said that while many can see a benefit in having the Sw at the same single length specs of the rest of the single length set, it can also be said that when the SW and LW are used chiefly for a variety of less than full swing shots, it is ok to keep them at their previous, preferred specs. And then focus on the other irons through the PW and GW as single length with all swing feel elements matched identically.

      For the clubs above the single length irons, you approch those just as you have in the past. whatever your lowest loft iron is in a single length set, add 10-15 yards to that full carry distance of that iron, and go look for the hybrid or high loft wood that allows you to achieve that distance. Next after that, add 10-15 yards and do it again for the next hybrid or wood up from the lowest loft iron you select.

      Single length has not yet been seen as a possible with the hybrids and woods – it may turn out that way with a bunch of work to determine what lofts with what single length works while NOT robbing the golfer of distance. but not yet.


    • Thanks Tom for the incite. If I did want to try making the 56 and 60 at the same length. Would Porting the wedges as I mentioned be a option to get the heads at the right swingweight? I have no idea how much material would need to be removed to achieve the proper swingweight. Thanks!

    • Austin
      Any time you need to remove weight from a wedge head, if you can’t do it by grinding it off the sole and the back, then you have to drill holes in the “fattest” areas of the head. In general, for each 2 grams you take off a clubhead, you reduce the swingweight by 1 point from what it was. On average with a steel head, a hole of 1/4″ diameter X 1/2″ deep will remove 2.5 grams of weight.


    • Thanks Tom, so do you think it would be possible to take enough weight off the PCF Micro wedges to get them to the 274 gram weight of these irons heads? Have a 5-60 same length set really intrigues me…thanks again!

    • Austin
      Probably not that hard to take the 52 wedge down to 274 because that would be around 10-11 grams to remove. Porting on the back flange could be done to get that off the head. But not on the sand wedge and no on the lob wedge. SW spec weight is 300g so you’re talking about 26g and that’s a lot to ask for. LW spec weight is 295 and 21g is also too much to hope to remove and not mess up the head.


  163. Since the 5hybrid is +- 4* would it be possible to make it the next club after your 5 iron? For example if I hit the sterling 5i 195yards and make the 5h -4* to 19 could I achieve enough gap to hit it 205-210yards? Does it come down to swing speed? I’m guessing so but correct me if I’m wrong. If this is possible I would love to have the 5h in my arsenal. Really looking forward to getting my hands on your great product Tom!!

    • ANDY
      We do not use the bendable hosel on our drivers, woods and hybrids to change loft. On those clubs with wider soles which are traditionally SOLED in the address position, the bendable hosel is used for changing and fitting lie angle and face angle, not for loft.

      Technically it is possible to bend the hosel of the hybrid for a loft change – BUT . . . if this is done the golfer always has to remember to never sole the head and to always turn and hold the face square at address, hovering the clubhead off the ground in this position. While that could be done, not all golfers would be able to adapt to that – hitting a shot consistently solid while hovering the clubhead a little bit above the ground. Not to mention when you do this with a hybrid, you change the sole angle so when the head is hovered above the ground held in a square face position to achieve the loft change, the sole is not parallel to the ground anymore. That can cause a digger shot or bouncing the rear of the sole off the ground before contacting the ball.

      With our hybrids, we can measure through our inventory and hand select heads which might be +1/2*, +1*, -1/2* and -1* from the designed loft of each hybrid. ALL heads, no matter the company, are made with a +/- tolerance for all the specs of the head. So we can if we measure enough heads, find a hybrid #2 with 19* loft because the spec loft of the #2 is 18 so the 19 is within the +/-1* tolerance. But if you tried to bend a #4 from its spec loft of 24 down to 19 and then hold that face square after the bend to get the 19* loft, the leading edge of the head would be so angled downward that you’d be very hard pressed to not hit real pronounced digger fat shots most of the time.

      Hope this helps because it is a fact related to bending drivers, woods and hybrids.

  164. Is there a limit the USGA puts on COR for irons? If so do these Sterlings comply with tournament play? I’m very excited to take some swings with these! Great job Tom, I haunt hit these yet, but I think these are going to be winners.

    • ANDY
      Yes for sure, all clubheads from driver to wedges have to conform to the USGA’s COR limit of 0.830. When the USGA sees a model could be a higher COR design, they do certainly include the COR test as part of the overall conformity test. So yes, in the official ruling we got several days back saying the Sterling irons are conforming, this means they are conforming for every element in the USGA rules.

  165. Do these SL irons conform to the 2010 USGA groove rule change?

    • Andy

      yes, the Sterling single length irons are officially conforming to the USGA and R&A Rules of golf which includes the 2010 groove rule change. If they are not currently on the USGA’s web list they will be very soon. Under the USGA’s records, the Sterling conformity ruling is #2016-215A-H .


  166. Tom: Would you recommend these Sterling clubs for the high handicap people like myself with slow swing speed <80 mph, or would the 730CL line be a better fit? For myself I hit my driver down the middle of the fairway very consistently, but only 150 to 160 yards including the roll. Also 6 hybrid 110 to 110 yards.


    • Jerry
      it is a fact that with single length as well as any conventional set of irons, the slower the swing speed, the fewer irons the golfer should have. At your speed and distances I would say not to have an iron lower than a 7 iron. Then to have either high loft woods or hybrids or more normal iron type length above that 7 iron. Even with having the set be 7, 8, 9, PW, GW the golfer still has 5 irons of precisely the same swing feel so the potential for more consistency can still be there – of course providing the fit of the irons for the best shaft weight, flex, total weight, swingweight, lie and grip size is done for the golfer.


  167. Tom
    I done a fitting on a DR. from ECU the other day that had taken lessons from Moe Norman a few years ago. When i saw him swing it was just like watching Moe.
    During the fitting we came to the conclusion that 36.75 and 2,25* up fit him perfectly.He was very pronated causing the more upright lie angle.

  168. Hi Tom, do these have a forged feel? what handicap are these best suited for?

    I currently have Mizuno JPX850 forged irons and am wanting to go to a smaller better “feeling” iron. Would these fit the bill?

    • Shelby
      Thanks much for taking your time to post and ask. Because of the thin, more flexible face of the 5, 6, 7 iron coupled with the carbon steel body of all the heads, they do have a softer impact feel than a nomal 1 piece cast stainless steel iron. BUt they are not small and compact in size like a typical forged blade – they’re mot obtrusively large either because I don’t design like that, but they are not small.

      Single length is an assembly concept. it is NOT a head design. As such, just like you have all types of iron head model types in conventional assembly irons, if single length were to catch on enough, a company would want to create different model types for single length assembly – blade, compact cavity, game improvement cavity, super game improvement, etc and on. Best thing I can suggest is to use our Find a Clubfitter search tool on our website to see if there are clubmakers in your area who have or who will have Sterling demos for you to see and test hit before you ever go a step farther. We’d never want any golfer to not try before they buy when they have some reservations and questions about the look or feel of a model.


  169. Am a 6 handicapper,7 iron ss of 86mph last time measured. Really like the concept of having one length of shafts. My current issue is I struggle for control in my longer clubs and it gets worse at it gets to the driver. Have shortened the driver down to 43″ to try and help control. I am a bit worried that if my longest iron is say 37″ the gap in terms of length to my hybrid/fw/driver gets bigger and makes them feel even more different and hence improving iron consistency comes at the cost of reducing driver/woods consistency. Any thoughts the impact of playing a one length set of irons has on the woods?

    I definitely like the thought of having longer shafts in my shorter clubs, especially for pitching etc. I am 6ft5 and have never felt comfortable with the length or weight of a wedge relative to a middle iron. I guess the concern is that I already hit my wedges further than I would like and this could be magnified by the longer shafts

    • STEVE:

      What we teach for the fitting of the clubs above the lowest loft single length iron is this – find out what the golfer’s consistent carry distance is with the lowest number single length iron. Add 15 yds to that and then go out and find what combination of loft + length in either a hybrid or a high loft wood will achieve that distance. Once that is found, add 15 yds to that club and go about the process again to find the next club up. And so on up to the driver. It’s really a lot easier than you think it is.

      In your case with a 7 iron speed of 86mph, you do have plenty of clubhead speed to be able to properly hit the 5 iron in the Sterling single length set high enough and with enough spin to get its full distance and to give you what more than likely would be a little bit more distance than you currently have with a normal 38″/26* loft #5 iron. So once you would know what your carry distance would be with the Sterling #5 iron, then do the exercise of add 15 yds, then go find the hybrid or wood that hits it that distance without it being inordinately long.

      As of yet, the prospects of looking at fwy woods or hybrids as single length clubs is possible for some golfers, not for all. A lot more work has to be done in this area. In general, it’s going to be potentially more possible to do this for slower speed players who would need to have fewer irons and more hybrids or woods than it will be for higher speed players who would not have nearly as many hybrids or woods in their set. Single length works best when the “segment of your set” has more clubs so more clubs all can have the same swing feel. LIke irons, you would have 7 or 8 clubs so having that many clubs all of the same precise swing feel is a benefit potentially for shot consistency.

      If you only have two hybrids or two fwy woods, there you have a situation where so few of the same kind of club would allow the same swing feel effect of single length to do its thing as well.


  170. Do your one length irons come I left-handed models?

    • William

      Many thanks for your interest. I am sorry to say that right now, we have not yet tooled up the model in left hand. We’re a small engineering based company so we need to see that the right hand initial model can be successful and have staying power before we invest in the dies and inventory production to offer it in left hand. No left hand model of any club design has ever sold more than 8% of the units it will in RH so unfortunately that creates a pair of handcuffs of sort that we have to watch before we can make that move into LH. Maybe by later in the summer if all goes well.

  171. I Just received my two demo sets of the sterling SL and i assembled an i5 at 36,5 inch and the same moi as my regular 560MC i8 and went to the studio.

    Just after hitting 30 balls i have to say i am super thrilled about these irons and i am glad that i convinced some of my customers to wait and try these ones out. I even gained distance compared to my original i5 and its never been easier hitting a 23 degree lofted iron.

    Even if your not into SL its a damn good iron and that alone is a selling point.

    i think this will be the model i will focus on getting out to my customers and with the great service i get from peter Qvarfordt at WishonGolf Nordic it will be really enjoyable to build clubs this spring.

  172. Tom,

    I have been playing 1iron clubs for a few years now – have been sold on the single length for quite some time. I’ve been looking to upgrade my irons but haven’t found anything until last week. I’ll be setting up a fitting here soon (your club fitter finder doesn’t have anybody in the Vegas area – would you recommend that I go up into Utah or down into Arizona?). When I was playing with a “standard” set, I found that I was always choking up on my 3 and 4 irons in order to hit them more consistently, so adjusting to the shorter long irons was super easy – getting used to the longer wedges was a little tougher but I really love having one swing for all my irons.

    My go to club off of the tee right now is my 4-iron, am a little disappointed that you are starting with a 5, what was the deciding factor there?

    I read one of your responses about the LW – have to agree there – I find that I leave the LW in my bag most of the time, I usually chili dip it from a tight light and hit it high on the face from the rough…guess I need the bounce on the SW in the tight lie and I usually just open up the club head instead of reaching for the 60 degree wedge. Did you change the bounce any for the SW or leave it the same as the other clubs?

    Looking forward to trying these out.

    • DAN
      It’s unfortunate and amazing as well that there are no certified, experienced custom clubfitters in the Las Vegas area. It’s a large metro area and a good golf town and I would think a good clubmaker should do OK there. I would say if you do get down to AZ that’s where you should go. BUt as well, we’re supporting a new direct fitting operation for the Sterling irons at so that is an option as well. This site is due to go live in a matter of days so you can go there now and register to be notified when everything is up and running and ready to go.

      Regarding the LW and SW, that’s an either or for each golfer based on whether they like and are very used to their conventional SW and LW. Single length poses the most benefit for full swing clubs. The perfect match of the swing feel elements does lend itself to higher swing and shot consistency for full swing shots. SW and LW are clubs that are used far more for less than full swing shots from chips to pitches, to quarter/half/three-quarter shots. So if the golfer is used to his current SW and LW, he certainly can try the single length SW to see, but in the end may be happier with keeping his current SW/LW and going with the single length in all the full swing shot irons.


  173. Tom,
    Loving the new Sterling’s. Every club is 10 yards longer. I am amazed at how well they perform and feel. Low and high loft irons are playing so well. You really know your stuff. I was skeptical but not anymore. My friends are really interested after hearing me talk about them for months and now with DeChambeau’s in the spotlight at “the Master’s” it’s going to be very popular I feel. Look forward to a #4 iron. Thanks.

  174. Will these be available for lefty’s?

    • AIDAN
      Hopefully and hopefully in not too much more time. We’re a small engineering based company so we need to see if the model can be successful and have staying power before we can spring for the investment in the tooling dies and inventory for LH. Never in the golf industry has a LH model sold more than 8% of what the RH version sells, so we have to watch and see how it all shakes out to know if we can make the move into LH. Thanks much for your interest,

  175. Tom, I have the 771 CSI irons built by Ronnie Barnett for me,and love them. In your catalog the 771’s are ranked as the most forgiving of all your iron offerings.Just from the pictures I gat the feeling the Sterlings are less forgiving than my 771’s. Would like to have your comments.

    • Tariq

      The Sterling #5, 6, 7 are exactly the same face design as the 771CSI – same material, same variable thickness face, same face thickness, same COR. So those lower loft irons where the ball is compressed more against the face at impact are exactly the same level of off center hit forgiveness as the 771’s. The Sterling #8, 9, PW, GW, SW are one piece cast 1020 carbon steel deep cavity back so they have very good off center hit forgivenss from the deep cavity back, but they are not variable thickness faces like the #5, 6, 7 and 771’s. At the same time, when the loft increases on heads down through an iron set, both a deep cavity back and a variable thickness face begin to lose their off center hit forgivness a little bit. The reason is because as loft increases on heads through an iron set, the face is tilted back more and more. As the face is tilted back more, the ball can’t compress inward on the face as much as it can a lower loft on which the face is not tilted back as much. So even on the 771’s when you get to the 8 iron and higher, you can’t get the same level of off center hit forgiveness that you will on the heads with lower lofts in the set. hence you can say that while the #8 to wedges in Sterling are not variable thickness and the #8 to AW on the 771’s are, the 771 VTF on the #8 to wedges doesn’t add all that much forgiveness over what happens with the deep cavity back of the Sterling. A little bit more, but not a huge amount more.


  176. Will you have a ladies set available?

    • Barbara
      Thanks very much for your interest. Please bear with me as we do things a lot different than other golf equipment companies you are more aware of and used to.

      For us, we are totally committed to the concept of custom clubfitting for ALL golfers. That’s why we only sell our designs as components to certified custom clubmakers. The clubmakers fit the golfer, determine what all the different fitting specifications need to be for the clubs for each golfer, then like a tailor they custom build the clubs for the golfer using our clubhead, shaft and grip designs.

      In the world of custom fitting, there is no such thing as gender – there is no such thing as “ladies clubs” or “men’s clubs”. There are women whose fitting specs may be for lengths and weighting that is longer and heavier than a man’s custom fit clubs, and vice versa. Other companies don’t see it this way because other companies are in the business to “sell it standard off the rack”. So while the “ladies clubs” from other companies will always be 1″ shorter in length than the men’s models, the clubheads for the ladies sets from the big companies are the same as the men’s except for the difference in color scheme to supposedly appeal to the average woman.

      The Sterling irons can be custom fit to any golfer’s size, strength, athletic ability and swing characteristics. So whether you have a 40mph to 95mph clubhead speed with the irons, whether you are 4′ something or over 6′ tall, whether you are of below or above average strength, and regardless of your swing characteristics, a good clubfitter can easily fit the Sterling single length, or any of our other models, to fit you.

      If you need help finding a custom clubmaker with whom you can work to be custom fit, you can head to the middle of the home page on our website at where we have the FIND A CLUBFITTER search tool. You can input your town/city/zip and see if there is a certified fitter in reasonable proximity to where you live. if there isn’t, because good clubmakers do not grow on trees, then please take the time to send us an email at to let us know there is not a clubfitter in your area and we can explain the options we have to work with you.

      Thanks very much !!

  177. Tom, super excited as I was informed heads will ship later this week. What is your opinion about the feel of the heads in the 5-7 and 8-sw? Which clubs in your current line do they compare to? I love the feel my 560mc and was hoping they would feel as soft as that. Finally, if the clubs are built with a shaft like dynamic gold at 36.5 ” with standard grip what swing weights have you noted in the final build? Thanks again for all your responses.

    • ERIC
      The Sterling heads are all set up at a 274g headweight, which has always been our spec head weight for an 8 iron in just about every other iron model i have designed. so that means at a std length of 36.5 with a std weight rubber grip of around 50g, with a shaft like Dyn Gold you should see the swingweight begin at D0. All heads have our usual hosel weight bore to add as much as 9g more weight to the head so you could get up to D4-4.5 if the head starts at 274. As always, there is a +/-tolerance for all the specs including head weight. So we will have some heads that at random would be 271-272 and we will have some at random at 275-6. Y9ou can;t avoid the +/- tolerance.

      So if you have heads on order and you want to be sure of the weight, ask for a head weight selection on the order and we’ll do our best to pick to the weights you want.

      Feel wise, I’m very used to the feel of our high COR face irons from previous models like the 770, 771 so their thin face high COR feel is not something that stands out to be bad or less. No question it is different than hitting a thick carbon steel muscleback iron – it has to be because it is a thin face, high COR face iron with higher smash factor. but I have hit these irons a LOT in their development and whenever I would switch from high COR head to the all carbon steel cavity back, I never thought twice about it. But I recognize there are a few golfers who border on being obsessed with this forged thick face feel and for them, well, they’re just going to have to demo hit test the heads before they make any final decision.

      You have to remember that if single length were as popular and as accepted as conventional incremental length assembly, there would be multiple different head models within single length just as there are and have been multiple different head models within the realm of conventional length assembly. Look at it – all companies have super game improvement, game improvement, shallow cavity back, deep cavity back and muscleback iron styls all for conventional length assembly.

      If down the road single length were to be fairly popular, then you would see more different iron head models developed for different player types for single length assembly. in starting with one model for single length, I had to design it so that it could aim a little more at the 10 to 25 hdcp player because there are gazillions more in that category than there are who break 80. not to say that Sterling as it is cannot be used by a single digit player – sure it can. I’ve been playing it and am just fine with it. But then I personally am not obsessed with a forging thick face feel in an iron and I can adapt to the impact feel of a high COR head or cast deep carbon steel cavity back with no second thoughts.

      Again, you just have to hit test it first to see if it could be something you can play with or not.


  178. great response tom and thanks, i agree with all you say and will do just that, sounds like what i was thinking also. plus in terms of the lie, it’s the only time i’m grateful i’m not 6 ft 1! thanks again

  179. hi tom,

    love the wishon irons, owned a set of the 555m irons and loved them! delighted to hear you have produced a set of these as i know they’ll be the best cash can buy for quality!
    i’m a low handicapper but i want a change to become more consistant and also to discover the game more and i’ve become obssessed with the dechambeau swing version like moe norman from the golfing machine. i really like the idea of the simplified swing and the club setup bryson has to simply further to get an even more consistent swing than perhaps moe!! i saw one of the first questions you answered here about dechambeau and his swing and that you were talking about his unique swing and that what you were doing has nothing to do with swing or his technique more just offering single length irons. although i’m 99% sure this idea and production isn’t just a fluke coincidence with the emergence of the reigning amateur champ about to flood the majors and pro scene and become one of the most marketable talked about golfers in the world!! nice move i say! my question is tom could they be setup to work like his does i.e the XL grips and the weight they carry, and the extremely upright angle you talked about (to get that one plane swing and setup). because i read somewhere that the weights were placed in the toe area of his clubs to counter act that very aspect in terms of the upright angle. i guess what i’m saying in simplified terms is i like the way he approaches the game top to bottom and i feel it would perhaps help and suit me. not to mention it quite clearly works! thanks tom

    • JASON

      Bryson’s set is highly unusual in terms of the extremely upright lie and the much heavier heads to counter the use of the very large grips. It’s obvious he created this combination of specs as a way to force him to be able to better duplicate his upright posture and single plane swing motion. If other golfers choose to use a single plane swing, I don;t know enough about the swing technique to know if all golfers pursuing this motion would need the lie to be anywhere near as upright as Bryson. I hope not because that much of an upright lie is going to be impossible to bend to achieve with our Sterling irons. You’ll be able to get the lies to be 67*, with great care probably 68*. But not more upright than that.

      My recommendation to you would be to not jump all the way into the deep end immediately. Get one, maybe two of the irons, have us or your clubmaker bend them to +4* upright lie and build them with a larger size grip that is still reasonably comfortable but not too large for your hands. Put as much weight into the weight bore in the heads as it takes, then go out and try this with the 2 clubs for at least a month or more. if you find that you can adapt to this swing motion, fine, then you can graduate on from there to the full set. but this way if you find that this is not exactly your cup of tea for your athletic ability and swing repetition, then you would have only had a smaller expense in a couple of clubs to find out.

      Hope this helps, and thanks so much for your interest,

  180. Tom,

    I have been playing 1iron clubs for a few years now – have been sold on the single length for quite some time. I’ve been looking to upgrade my irons but haven’t found anything until today!! I’ll be setting up a fitting here soon (your club fitter finder doesn’t have anybody in the Vegas area – would you recommend that I go up into Utah or down into Arizona?).

    My go to club off of the tee right now is my 4-iron, am a little disappointed that you are starting with a 5, what was the deciding factor there?

    My preference would be to have as a consistent feel for my distance clubs as possible, i.e. I’m not looking for a 3w and two hybrids. What would you recommend for clubs between the 5-iron and my driver (I have a high swing speed and a 12 HC Here are my distances with my current set. 3I – 220 yds, 4I – 205 yds, 5I – 195 yds, 6I – 185 yds).

    I read one of your responses about the LW – have to agree there – I find that I leave the LW in my bag most of the time, I usually chili dip it from a tight light and hit it high on the face from the rough…guess I need the bounce on the SW in the tight lie and I usually just open up the club head instead of reaching for the 60 degree wedge. Did you change the bounce any for the SW or leave it the same as the other clubs?

    Looking forward to trying these out.

  181. Hi Tom,

    Good to see you back online.
    Is it possible to play a 2,3 and 4 rescue at a single length or would the distance gaps be eroded by the changes in swing speed?
    If it is possible to play the rescues at a single length would it be possible to substitute a 5 wood for the 2 rescue and then play that at the same length as the 3 and 4 rescues.
    I currently play a Driver at 43″ and a Fairway Driver at 41″. This has brought the woods under control so I am quite open to ideas that are different to the norm as long as the results are good.

    • PETER:

      Yes, thanks, it was 117 posts I missed thanks to that glitch with the system ! But I am all caught up now with answers. Hope some from early Feb were not too upset with us.

      Based on my work with the Sterling irons in research and development, I would tend to think that if one were to use single length with hybrids, the loft gaps would have to be designed to be a good bit different than normal. if I were starting such a design, my first prototypes would be a 5* loft gap between clubs. Maybe do a 17* #2, 22* #3/4, 27* #5, 32* #6 and make them all 38″. I so much prefer iron lengths for hybrids, hence why I’d do these at 38″. So if one wanted fwy woods, I would tend to look at them separately from the hybrids – maybe do 40.5 or 41″ as the length for a 15* 3w, 21* 7 wood and 25* 9 wood – or perhaps for different players a 17* 4/5w, 22* 7w and 27* 9/11w.

  182. Thanks for the swing rate response, but what are the specs ? all the ssame yes? I have a set of the 1 irons and at a head weight of 273 they came in around a D4 if I remember, so I imagine yours are close at 274 grams. Now obviously I can swing them pretty good and had a ctp the first day out but could never get a 5 iron 200 yards like my “regular” clubs. I haven’t looked through your whole site to see how much d2 to d4 would make a difference but my pro said they kinda came in heavy. I imagine some pros on the pgs tour use every swing weight from d2 to ?

    • Derek:

      Because we are a custom fitting company in everything we do, create, research and teach, we never create any clubhead design to be built with only one or with a limited number of shaft or fitting options. Our designs are offered to golfers by independent custom clubmakers which means the golfer is FIT for whatever shaft, length, lie, swingweight, grip is the best fit for him in the single length concept of the design. And the Sterling heads, just like every other one of our designs, is made with an internal weight addition capability so the clubmaker can hit the swingweights he wants for whatever shaft, length, grip he fits to the golfer. For us it is only about custom, never a standard off the rack with limited options. So the way the fitting is done is to find the shaft model best for the golfer’s swing characteristics through a test club trial basis. Then the swingweight is determined by gradually adding a little weight to the head of the test club, having the golfer hit shots and offer feedback on the head weight feel while looking at the impact position of the shots – adding more weight, getting more feedback, etc until the point is found that the golfer senses that the head weight feel when starting the downswing is not too light, not too heavy and the golfer doesn;t have to think or manipulate the club to achieve a decent repeating comfortable swing tempo.

      That’s fitting. That’s why it works better than just buying clubs off the rack already made to guess on what swingweight is right or not.


  183. Can you comment on the swing weight of the clubs?

    • DEREK:
      Sure thing, happy to make this simple because it really is. Single length iron construction is no different than any other golf club or set with regard to swingweight. There is for every golfer a specific head weight FEEL which allows them to be as consistent as they can be with regard to swing tempo, swing motion repeatability, which leads to better shot consistency. If the headweight feel is too light for the golfer’s individual sense of feel, timing, rhythm, etc, then the golfer struggles to slow down and maintain a consistent tempo and they are always fighting the tendency to be “too quick”. On the other hand if the head weight feel is too heavy for the golfer, the golfer will struggle with making more of an effort to swing the clubs, which results in him making swing errors from fatigue or from just plain moving around too much during the swing as they try to muster the greater effort to swing the heavy feeling clubs.

      Single length for us is no different than finding what headweight feel (and shaft) in their 7 or 8 iron has always felt the best, has always allowed them to feel more consistent with their tempo. Then duplicating that in the single length irons for EVERY iron. Hope this helps.

  184. I am keenly waiting to try out the single length clubs. Are they out yet?

    • Thanks for your interest. The first orders from the clubmakers for the Sterling single length heads will begin to ship next week. But it is going to take us until late May to get caught up with all the orders from clubmakers for the heads because the initial demand was overwhelming – and in saying that, we still have no idea what the on going demand curve is going to be for the single length irons between now and late May. Production lead time is 75-90 days so even when we jumped on ordering more in early Feb, we knew it was not going to be until May that we got caught up with demand. Best thing we can recommend is to contact the clubmaker in your area, ask him if he has Sterling heads on order for use as demos or test clubs, and determine your timing based on what he tells you. Thanks much for your interest though, and we’ll get caught up on this as soon as we can.

  185. Dear Tom,
    I would just like to make one comment. I have always be interested in the one length iron set. However,realizing how complicated it is, would it not be easier to do it on a 2 or 3 tier premise. 3-4-5 one length 6-7-8 one length 9-PW-AW another length. Perhaps separated by a 1/2 inch or so. Might this be easier to have Golfers acclimate to this, and be easier to adjust the distances?

    At this time (having been in Golf retail as well as fittings) I think this would be a easier way to enter main line golf club market. A starting point till technology makes it easier to achieve the distances needed at a reasonable production cost for complete one length irons.

    Thank you,
    Olino Portanova

    • Olino:

      Single length is not a complicated matter in the irons. Yes, for sure, it does require that the iron heads be specially designed to all be the same weight and same lie angle and lofts properly designed to match with the single length. But with such a set of specially designed iron heads, the fitting of a single length set is really quite simple for the golfer to be able to end up with the set being able to perform well for him or her. While any golfer can do anything they want with the length of their irons, the whole reason that single length even exists is to allow every iron to have the same exact swing feel. When the irons are all the same length, same shaft weight, same total weight, same swing weight, same balance point, same MOI, then each iron has PERFECTLY THE SAME SWING FEEL. You can’t do that when you have different lengths in a set, no matter how hard you try. So to offer a set in a series of 2 or 3 or 4 different lengths, that destroys the whole reason that single length is even a concept in iron set design for a golfer to try to achieve better shot consistency and more success with the low loft irons.

  186. Availability? When…. I’m ready!


      Slowly but surely, I have to say. The pre arrival demand in orders from clubmakers were way beyond what we could have estimated so we are in “catch up mode” trying to increase production of the heads to meet the initial demand. Orders already placed with us by the clubmakers for sets and for demos will just begin to start shipping next week. From then on it will be a steady flow as we slowly but surely keep working on catching up. Right now it looks like we may be all caught up by late May. So if you are interested, talk to your local clubmaker, see if he has demos or sets on order with us, and take it from there. There will be another outlet for the irons at that will launch pretty soon and this company does have quite a number of sets on pre order with us that they will be able to offer to golfers.

  187. Will my short irons now be as inconsistent as an 8 iron?

    • CHRIS
      All irons in the single length set will swing with precisely the same swing feel that will be based on either a 7 or 8 iron length, whichever the golfer and the clubmaker deem better or more comfortable for the player. That’s the benefit – when the clubs are the same length, they then will have the same shaft weight, same total weight, same swingweight, same head feel, same balance point, same MOI – same EVERYTHING that has anything to do with swing feel when you swing a club. Being 7 or 8 iron length, that offers the additional help of more on center hit consistency because after all, do you hit an 8 iron more on center more of the time than a 5 or 6 iron (which is what other single length sets are made to be). So that’s the potential of the concept. But it still has to be fit right to the golfer in terms of the shaft weight, flex, swingweight, lie, grip size that best matches the golfer’s swing characteristics.

  188. When can we order!

    • Are post being received?

    • Sorry but I just found out today that the auto notification for posts was somehow turned off. So I am just now beginning to catch up with these. Sorry about that.

    • If you are inquiring about ordering the full assembled single length set of irons, go to and give them your email address. as soon as they are ready to launch, which should be early in April, they will contact you and you can order a set at that time to your required specifications.

      Thanks for your interest,

    • Charlie
      The clubmakers who custom build our designs for golfers did begin to place pre orders for the Sterling single length iron heads starting in late January, in advance of the late March beginning arrivals of the heads from our production factory. In order of how the orders were placed, next week we start shipping these orders to the clubmakers. The demand has been furious and caught us a little more than off guard so we have been working since very early Feb to increase production to catch up. But production has a 75-90 day lead time so catching up means that it’s going to take until mid May to get all present orders for the heads shipped to all the clubmakers who have them on order. To get the Sterling single length clubs as soon as possible, I would recommend that you go to and register – when this site is up and running very soon, you will be contacted and you can then place your order through that website. Thanks very much for your interest,


  189. I am very interested in this iron concept. Right now I’m not in a position for buying new clubs, but when I am, I could see these as well as driver, woods, hybrids and wedges from you working well for me.

    • Thanks Mark for your interest ! We’re here when the time comes. And if you need help with us finding a good clubfitter with whom you can work, holler at us with the name of your town/city and we’ll let you know who might be the best to work with in your area.

  190. Hey Tom,

    Just wanted to know when exactly are these coming out? any specific date? And do you take pre orders? Any price range for these?

    • Ahmed
      All of our designs are available only in custom fit form, only from independent custom clubmakers. We do not offer any of our designs through the usual big box golf stores or pro shops because that business is all “standard off the rack, one size fits all.” And we are TOTALLY committed to the benefits of custom clubfitting. To get any of our designs, you would use the FIND A CLUBFITTER search tool on the home page of to see if there is a certified clubfitter in your area with whom you could work to be custom fit. The clubmakers are all independent businessmen so they set their pricing for their services and for the custom fit clubs they build from our designs.

      Pre orders to the clubmakers began in late January. Shipments begin next week. But the demand has exceeded the initial production supply so we are working very hard to increase production as fast as possible to catch up with all the orders from the clubmakers for the heads. Two things I can suggest – 1) use the Find a Clubfitter search tool on our website to find a clubfitter in your area – if there is one, call him and ask about his status with ordering the Sterling single length heads for his inventory and clubmaking use – and as for his pricing too. 2) or, you can go to and register with this site to be contacted when this company is up and running with providing golfers with the custom fit custom built Sterling sets. This site will be up and running in April to offer golfers an alternative way to obtain the Sterling single length design.

      Thanks for your interest,

  191. Hi Tom– I have two questions. I’ve had great results with Aerotech Steelfiber shafts. Could a single length set be built with these?

    Second, I’ve always loved this concept (I thought about it even before DeChambeau had his set built), and I wonder if it would be possible to extend it – with some modifications – to include the entire bag except for the driver. What would it take to design a three length bag, as follows:
    1. Standard driver.
    2. 7-SW at 8 iron length.
    3. Remaining 5 clubs (3W, 3,4 H, 5I, 6I) at one length, maybe 5 or 6 Iron length?

    Thanks. JP Bouffard

    • JP:

      ANY IRON SHAFT can be used with any single length set as long as the shaft fits you and your swing characteristics. There is no such thing as a special shaft for single length performance.

      I’d be careful about the concept of making the 3w, 3h, 4h, 5i and 6i all at a 5 or 6 iron length. More than likely you would lose distance with the 3w, 3h and possibly the 4h compared to what you have been used to with these clubs at their conventional length. part of that depends on what length you have played for your 3h and 4h. If you bought OEM company hybrids, then their lengths for the 3 and 4 hybrid will be much longer than a 3 or 4 iron. At a 5 iron length of 38″, that’s 5″ shorter than a normal 3w length. That would cause a significant loss in clubhead speed which could not be made up in anyway with a high COR face design or loft.

      If your 3 hybrid and 4 hybrid were OEM length, which puts them around 40″ to 41″, going with a 38″ length could drop the clubhead speed enough that you might not get your normal distance with these hybrids you used to. But if your current hybrids are low COR face models, meaning if they are conventional cast stainless steel, then perhaps if you went with a high COR face design in the 3 and 4 hybrid head, at 38″ you might be ok for the distance for these clubs. And then with the 5 and 6 iron, you’d probably have to tweak the lofts so that you would not end up with a longer distance gap between the 7 iron at 8 iron length and the 6 iron at 5 or 6 iron length.

      Hope this helps,

  192. Tom , How about the 24/38 rule? Does this concept do away with that rule?
    Just asking.


    • LOUIS
      Actually it proves the 24/38 rule. Golfers can hit the 23* loft #5 iron in the Sterling single length set because its length would be either 37″ or 36.5″ – not 38″ or more. The substantially shorter length does make it easier for golfers to hit the 23* #5 iron more on center than they ever could if that club were a 38″ length. Now it is true that if the golfer has a slower iron speed, such as below 70mph for a normal 5 iron speed measurement, they should not use the Sterling 5 iron and possibly not the Sterling 6 iron because those slower speeds can’t generate the ball speed and spin required to really get these irons well up high in the air to fly.

      But that’s also true for any golfer with a sub 70mph iron speed trying to hit a normal 3, 4 or 5 iron in a conventional length set too. hence the reason when you have a golfer with a sub 70mph iron speed, their set makeup should not include a 3, 4, 5 and sometimes even a 6 iron – and the clubs he needs to have for distances above that should be high loft fwy woods or hybrids made to conventional lengths.


  193. I feel comfortable from PW to 8i.
    My efficiency (way to calculate it: I measure my ball speed on each club) drops from 7i to 5i…

    Would it be a good idea to only change the 7, 6 and 5 iron with the same length shaft ?

    • BW
      No. Please understand that one of the two chief benefits for a single length set is to have the swing feel of every iron be identical so that the golfer can gradually develop a higher level of swing repeatibility and swing consistency, and from that better shot consistency. When you make all the irons have the same length, then they all have the same shaft weight, same shaft flex, same total weight, same swingweight, same balance point, and the same overall MOI for every iron. That is every single possible thing in a golf club that has an effect on the swing feel of the clubs – identical. When you make clubs to different lengths, no matter what you destroy this chance to duplicate the same exact swing feel for every club.

      I am sure if you experiment enough and tweak the weighting and lofts enough, you can most certainly do what you describe and be fine for performance.

      In the Sterling design the way that I am working to overcome the loss of ball speed from the low number irons being shorter in the single length set than they are in a conventional set is with my high COR thin face design plus a little lower loft. Those two design elements allow the #5, 6, 7 irons in the Sterling set to hit the ball as far if not farther than what the golfer is used to hitting his 5, 6, 7 in his conventional length set. but to then also have the two benefits of 1) more on center hit consistency with the 5, 6, 7 because they are now shorter than they were in the conventional set; 2) more shot consistency for all the clubs because they all have the same exact swing feel from all being the same length and same everything else.


  194. Hi Tom,
    I am very interested in these irons. Can you give us a idea about what price will be?

    • Thank you Joe and my apology for the delay in responding. The notification feature on comments to our blog was broken or off and no one here was aware of any post comments coming in over the past couple of months !! Oops on that !! But better late than never I hope!

      Please take a moment and head to and register your email there. We’ll notify you when the site goes live and the sets are ready to offer. Should be in early April based on where we are at with the work on this site.

      Thanks again and sorry for the delay,

  195. Tom, I know you require custom fitting for these irons and I realize how important that is when buying clubs. My problem is that I live overseas not near any of your custom club fitters. I do know most of my specs when it comes to clubs and am wondering if there is a list of specific measurements I could send you to have the clubs custom fit for me or as close as possible. Any information you could provide on this would be greatly appreciated. Thanks for your time and consideration.

    • Michael

      I am so sorry for the long delay in responding. The notification feature to tell us when posts and comments were made on this part of our website was not working for several months and no one knew that until an IT check this week discovered the glitch. Very sorry about that.

      Yes, if you are still interested, we’re setting up a website for this very thing – – you can go and register now so that when it goes live pretty soon you can get notified. There you would be able to order and input specs.

      Thanks for your interest, and again, very sorry for the delay,

  196. Hello, can you recommend a club fitter in the Richmond,VA area. Interested in your Sterling SL irons coming out in March.


    J Warriner

    • JOHN
      First off, my sincere apology for the delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that. The very best clubfitter closest to Richmond is Charlie Sampson or his own company, Charlie Sampson Golf. Charlie operates two fitting studios – one in Florida he mans from Oct through April and then his main shop in Glen Ellen, VA where he is from May to September. I know you said you are interested in the Sterling single length irons in March as they begin to come out next week. But early pre book orders from the clubmakers that began in late January when we first announced the model coming have eaten up all the heads on all the production shipments through early May. So if you met with Charlie today were he in Va now, it would be mid to later May before he could get the heads for your set.

      Here’s what I recommend. Email Charlie now at or contact him now through his website at to tell him your interested in being fit for the Sterling irons and to try them out. Ask him when he actually is to return to Va. I know that Charlie does have orders in now for test irons and demo irons as well as a couple of sets of the Sterling irons. So I am sure he’ll have the test clubs for you to hit if you meet with him in May when he returns. And more than likely our supply by later May should be pretty good – but of course you could ask him to order a set to get on the list here so we know they’d be shipped in mid to third week of May.

      The next closest clubmaker is 50 miles away and even if you met with him tomorrow, he could not have heads for a set for you to custom build until the same time Charlie could. And Charlie is not only closer, but I have known him personally for decades in this business so I can verify that he is really good and very experienced in his fitting skills.

      Hope this helps, thanks again for your interest and again VERY SORRY for the delay,

  197. It seems as though I could strengthen the 5 iron 4 degrees and weaken the sand wedge four degrees to add a couple more clubs to the makeup and get a more “full” set. Can you confirm that this idea is a possibility?

    • ANDRE:
      First off, my sincere apology for the delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      I would not recommend bending lofts by 4 degs on any iron, whether that be one of the Sterlings or any other iron. That much of a loft bend will drastically change both the sole angle and the amount of offset in the head – not to mention put an odd looking curve in the base area of the hosel and probably leave some distinctive wrinkles in the metal where that much of a bend is done. if we do the bends, we certainly can keep the wrinkles to a minimum but we cannot over come what will happen to the sole angle and the offset.

      Plus, unless you have an iron clubhead speed of nearly 90mph or higher, you would not be able to get a -4* loft 5 iron airborne enough for it to perform well. At a single length of 36.5 to 37″, clubhead speed is lower by around 4-5mph than what it would be with a 38.5″ length for a normal 4 iron. That means less ball speed, lower spin, less shot height for that low of a loft. And it would take a 90mph + speed with that iron to get the ball up enough to make it possible for a 19* loft head to perform well at a length of 36.5 to 37″.

      I’m betting anyway that if you hit this sterling 5 iron, if you have a clubhead speed with your present 5 iron of 80-85mph, you will hit this Sterling 5 iron about the same distance as the 4 iron in your current set becausee of its high COR and 23* loft – even at 36.5 to 37″ in single length.


  198. As an addition to my question; if a 3, 4 or lob is not available would you have a recommendation on your experience as to what would be best in filling the place of those clubs. Thank you again.

    • ANDRE
      First off, my sincere apology for the delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      You can’t think of the Sterling single length set in the same thought pattern of same iron head numbers. The combination of the high COR face + lofts + the 36.5 or 37″ single length for the #5, 6, 7 irons in this set will generate plenty of distance for normal clubhead speeds. Most golfers are going to probably hit this Sterling #5 iron as far as their current normal length 4 iron. And then distance gaps will be very generous from club to club ending up with the golfer hitting the gap wedge the same distance they hit their current gap wedge in their normal length set.

      So what you do with the rest of the set is you find out from hitting the Sterling 5 iron, just how far you hit that club when you hit it well. You note that yardage and you add 15 yards to that. Then you look among your hybrids to fairway woods for the clubs that achieve that distance. Once that is found, you add 15 yards again and do the same thing over again to find the hybrid or wood to follow that.

      For example, when I play with the Sterling single length set at my preferred length of 36.75″, I play the 5 iron through gap wedge. I hit this Sterling 5 iron to a carry distance of 188-190 yds. My next club above the Sterling 5 iron is a 21* #3 hybrid of 39″ in length which I hit a carry distance of 205-208 yds. Next above that is my 5 wood at 41 1/2″ and 18* loft which I hit 220 carry. And next above that is my driver because I just do not like trying to hit a 14-15* 3 wood off the deck.

      So that’s how you go about it with the other clubs. Find how long you hit the Sterling #5, add 15 yds, find that club. Add 15 more yds to that one, and go find that club.

      Hope this helps,

    • When will these be available and how much will they be?

    • BEN
      Thanks very much for your interest. Two ways you can pursue a set of the Sterling single length irons. One, to go to the FIND A CLUBFITTER search tool found in the middle of our home page at Put in your town/city of residence and see if a certified custom clubmaker is in reasonable proximity to where you live If so, you can call the clubmaker to ask if he will be offering the single length irons and when he feels he would have demos and inventory in his shop. All of the clubmakers are independent business people so they set their own retail pricing for everything they offer in their work. This you would as the clubmaker to quote you for the cost of the fitting and the clubs. While we can offer suggested retail pricing, by law we cannot control the retail pricing of the clubs that a clubmaker would custom fit an build for a golfer.

      Two, we will also be supporting a direct fitting and sales offering of the Sterling irons to golfers through The site will be going live very soon, but you can go there now to register to be notified when the site is active and the clubs would be available.

      Thanks very much,

  199. Tom, I am going to get a set of the sterling irons. The one thing I have my concerns about is the wedge set up. I really got used to the Cleveland 52 56 and 60. would you suggest getting 5-pw sterling then getting wedges I like shafted and weighted the same? What is the bounce and grind on the gap and sand wedge in the sterling set? any chance to get micro groves in them?

    • Kevin
      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      If the player has definite preferences for his gap, sand, lob wedges, then yes, it is totally ok to depart from the single length set to go with the wedges that are more comfortable and bring more confidence. The reason is because so many players like you tend to hit these three wedges at less than a full swing, hitting half, three quarter, knock down, etc types of shots. Single length’s forte of offering identical swing feel is something that can work fine for less than full swing shots for sure, but it shines more for the full swings on irons when everything is regularly moving at full speed for each club to be hit its normal max distance on an approach shot.

      I am a little example of this – when I played the single lengths all during the final development time, I found I wanted to go back to my normal 35.5″ sand wedge with its D5 swingweight. The single lengths as I fit them to myself for final testing were 36.75 and D1. And I was fine. because the real areas single length has potential are, 1) being able to hit the low loft irons more on center more of the time for more consistency that way; 2) having identical swing feel for all the irons so full swing shots can be more consistent, with better swing repeatability.

      Hope this helps,

  200. How do your clubs compare to 1iron single length clubs.

    • bill:
      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      Differences between our Sterling single length and 1-Iron Golf (and Pinhawk, the other older single length product)
      * They’re based on a 5 or 6 iron length as their single length. We’re using a 7 or 8 iron length. Shorter length makes it easier to hit more shots on center.

      * shorter single length makes it so there is much less chance of hitting the high loft irons too far. With a 6 iron length, your 8, 9, PW, gap wedge are between 1″ and 2″ longer than they are in the golfer’s conventional length set. This makes it more possible to hit these scoring clubs too far, farther than the golfer is used to. 8 iron length is then 0″ to 1″ longer than the #8 to gap wedge so controlling the distance of the high loft clubs is easier to do.

      * Our 7 or 8 iron length makes it easier to hit the low loft irons on center, solid and from that, their max distance. 5 or 6 iron length is still long enough that a lot of golfers will still not be good enough to hit the low loft irons as much on center as they could if the single length were a 7 or 8 iron length.

      * a shorter 7 or 8 iron length could cause more distance loss with the low loft irons. But we offset that with our long time experience in having invented high COR irons with our thin face, high strength steel face engineering ability. So with our high COR faces in the #5, 6, 7 iron in the Sterling set, we give back ball speed that is otherwise lost when using a conventional low COR face iron, such as the head models are for 1-Iron and Pinhawk.

      * we offer an alternative #5 hybrid to sub for the 5 iron if the golfer has loved hybrids in his present set. The 5 hybrid is the same single length as all the other single length Sterling irons.

      Thanks for your interest,

  201. Very interested in trying the Sterlings. Any fitter you would recommend in the DC area?

      Thanks very much for your interest and I hope this helps,

  202. Hi Tom,
    Can’t wait to try the Sterling irons this May, but I do have one question. I normally play a half set of irons. I intend to order and be fitted for a 5i, 7i, 9i & GW. What would the approximate difference be between clubs e.g. 10 yards, 15 yards, etc.
    Thanks for your time.

    • TJ

      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      The distance gap between irons in ANY SET depends on three things – 1) your clubhead speed first and foremost. The higher the clubhead speed, the greater the distance gap for the same loft difference in degrees between irons. So a golfer with a 70mph iron speed playing irons with 4* loft gaps would see a distance gap of 9-10 yds between irons. But a golfer with an 80mph iron speed playing irons with a 4* loft gap would see 14-15 yds between irons.

      2) what the loft gaps really are and how that coordinates with the face design and Center of Gravity of the heads. Some companies make sets where the loft gaps can be 3*, 4* or 5* between irons. This most certainly has a bearing on what you see for distance between irons.

      3) the +/- tolerance for loft angle on each head as a part of the normal production process of the heads. EVERY clubhead production factory has a +/- tolerance for errors in manufacturing the heads they make for the various companies. The BEST factories have a +/-1* tolerance for loft and lie on the irons they make for the golf companies. Typically that means in a run of 100 of the same iron head, 65% will be dead on the loft spec, 20% will be +/- 1/2* and 10% will be +/-1* from the design spec. It cannot be any better than that because of the many steps in production and the intricacy of making a ton of heads in mass production. so it is possible in a set designed with 4* loft gaps to possibly have a 2* spacing, 3*, 4*, 5* or even 6* spacing between irons, randomly dependent on how this +/- tolerance falls for the heads in a set. Thus if you see two clubs in your set which are only 5-6yds apart but then you have two clubs which might be 15+ yds separated, what you are probably seeing is this +/- tolerance messing things up.

      But things like this can be corrected by a good clubmaker with a loft lie bending machine. Lofts in the Sterling single length set in order from the #5 to the 9, PW, GW and SW are 23, 27, 31, 35, 40, 45, 50, 55. We designed the heads from soft carbon steel so if any loft (or lie fitting) bending is needed to tweak the distance gaps to be perfect between irons, it is VERY EASY to do for the clubmaker who fits and builds the set for the golfer.

  203. Love love love this concept. I hope this is extremely successful, and this gets extended to a full bag. Maybe one length for hybrids, one for irons, and one for wedges.

    Wondering what would be the intended/designed gap between clubs, say for an 80-85 MPH standard 8 iron swing speed?

    • CL
      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      We hope they are successful too! But on the other hand, since we have always been a custom engineering company in custom clubfitting, we do have 5 other iron design options all in conventional incremental length design for the players who just can’t wrap their heads around the single length concept.

      There is no question that a set of clubs can be customized to any number of different length and length progression options. And if the golfer is patient and committed to take the time to keep testing and trying in terms of weighting the clubs, it is possible to fit a golfer accurately for good performance with any number of non traditional length formulas.

      Do keep in mind though that one of the two main benefits from a science standpoint for single length assembly is the fact that when you make all the irons in the set the same length, you perfectly duplicate every possible element that has an effect on swing feel of the clubs to each other. Same length, same shaft weight, same shaft flex, same total weight, same head weight feel, same swingweight, same balance point, same MOI of the clubs means that everything that controls swing feel is PERFECTLY THE SAME.

      When you start to change lengths, you break this and there is no possible way you then can make EVERY element of swing feel perfectly the same for each iron. Why that is important is because identical swing feel opens the door to better swing repeatability, more swing consistency, and more shot consistency from iron to iron. While a ton of trial and experimentation work with all sorts of other length formulas can make a very playable good performing set, you cannot perfectly duplicate swing feel when you break into different lengths.

      With the Sterling iron lofts, for an 80-85 mph 8 iron speed, you should be looking at 15-16 yds gap between the irons. That’s a pretty high 8 iron speed so hence the gaps are a little more. But this too could be a little different depending on your angle of attack with that 80-85mph speed – more downward A of A might make the gaps a little less.

  204. Tom,

    I’m one month away from being custom fit for a set of the new Sterling single-length irons. This year more than any other, I’m really excited to get out to the range and golf courses.

    I read in one of your replies your thoughts about the ever-so-tricky 60-degree lob wedge and I agree with you. I’ve gone under the ball a few times when hitting in high rough. Not the easiest of clubs to master. When I purchase the 5-SW, I’ll have 8 new clubs in my bag. Add my putter and driver and that’s 10. The good news is, I’ve got room for 4 more.

    I’ve checked your website and looked at your fairway woods and hybrids but am not sure which ones to choose. The loft of the SL 5-iron is 23-degrees. Should the 4 (wood or hybrid) be another 4 degrees less or is this the point where 3-degree intervals begin? The goal, of course, would be to get the same distance gap between the SL 5-iron and the next higher club as the distance gap between the 5 and 6 iron.

    Which 4 clubs would you recommend I add?

    Thanks for all your hard work.

      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      Best thing I can tell you about clubs above the #5 single length iron is to hit the 5 iron and note very closely what your distance is with the club for a solid, on center hit.

      Add 15 yds to that number and think on your experience with your hybrids and fairway woods to figure out what loft at about what length could get you that +15 yds over the distance of the Sterling #5 iron. Once you know that, add 15 yds to that club and do the same thing all over again as you work your way toward the driver. Differences among golfers in clubhead speed and angle of attack, as well as golfer ability, will make what these other clubs are to be different for different golfers.

      For example, last year when I spent a good amount of time playing the Sterling irons as a final part of my own testing work, I was playing the #5 to gap wedge at 36.75″. I have a 78-80mph # 8 iron clubhead speed with -2.5 to -3* downward A of A at that length. My club above the 5 single length was a 39.5″ / 21* hybrid. Next above that was a 41″ 17* loft #4 wood. And then the driver. I could have put a 3w in there, but I’m much more consistent in hitting the ball high to fly for long 2nd shots with that 41″ 17* #4 wood than any 3 wood. So I skip the 3w and only have it if I happen to play a course with a ton of very tight par 4 holes where I might not be as straight with my 44″ driver as I could be off a tee with a 42″ 15* #3 wood.

      Hope this helps,

  205. Hi Tom

    about 3 years ago I had a set of the 1iron single length irons and liked them however you couldn’t really work them enough. I am a left handed golf 6hcp and was thinking about going back to a set of the single length irons. will yours have a LH set availability?

      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      We have to do some watching and waiting to see if the left hand version can be a possibility. First is to see if this model “sticks” when it ships and goes into golfer’s bags. Single length is a very different, very non traditional and to some, very controversial concept for an iron set. Some golfers are going to be pre disposed against it from day one. So we have to see if it has sticking power through the spring and summer as it gets out into more bags.

      Second we then have to look at the quantity of RH heads sold. Never in 31 yrs of clubhead design have I ever seen a left hand model sell more than 8% of the units it will in RH. But tooling dies and inventory costs the same for RH as for LH. So as a small company, I am sorry to say we have to look at the numbers to see if the LH version could make sense to add on. We’ll hope so.


  206. I saw that Jacob had 1 iron golf single length clubs on his what’s in the bag section of his profile I thought David lake has been making single length for a long time

      1-Iron Golf has been around for some time. I first remember a company named Iso Vibe Canada selling single length iron sets in 1986, way before David Lake made his version. So the concept is not new by any means. jaacob got interested because of an experience with 1-Iron golf. And he did push the sets on his web site because he was very convinced of the viability of the model. But he experienced things with his 1 iron golf set that he did not like and that’s what prompted him to show up on my doorstep in the fall of 2013 to see if I was interested in trying to figure out a way to design a better single length set than what was out there. 2 1/2 yrs later here comes the Sterling single length set – very different in many ways from 1-Iron Golf and I think pretty decent if I do say so myself.

      I do thank Jaacob for putting the bug in me to do this. I hadn’t really thought about doing something like this before he started to push me into it. And while it took a while to do it, I had a good time and I did most certainly learn a lot more about iron performance in the process.


    • Hey Bruce!

      Yes, at the time of your comment, I still had the 1Irons in my bag. My personal set of Sterling Irons arrived in late February. My WITB pages have since been updated. 🙂


  207. Swing weight? d2? I think the 1-irons brand came in very heavy.

      We are so completely unlike 1 Iron Golf. They simply make a single length model of irons and only offer them with a very limited number of build options for the golfer. We’re a custom engineering design and research company engaged in the engineering of many different custom clubhead and shaft designs plus serious research done in clubfitting technology to write and teach people in the industry the technology of professional custom fitting. We offer 5 different driver models, three different fwy wood models, 6 different iron designs other than the Sterling single length with 8 different shaft models – all of our own engineering and design work.

      Sterling irons have to be custom fit for each golfer by a custom clubmaker who will analyze the golfer’s swing characteristics and determine what single length, what shaft weight, what flex, what bend profile, what total weight, what swingweight, what lie angle, and what grip model/size. so there is no such thing as a “standard” set of Sterling single length irons with any type of “standard swingweight.” If the golfer needed a 55g shaft with a C5 swingweight, he can get that just as a golfer who needs a 120g shaft with a D5 swingweight can get that.

      It is and always will be about professional custom fitting for us here at Wishon Golf.


    • I have not tried out a single length system. But, assembling a few sets of clubs and paying particular attention to swing weights – do you believe a D-2 swing weight is heavy ?

    • TONY

      The relative FEEL of swingweight is also related to the length and the shaft weight of the club. Not to mention each individual golfer’s perception of what they feel is heavy and what they feel is light. So D2 with a 120g steel shaft is going to have a different head weight feel perception to a golfer than will D2 with a 55 gram shaft. There is no question that the importance of fitting swingweight lies in finding what head weight feel will best match to each golfer’s swing tempo and timing so they are not having to consciously do anything in their swing because of the club either feeling too head heavy or too head light to them.

      Hence we fit EVERYTHING in the club except swingweight first – length, lie, shaft flex, shaft weight, grip size – and then with a test club you start to let the golfer hit shots as you gradually add weight to the head with lead tape. You ask the golfer for feedback on what he senses with regard to the head weight feel. You try to get the test club work to the point the golfer starts to say the head weight feel is too heavy, then you back off some of the weight and go with that.


  208. Does the fitting process involve hitting all the clubs to verify distance gapping?

    • Steve:
      First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that.

      All the clubmakers who fit and work with any of our many different clubhead and shaft designs are INDEPENDENT custom clubmakers. They are not formally tied to us in anyway and they run their businesses and do their work as they see fit based on their own experience and study and training. yes, for sure, we provide the clubmakers with the most and best technical information to teach them and build their knowledge. But as the old saying goes, you can lead a horse to water but you can’t make him drink.

      We have told the clubmakers in our training videos for the Sterling single length sets that they should lead the golfer through a test hitting period with the Sterling irons so the golfer can assess shot distances with the test clubs. And we have told them to observe distance gaps and when necessary to tweak the lofts to accommodate that. That’s a huge reason I designed the bodies of the Sterling iron heads from 1020 carbon steel so they will be VERY easy to bend for loft tweaks and for lie fitting too.

      But you cannot be sure every clubmaker is going to do loft tweaking on the sets because they are independent business people and I can’t force them to do anything in their work if they do not want to or do not know to. So you would be advised to bring this up with whoever you are contemplating working with in the fitting and building of your set.

      Thanks much

    are there any issues with hi cor irons for use in pro tournaments?

    Keep up the great work

      They are in the process of going through the USGA conformity inspection now. We hope that will be done pretty soon. But as of today, nope, they are not on the USGA list, but it should not too much longer.

  210. Hey Tom,

    What shaft options going to be offer with these set?


  211. Hi Tom
    I live in England about 10 miles from the Scottish border, I am a 3 handicapper 58 years young and still trying to improve!! The idea of of single length irons makes a lot of sense to me, we’re in the UK could I try your new Sterling irons, also is it possible to go from 4 iron to PW, as my other wedges work fine?

    Kind Regards

      First of all, please accept my apology for the long delay in responding to your question and post, The auto notification feature of the blog that is supposed to tell me/us that posts are waiting for response was “broken” or messed up such that none of us knew that posts were here and waiting. VERY sorry for the Oops on that.

      I would suggest that you contact our stocking distributor in the UK to ask them if they can recommend a custom clubmaker in your area with whom you can work to test hit the Sterling single length irons when they are available in the UK. We’re probably looking at sometime in the summer for that because we do have some logistical matters to work out on the single length irons to get them into the UK for distribution. Diamond Golf sells clubmaking supplies to all the clubmakers in the UK so if you contact them, they could tell you if there is someone in your area who can work with you. Diamond Golf is at 01903 726 999 or

      Thanks very much and again, so sorry for the delay in responding,

  212. how are the shafts prepared for the sterling iron set. are they tip trimmed all the same or are the tip trimmed just like a conventional set of irons? i have been a fan of your club designs for a long time. thanks Kevin

VERY sorry for the Oops on that.

      The sterling irons are designed so they could be built to either a 7 iron or 8 iron length for all the irons in the set, as per the fitter’s decision or the golfer’s preference based on comfort over the ball. Once that decision on the length is made, then all you have to do is think that you are building a set of all 7 irons, or of all 8 irons. So the shafts all get tip trimmed exactly the same amount, based on which of the two lengths you choose. And then all get butt trimmed to the same chosen length. Easy.

  213. Hi Tom,

    I think you have kicked a wasp’s nest with this one.

    The major oem’s are going to be really upset if you get the single length concept off the ground unable as they are to produce a usable set in this category. They must also be hoping against hope that Bryson DeChambeau disappears without a trace.

    Is it possible to play a 2,3 and 4 rescue at a single length or would the distance gaps be eroded by the changes in swing speed?

    If it is possible to play the rescues at a single length would it be possible to substitute a 5 wood for the 2 rescue and then play that at the same length as the 3 and 4 rescues.

    I currently play a Driver at 43″ and a Fairway Driver at 41″. This has brought the woods under control so I am quite open to ideas that are different to the norm as long as the results are good.

      don’t worry about the major OEMs being upset with anything we do. seriously, we are but a fly on the windshield to them. But what will be interesting to watch is how this whole matter with deChambeau is going to play out as he finishes his amateur invites to the majors and turns pro after the Open in July. No question with his awareness level being high among golfers, he will command a much more $$ endorsement contract than the average college kid who turns pro. I’m betting the bidding will easily have to hit $2 million for him.

      There is no question whoever signs him is going to have to custom make a single length set for him to play. That part will be easy – reverse engineering any existing model is no problem whatsoever. But then the fun will really start in terms of watching what happens. Will the OEM begin to market a single length set? They’d have to you would think. How could you have your new golden boy playing a single length set with your name on it and you don’t put it on the market? So when they do, how do they market it, how do they position it in comparison to all their other multiple conventional iron sets? How much do they market it compared to the other iron sets? How do they explain to a golfer which type of set to use – single length or incremental length?

      Lots of things for them to have to figure out. But I don’t think they will shy away from it because right now these big companies are getting desperate for something new to market to the golfers. It’s just a matter of do they dip the toe in the water first or do they jump in the deep end?


  214. Hi Tom,
    Heads look really nice. Very interesting concept
    Do you have any data of ballspeed, launch angle and apex available?
    Just to get an idea of the flight trajectory per club.

    • Baudi
      First of all, please accept my apology for the long delay in responding to your question and post, The auto notification feature of the blog that is supposed to tell me/us that posts are waiting for response was “broken” or messed up such that none of us knew that posts were here and waiting. VERY sorry for the Oops on that.

      While we have data from our hit testing during development, it really would not be of valid use for you to assess whether you could play the design. The reason is because your angle of attack and your clubhead speed could be different than the hit testing conditions we used during development tests. Speed and A of A have more of an effect on shot height and launch angle than do the design characteristics of the club heads themselves. In the end, the very best way for any golfer to assess the performance of any club design is for the golfer to test hit the club so they can see for themselves. I can tell you from the golfer focus group hit testing that for all golfers, the height and shot shape of the #7 to wedges was felt to be completely normal and similar to every other iron the golfers had played. but for the 5 and 6 irons, this was a case where the higher the clubhead speed of the player, the higher the trajectory and shot pattern of these clubs. For the players with more average clubhead speed such as 75mph for a 38″ 5 iron speed or lower, this is where the shot height of these lower loft irons was lower than the rest of the Sterling heads. not lower than these golfers were used to hitting their own normal length 5 and 6 irons. Which simply is another way of saying that for EVERY golfer, as clubhead speed drops, they should not be using lower loft irons and should be using hybrids or high loft fwy woods.


    • Hi Tom,

      Thanks for your extensive reply!
      Your answer pretty much filled the gap.
      I am really looking forward what it It will be like to hit these heads for real.

  215. Hi Tom. I don’t know if this has already been asked but is there a possibility of thes coming in a more blade like iron. I am old school and although I understand cavity backs, I prefer the look, trajectory and feel(the sting too) of blades. Height is not a problem for me either.

    Thans for all your contributions to the industry.

      There is no question if single length as an assembly concept were to catch on and acquire more followers, it then would be possible to create other head models to be used in single length fitting for golfers. Single length is an assembly concept. It is NOT a club model. Just like incremental length is an assembly concept and not a specific model. As you know, with incrremental length irons, companies do create several different versions of the models – super game improvement, game improvement, traditional cavity back and traditional muscleback are all examples of types of iron head models that have been made to be built to incremental length assembly.

      Single length should be the same way – different head models for different golfer types. But that can’t happen unless single length as an assembly and fitting concept catches on enough to where there is enough demand to create and offer different model types for single length assembly. So the answer to your question is “we’ll just have to see if single length begins to acquire enough followers.”

      Thanks much !!

  216. Hi Tom,

    I’ve been very excited to try this set out. Anyhow, just wonder if this set is coming with lefty too?

VERY sorry for the Oops on that.

      The question of left hand in the Sterling single length model depends on two things – 1) if the single length design maintains demand to prove it can be popular enough to stay around. 2) if the sales of the right hand model achieve a high enough level so that the 8% rule works financially. what do I mean by the 8% rule? No left hand version of a clubhead model has ever sold more than 8% of the units that the right hand version sells. Yet the tooling die and inventory cost for making a left hand version is the same cost as for the right hand version. Thus we have to see if the sales of the right hand model can be high enough to where 8% makes sense in terms of being able to justify the cost to make the left hand version. but we shall hope so.

      if you still need a fitting recommendation, I would strongly recommend Richard Kempton of Simply Golf in Hadlow, Kent. Yes that is about 40 miles from you and yes there are some fitters who are closer, but I always recommend Richard when someone is within an hour by car because plain and simple, I think Richard is the #1 best clubfitter in the world. I’ve known him for 30 yrs in this business, I have spent hours and hours with him in technical disscusions and there is no one I ever talk to in this business who knows as much as he does and has as much fitting experience. he’s the best and if there were 1000 more like him in the world, then custom fitting would rule the planet and there would be no retail golf stores selling clubs off the rack.

      Single length can work for every golfer because the concept is to make all irons have the same exact swing feel to allow for better shot, swing consistency. And to make the lower loft irons easier to hit more on center because in single length these irons are probably shorter in length in the single length set than they were in the conventional set.

      BUT. . . . . . . you still have to fit the set makeup of the single length set SMARTLY for the golfer’s ability. You are well aware in conventional sets of a #3 to wedges, not every golfer should own the 3 iron, or 4 iron, and many should not have the 5 iron. Some should not even have the 6 iron and should be using hybrids or high loft woods above that iron that is found to be the golfer’s lowest loft iron that they can hit well enough to get well up in the air to fly.

      The trend to very low lofts in irons over the past 30 yrs has gotten to the point that many golfers just can’t hit lofts under 28* with conventional lengths, well enough to even have them in their bag. it’s no different with a single length set. In general, the slower the swing speed and the higher the handicap, the higher the number of the first iron in the set makeup with hybrids or high loft woods above that.

      This would be the ONLY proviso in terms of golfer ability vs single length use. of course all golfers then need to be fit to the right shaft, swingweight, lie, grip size – that’s a given.


  219. Having taken up the game in my sixties not being athletic: I am at a loss as to whether I could benefit from your clubs? My Driver clubhead speed is in the mid seventies and I’ve gone to ladies shafts . My age is now 86. Ive never broken 90, so you’ll probably say “give it up”. I stlll enjoy humiliating myself and hope to for years to come. Thanks for any feedback. Frank
