Sterling Irons® Single Length Set


Wishon Golf has used its design and engineering experience to create the most technologically sound interpretation of the identical feel concept of single length set design with the Sterling Irons® Single Length set. The benefit of single length construction is better shot consistency achieved through each club in the set being the same length, same shaft weight, same total weight, same swingweight, same balance point to offer the same exact swing feel for each club. But with that in previous single length sets has come a loss of low loft iron distance, too much distance in the high loft irons/wedges and a compressed distance gap between clubs. Sterling Irons® offer the best in single length design by matching high COR face technology to deliver the right distance in the low loft clubs, with a shorter 8-iron length for the single length to ensure proper distance in the high loft clubs. Sterling Irons® single length is a fascinating departure from traditional incremental length sets to potentially offer improved shot consistency for all golfer types.

Tom talks about the Sterling Irons® Single Length Set


  1. I have been playing golf for some time with a hodge-podge set of clubs made up from a number of purchases over time on the cheap. I have obvious gaps between my woods and hybrids, hybrids and irons, and irons and wedges. I noticed that Sterling irons can be purchased down to LW, so that could greatly increase consistency and eliminate one of those gaps, but I wonder why you only offer a hybrid in #5 and not #4 or even lower? having a set that continues on to lower loft hybrids would eliminate another gap for me; I fear eliminating only one at the short end where compensating is easier might make such a large purchase risky. Can you explain the logic of why the Sterling set only goes to a 5H and give me any advice you can on improving my game on a fairly tight budget (I just can’t afford to get fit for and buy new hybrids and woods as well)?

    • LEE
      Thanks very much for your interest. With EVERY set of irons, the lower the loft, the more clubhead speed is needed to hit the ball HIGH ENOUGH to make the shot carry a full club longer than the iron just above it in loft. The different distance each iron is hit comes 85% from the loft but 15% from the length. So there comes a point in a single length set where if the golfer does not have a high enough clubhead speed, he has to be very careful to know what loft his speed will still hit high enough to fly and carry the proper distance. For example, to be able to hit the Sterling #5 iron a full club longer than the #6 iron, the golfer has to have a clubhead speed of around 75-77mph with the irons – that equates to a carry distance of around 150-155 with a normal 7 iron. And to be able to hit the Sterling #4 iron a full club longer in carry distance than the #5 iron, the iron speed needs to be 85mph or higher which relates to a normal 7 iron carry distance of 165-170 yds. If you have a clubhead speed lower than these cut offs, then you should not include the #4 and or #5 iron in your set.

      The hybrid only helps a tiny bit in terms of having a lower center of gravity to help make the ball get up to fly and carry. The Sterling #5 hybrid is still always fit and made to be the same length as all the rest of the irons. So it still is subject to virtually the same clubhead speed cut offs when determining the best set makeup for the golfer. We did not include a #4 hybrid because at the shorter single length, that 19* loft still requires a clubhead speed with the irons of 83-85mph to make the ball fly a full club longer than the #5. We know from experience that most people who do have a high enough clubhead speed to hit the 19* loft of the #4 would prefer an iron over a hybrid. Therefore, we chose not to design a #4 hybrid as part of the single length Sterling IRons.

      If you would find that your lowest loft Sterling Iron would be a 6 iron, then the club above that would not be part of the single length set and would be a hybrid of 24* loft made to a length that would be +1.5″ longer than whatever the best length of the single length irons is for you. If you find that your lowest loft Sterling Iron would be a 5 iron, then the club above that would also not be a part of the single length set and would be a hybrid of 20* made to a length that would be +2″ longer than your best fit length in the single length irons.

      Single length’s plusses are that all irons have the same swing feel, same swing plane, same everything to encourage a shot at better swing consistency and shot consistency. Single length’s only downside is that the golfer has to understand he probably will have a set makeup that will include one less low loft iron than he was used to having with his conventional length set. This really is no downside, it just requires an understanding and acceptance that the set makeup has to change a little from what the golfer was used to with a conventional set.

      Hope this helps, and thanks again for your interest,

  2. Dear Mr. Wishon,

    Greetings from India and wishing you a very happy new year.

    I am a beginner in Golf and have my heart set on the Sterling Irons. I have been holding of on the purchase till i am a bit more settled in my swing. Have been tinkering with my present clubs to find what length, grip size, weight suits me. I have even tried a 36″ 5 iron. I Seem to have a peculiar “problem”. I am only 5’9″ floor to wrist 31.5″ and have found that with my swing I can control and hit accurately my long irons particularly my 4 iron (it is a 15 year old hand down club- 38.5″, 59 degree,steel shaft,185 yards) better than any of the short clubs (I seem to have a inside to square path and hit a high Push/Push fade and I rarely if ever hook the ball) . Is it viable to do a one length to these specs. Am also apprehensive if a long shaft pitching wedge works, but do not have the baggage of being used to a short shaft and am a blank page in that regards. (am planning to have a 38.5″ long pitching wedge made which would obviously be heavier than the 4 iron but want to see the effect of length). In my mind my sterling set would be a 4 iron length from 4 to gap wedge, with the sand and lob being a separate shorter set only for very close in shots and since It might be difficult to play a long club in the bunkers.

    P.S. – Was also awaiting your one length Hybrids but I guess that is on the back burner now.

    • MANU

      Thanks very much for your post from all the way over in India !! It never ceases to amaze me at how much this game can convince people from all over the world to participate and have fun playing the greatest game on the planet !! And thanks so much for your interest in the single length Sterling Irons.

      It is both not feasible and not advised to try to build a set of single length irons to a length as long as 38.5″. For one, in a single length set, all the clubheads must be the same production weight. For a length of 38.5″ that would require all the heads to be around 247 grams and no where will you find a full set of #4 to the wedges in which all the heads are that light. And it would not be possible to alter an existing set of iron heads because most of the heads would need to be reduced in weight substantially which is just not feasible.

      Second, the main problem even if you did have the lighter weight heads to build the set would be the difficulty in controlling and hitting the 8, 9, PW, GW and SW irons in the set. 38.5″ is around 3″ longer than the wedges in a conventional set of irons and 2″ longer than the standard length of the Sterling Irons. That much more length would create way too much distance and height with the wedges and would also bring about a drop in control and accuracy. One of the main reasons I designed the Sterling Irons based on a standard of 36.5″ was to make the wedges be easier to control in a single length set.

      Granted, a possible drawback to using the shoreter 36.5″ length for the Sterling IRons is the fact that at that length, some golfers just won’t be able to generate enough clubhead speed to hit the #4 and even the #5 irons high enough to carry to a full distance. But in such cases we always try to teach the clubmakers to carefully evaluate the golfer’s clubhead speed with the irons so they can identify those golfers who do not have a high enough speed for the #4 and #5, to then be able to offer a proper set makeup recommendation. And then to properly advise on how to make the hybrids or woods that would be used above the lowest number iron in the Sterling set that the golfer can hit.

      Even if a golfer ends up with a Sterling Iron set that starts with the #5 or #6 irons, that still makes the single length set have 7 or 8 irons that all will be of the same exact swing feel and all which would be played with the same stance, ball position, and swing plane for achieving more shot consistency.

      thanks again Manu for your interest and we wish you the very best as you continue to keep working on your swing to enjoy this game more and more,

    • Tom. I have your hybrid irons for 5,6,7 irons but 752tc for 8 thru SW. 8 iron is 36.5 in length. Can I replace only hybrid irons with sterling irons. I really like 752tc. They work well for me. Just a thought

    • Anthony

      You could use the Sterling #5, 6, 7 and make them the same 36.5″ length as your 752 #8 iron. The Sterling iron heads are all designed to be 274g as spec weight with the same weight bore below the shafting bore that all my heads have for final swingweighting purposes. And there is an optional #5 hybrid in case you would prefer a hybrid over an iron head for the #5 club in the set. 5 hybrid and 5 iron are the same 274g and same 23* loft so they are an either/or option for players.


  3. Dear Tom,

    I have received your email that you have clearly sent to my attention by registering my presence on your website.

    For several months I’m interested in reading reviews and any information I find about your Sterling single length set. I’m really curious and very interested in trying them out. Unfortunately, however, I do not have a fitter nearby using your new technology (I live in Switzerland).

    However, I could see that on your website there is a chance to do an online fitting that uses different features to best fit every physical difference.
    So I was wondering if you have a new Europe-based store that can send me the set and whether the 90 days to try the set and see if it’s right for me, are always valid? If it does not fit me, how does it work for the return?

    Thanks for all your inventions and your endless dedication to this magical sport.


    • MARCO

      The most extensive and thorough on line source for the Sterling Irons would be . They offer the irons only in custom fit form. The golfer has the option of inputting all the specs for his set, if he knows what specs he needs from his previous equipment experience. Or the people will offer the golfer a series of fitting information questions to answer from which the golfer’s fitting specs for the set are determined. They do a pretty good job because the people doing the fitting analysis have a lot of experience analyzing golfer information to determine the best specs. For this online business, the clubs would be custom made in the USA and shipped to you from the USA. They do have a money back guarantee. If within the 90 day period you decide you do not want the irons, you send them back and sterlingirons will give you a 75% refund on the original cost of the clubs you paid. The reason they have a 25% return fee is because every set they make is custom. Therefore they cannot be re sold without a lot of effort and trouble.

      I hope this helps,

  4. Dear Tom, I’m playing your Single Lengths irons from LW to i4 for a few months now. They are really great clubs, I love them!

    I was wondering if it would make any sense to play a driver also with a shaft length of 37 inch?

    Under top conditions I hit mit iron4 180meters (carry) from the tee. My best ball flight is a straight slightly pull. My worst is a small slice with the long irons and a pull hook with the short ones. With my driver I always hit a heavy slice (pull & push!), so at the moment I got no woods in my bag. I only play the Sterling irons.

    • Christian

      It just would not work to try to play seriously with a driver at a length of 37″ or for that matter, less than 42″ unless you just do not hit a driver at all anymore because of struggling so much with it that you have given up on it. For a fair number of players, once you drop the driver length below 43″, you begin to lose so much clubhead speed from the loss of angular acceleration that you will see a significant drop in distance. With proper weighting of the much shorter driver you would hit it more accurately. But very few golfers can accept it when they see their distance drop by even as much as 10-15 yds. For ALL golfers, playing a driver at a length of 37″ would for sure bring about a significant loss of distance. In addition, driver heads are made to a weight range that accommodates lengths of 43-45 inches. At lengths shorter than that you could not add enough weight to the head to enable the club to offer even a reasonable amount of head weight feel during the swing. That in turn would bring about more inconsistency.

      Since you slice/push the ball, what you need is to be fit by a good clubmaker into a shorter driver perhaps of 43″ but very much so to have that head be ordered for you with a much more closed face angle to reduce the slice tendency. You probably have not heard much about driver heads made with a closed face angle because none of the big golf companies offer that as an option. Thus I recommend you go to the FIND A CLUBFITTER search tool on our website and put in your location to see if there is a good clubmaker near you with whom you could work to be properly fit for a driver as I mentioned. The link to find that clubfitter search tool is right at the very top of our home page.

      Hope this helps,

  5. Dear Tom,

    I am a 3 HDCP with a high swing speed. 7 iron will be around 90 MPH. 1 degree up right and I am Left Handed. Is the 4 iron available? If not can I use my Adams Idea Pro 4 iron I have now and have the shaft changed to the same specs as the Sterling’s 1 legnth?

    • MIKE:

      I am sorry but because we know the demand for a left hand 4 iron would be very small, we did not create the tooling to manufacture the left hand sets with a 4 iron. 31 yrs in clubhead design and I still feel bad when I have to explain this to a left hand player. In my career not once have I seen a left hand model achieve more than 8% of the demand it will in its RH version. When you tack on the fact that a 4 iron in the Sterling set should only be used by a golfer with a 7 iron speed of 85mph or higher, that lowers the demand even more.

      To try to use the Adams 4 iron with the Sterling set would require a bunch of weight to be added to the head after the 4 iron head is built to the same length as the rest of the Sterling irons. I do not know your height or wrist to floor measurement to advise whether we would recommend an 8 iron length (36.5) or 7 iron length (37). but if your best length were a 7 iron length, that 4 iron head would likely need to have at least 18 to 20 grams of lead tape added to make its swingweight compatible with the other single length irons at that 7 iron length. While that sounds daunting, at least the weight addition can be done. it will make the 4 iron head look a little odd with that much weight added, but it would be playable.

      Thanks for your interest,

  6. Hi Tom, I have been playing a set of Sterlingirons for a couple of months now and I’m still struggling with them. Alltough I have a clubhead speed of 90mph with an Callaway XR Iron 5, I have difficulty getting enough height on the Sterlingiron 5 and 6. I’m also struggling sometimes with a really deep downswing and hitting the ground before the ball – way more often than with my old clubs! Ballflight is a slightly Push Slice with the lower irons and sometimes a hook with the PW. When I shoot from an uphill position I have a high and straight ball flight, even with iron 5 and 6. A clubmaker made the sterling set for me with an additional weight in the clubheads (I guess 3 or 5 gramms) . Shafts are S2S Black. Some friends tried my clubs and can’t hit a single ball with them. I’m asking myself if something went wrong in the fitting – is there a way to check this?


      In 16 months and over many thousands of sets, I/we have yet to hear of a case when ALL of the other people who try to hit a set of the Sterling irons do not like them. That’s a first and I am not making this up for the benefit of this thread. It makes me think from my 6th sense in this industry that perhaps the irons were made with a swingweight that does not fit you very well or else the shaft does not fit you very well. Most people with a 90mph swing speed with the irons do not opt for a graphite shaft down at 85 grams. But at any rate, the thing to do is to go back to the clubmaker and explain that you can’t hit the irons very well. Ask him to work with you with one or two of the irons to re weight them first, then possibly try a heavier steel shaft to try to work your way back into better performance with them. It is the clubfitter’s responsibility to work with you to get things right to your satisfaction since the transaction for the clubs is between you and the clubmaker. It has to be a fitting matter because we just have so many positive responses and testimonials about the performance of these irons.


    • Dear Tom,

      I’m sorry if I said something wrong. My two friends, who tried the clubs, are beginners as I am. All I tried to say is that maybe the swing weight could be very unusual. But I went to a pro last weekend who tried my Sterlingirons and he said, its all fine with them. Instead he told me to put the ball a little more to my left foot in the stand for the iron 5 and 6 and that seems to work. As a beginner my golf swing is full of crap and I still make a lot of mistakes. When I bought the Sterlingirons, I thought Golf would become a lot easier. But it is a still a very difficult sport I guess. And all the training and hours at the range don’t protect me from embarrassment on the golf course 😉 And by the way: The club maker is really nice and was always there for my questions, but he is totally convinced that he builded the perfect clubs for my swing. Best regards, Christian.

  7. Hello

    I recently started hitting the Sterling single length irons and have been very pleased. I am a women golfer with a 15 handicap and have found the irons to improve my consistency greatly. The clubs were designed as a strong senior shaft almost regular shaft. I had the set built GW-7iron. The plan is to supplement the rest of the set with hybrids. However I am having trouble With the hybrids of greater length. I have been trying various custom demos to get the feel right. The step up from the 7 iron is about 1/2 inch in length with a 6,5,4,3,2 hybrid. The SL clubs are built at 36 inch. I am hitting my 7 iron about 145 But when go to 6hybrid I jump to about 170 distance. But mostly the feel is not there. Will you be coming out with SL hybrids to match the iron set ? Would you recommend the hybrids all at the same length?! If so what length? Is changing length from the irons to hybrids just something Thant needs lots of practice?

    I appreciate any advice you can give. And love my new irons!

    • Hello Patty, and thanks very much for coming to our site with your question. I’m pleased to hear you like the new Sterling irons and with your 7 iron distance at 145, you must have a very good clubhead speed and swing characteristics. That’s great.

      It’s very tough to answer your question without some more information, mainly that being precisely what length and loft your #6 hybrid is. Shot distance is all about clubhead speed + loft and a little bit of face design involved too. I am not sure but are you saying that your 6 hybrid is only 1/2″ longer than your Sterling 7 iron? Do you know the loft of this hybrid? The model name/brand so I could have a chance to know what the head construction is like?

      Your 7 iron is 36″ as you said and the loft is likely 31* since that is the spec. It also depends on whether the clubmaker who made your irons checked and verified that loft. But at any rate, in most cases for this 6 hybrid to hit the ball +25 yds more than this 7 iron, it would need to be a good bit lower in loft, say in the realm of 25-26* AND at the same time be at least an inch longer than your 7 iron. So if there is anyway you can get back to me at with more info on the loft and length of each of your hybrids, that would help me make a better recommendation for what you might do.

      I am toying around with a combination set of single length hybrids and fairway woods but as of yet, I have not finished it or gotten to the point of being ready to tool it up to manufacture it. I would like to combine the woods and hybrids at one length so in matching with the irons, there would only be one length for all the irons for a golfer and then one other length for all the hybrids AND woods for consistency sake.

      Also, if you can let me know, where did you get your Sterling irons and where did you get your hybrids?


  8. Hi Tom,
    I fully understand the concept of single length irons all the same length, swing weight and lie angle, however traditionally wedges have tended to be 2 or more swing weights heavier than the rest of the irons. Would it be wrong to build the pitching wedge, gap wedge and sand iron heavier ?

    Many thanks

    Bob Frost

    • BOB:

      You’re absolutely right in saying that traditional wedge fitting has ordained that the PW and GW may be 1-2 points higher than the swingweight of the numbered irons, while the SW is typically 3, 4, 5 points higher. This has been the norm because of the fact that golfers hit a higher percentage of less than full swing shots with the wedges than they do with the number irons. Less than full swing shots it has been felt could benefit from a timing standpoint on a slightly higher head weight feel during the swing.

      With single length, as you say, the whole concept is based on duplicating the same swing feel in each iron, all the way through the set. That in turn is said to be able to breed a higher level of swing repeatability, from which better shot consistency could happen. So this is how everyone should begin if they make the move into single length irons. Then from there you see how you fare with the wedges and make any adjustments based on your experience over several weeks or months of playing with and hitting shots with the irons and wedges.

      What we have found so far is that the more experienced the player or the more feel sensitive the player or the more the player was used to their old SW, the more they might tend to shift some things with the wedges, usually only the SW though. Some will increase the swingweight slightly, and some even have chosen to go back to their shorter and old SW that they were totally used to, but leave the PW and GW as part of the single length set. Now in saying this, I am estimating that this might mean around 15-20% might make such an adjustment to the SW while the other 80% seem to adjust to being fine with the SW as a part of the single length set up for everything.


  9. Hi Tom

    I love the Sterling irons. I hit the 5 iron 170-174 yards. What specifications woudl you recommend for my next clut up to hit 185-190 yards. If you had a 21 degree Sterling hybrid head in stock, would that work?



    • BRUCE

      Thanks for your post and we’re very pleased to hear you like the Sterling irons. I must say in 31 yrs of designing head models that it has been a real pleasure for me to have heard so many positive reports from players who have moved into the single length irons.

      While we do have a 19* #4 iron now in the Sterling set, I would not recommend you try it because at a 5 iron distance of 170-174, I don’t think your clubhead speed is enough to properly elevate the shot with that loft at the Sterling length. Rather, I would recommend you think about either a 20-21* loft hybrid at a length of 38 to 38.5″, or you could consider a 21* 7 wood made to a length in the range of 39-40″.

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

    • Hi. I hit my 5 iron 170 and my Sterlings are graphite shafts. I’m 5’7 and swing in low to mid 80s…. my clubfitter built me the Wishon 7 wood at 39.75 with complimenting shaft and I hit it 185 consistently…. opted for the 4’wood and 11*’driver to match…. the 7 wood is my favorite…. kind of a cross between a hybrid and a wood…. it is money on tight fairways and approach shots. It’s well worth a try….

  10. Hi Tom,

    I’m interested in back weighting my sterling irons. The shaft is your S2S White in stiff at 37 inches. Are the tour lock pro counter balance weights compatible with this shaft?



    • Jaime

      I just re checked that in my shop with a ctrwt and White S iron shaft and the weight will fit nicely in the shaft. Not a problem.

  11. Tom

    I played single length Sterling for 8 months. I found that I had great difficulty getting enough height on the 5 and 6 iron and way too much distance with the 9 down. I tried shorter length at 36.35 and found this did not help much in the shorter irons and made the long irons nearly impossible to get airborne.

    Out of frustration because I believe in the concept, I decided to put standard weight irons on 37 inch shafts. I cut the shafts to get the frequency close as possible and I was amazed. I hit a 3-PW, GW, SW and all are the same frequency but not the same swing weights. As you know the long irons are much lighter than the short irons. However I now get great height with all the clubs and my 3 iron carries 215 and my sand wedge is back to 105 carry. All the irons now have a perfect trajectory.

    Now I know this is all counter to the same length concept but it works. I am 67, swing speed is 103 with a driver and I play to +1. I’m not sure why this works as well as is it does but I have let three other single digit handicappers try them and they had much the same success. I had a 15 handicapper try them and he hit the 5 iron great but not the 3 and 4 and his wedges he lost 2-3 yards each according to his analysis.

    The wedges do feel a little heavier but I believe that is what has slowed down the club head to keep the distance more normal for me. I would appreciate any input you might have into this.


    mike miles

    • MIKE

      The reason that you would not be getting the height and carry distance with the 5 and 6 iron is because your clubhead speed at the shorter single length is not as high as it was with the longer length you would have had for these numbered irons in your conventional set. Club length is a key element in clubhead speed and better players like you who certainly would have a late release would see that for each half inch the single length irons are shorter than the same number in your former set, you would be losing about 1 to 1.5mph in speed. So with a conventional length of 38″ with a 5 iron in a normal set and a 36.5″ length for all the single length irons, that would be around a 4-5mph slower speed with the 5 and 6 in the single length set. It also must mean that with your single length irons, you are probably around a 70-75mph speed. From our testing, 75 is enough speed to get full and proper distance from the Sterling 6 iron at 36.5″, but the 5 iron with its 23* loft at 36.5″ needs closer to 80mph to fully elevate it to get full carry distance.

      The other possibility is if you happen to have a little steeper downswing into the ball, AKA more of a downward angle of attack. If you happened to hit balls on a TrackMan or FlightScope monitor, look at the readout for the Angle of Attack. if it averages more downward than minus 3* then that means you would be a little too steep and would be de lofting what is already a lower loft on the Sterling irons to cause the lower shot. If the 15 hdcp hit the 5, 6 irons higher than you, then he either has a higher clubhead speed AND/OR a less steep angle of attack into the ball. Since you have a driver speed of 103, my bet is that the lower flight is coming from you having a little more steep A of A into the ball with your irons which delofts the face at impact.

      For the higher number irons, there you are getting to a point that the length of the single length is starting to get to be a little longer than what these same numbered irons are in your conventional lengths set PLUS the fact that the lofts may be lower in the Sterlings than what you had for lofts on your former set. You being a low hdcp good player, you may very well have been using a conventional set with lofts that are not all that low compared to what so many game improvement irons are today. For example, in a traditional forged set the 9 iron would be 36″ in length and probably around 42* loft. The Sterling is 40″ loft and if it was made to an 8 iron length, would be 36.5″. Those two things are why you would be hitting your 7, 8, 9, PW longer in the Sterling set than you probably hit the same number irons in your conventional set.

      What you can try is to have a good clubmaker bend the lofts a little higher on the STerling irons so the lofts help you get the ball more up with the 5, 6 but drop a little distance with the 7, 8, 9, PW. I’d say to do the lofts at 24, 28, 33, 38, 43, 48 for the 5, 6, 7, 8, 9, PW and hit balls with that for a few range and playing sessions to see how you feel about that.

      Thanks for letting me know so I could help a little,


  12. Hi Tom…

    Still eagerly awaiting the May release for these in LH. I’m planning a full spread of 6-SW with a 5 hybrid. This is my question for you today regarding gapping. I have a Ping G30 hybrid at 26* and stock length that I really enjoy. The differences between the longer shaft and higher loft VS the sterling at a shorter length and lower loft… Do you believe for gapping these would work out to roughly a similar yardage?

    I’m certainly not opposed to a shorter hybrid as it could be very versatile around the green as well. Just wanted to see what you’re thoughts were.

    Cheers and thanks again!


    • JEFF

      Thanks but I have a little bit of an OOPS to say to you because we did not tool up the 5 hybrid in left hand – the left hand set will be offered in the 5 iron to SW. The hybrid in the RH sales just does not sell very much at all. NOt even one of 20 sets are bought with a hybrid for the #5 so when we have to apply the normal math of 8% for the left hand demand, it unfortunately said that there just would not have been enough left hand demand for the 5 hybrid to merit the investment in the tooling and production inventory. I am sorry but I do hope that the rest of the LH set will be acceptable to you.

    • Hello Tom!
      Two questions on the Left Handed Sterling irons.
      1. Do you have an exact release date?
      2. I have been playing 4 wedges for several years now.
      Current set lofts are 47,51,55, and 59. Since a gap wedge is not available, would you recommend having two sand wedges and bending one to 58 or 59 degrees?

    • Philip:

      there is an old saying in my work that says there is no such thing as an exact release date for any new model because there are always little glitchie things that can happen to delay things ! But we do have a quoted ship date of May 23 for the first production of the left hand Sterling irons, which would make them available around June 1. if nothing delays them between now and May 23. . . . . which is possible when you are talking about a brand new model never made before.

      At some point in June we will also have the brand new Sterling SW and LW. I felt that I wanted the SW to be more of a traditional shaped SW than to look like one of the irons. So I did a new design and those new SW’s will be here around mid June in RH and in LH. There will be a new LW to match that which will be in RH. Very sorry we can’t do that in LH but the numbers of demand in LH for it just could not add up to allow it to happen. if you did bend one of the LH sand wedge heads to 58-59, you would increase the bounce to 15-16* which might be more than what you have been used to in the past for that club.


  13. Hello Mr. Wishon. i have been reading a lot lately about SLI and have had the chance to hit Cobra’s new single length forged 5, 7 and 9 irons. i also have a friend who had a SLI set built using Mizuno MP25 iron heads and lots of lead tape on the longer irons and some grinding to get weight down on the shorter irons. i found i loved how easy it was to hit his 4 iron and the Cobra 5 iron at the shorter than normal length, but had a lot of issues with the shorter irons in both sets. i was hitting them really high and contact was far from good. i understand it would take some adjustments and practice to get used to the shorter irons being longer and over time/practice i could probably make the necessary adjustments.
    i am curious though on your thoughts of doing single length (say 7 iron length) for the 4-7 irons and then going normal length for 8- the rest of the irons/wedges? I understand that lofts may need to be adjusted throughout the set in order to get the correct distance gaps, but was just wondering what you thought of this idea? thanks so much!

    • Chris

      There are for sure many ways you can alter the length progression in irons from the norm. And if you spend the time to make sure the shaft, weighting, lies and everything else are really well fit to the golfer, they can all work well to help a golfer get a little more consistency from the irons. No question about that. What single length does that no other concept does is two things – 1) it perfectly duplicates every single thing that has an effect on swing FEEL of the clubs for every club. From that comes a better chance for a more repeating, consistent swing motion. 2) it makes each iron so you play it with the same stance, posture, ball position, swing plane – so like you are hitting the same iron for every shot in your conventional set. From that also comes a better chance at swing repeatability and shot consistency.

      When you deviate from the single length, you deviate from this identical swing feel for each club and you deviate from the same exact everything with the set up and swing. This is not to say it is a guarantee you’d be less consistent with a set that deviates to two lengths or some other configuration. It is possible to get other length set ups to work better than does the normal incremental length sets everyone makes.

      What you experienced with the cobbled together set of Mizunos with the high loft irons and wedges is probably because you went with a length that was longer than what I chose to do with Sterling for that very reason. All single length sets before mine chose a 6 iron length. Why? Because they knew they had to have at least that much length to get enough clubhead speed to have a chance to hit the lower loft irons far enough in comparison to the same irons in a conventional lengths set. BUt with a 6 iron length, your wedges are now 2″ longer than what you had in your conventional set. That not only contributes to ballooning the height of the shot, but it makes accuracy and consistency suffer too from the wedges being too long.

      I chose an 8 iron length because, 1) I knew this would put the wedges at only 1 inch longer than what most golfers were used to, so that would make this control issue easier to manage, 2) I knew with my design history that I could use a thin, high COR face in the low loft irons to bring back ball speed that would otherwise be lost with a normal low COR iron from the 8 iron length being 1.5-2″ shorter than what the low loft irons are in a conventional set.

      Cobra used a 37.25″ length because they too knew that they did not have the ability to push the COR as high in the 4, 5, 6, 7 as I can in my Sterling 4, 5, 6, 7. So Cobra is trapped into this situation where to get enough distance in the low loft irons, they make the high loft irons and wedges too long for most golfers to be able to play well with. So if you do that, you ruin the concept of perfect duplication that single length depends on to work better than a conventional set.


  14. What club fitter for the Sacramento, CA area?

    • JASON

      Unfortunately since Scott Herringstad closed his shop in the Sacto area, there is no one with the depth of fitting knowledge and experience that I feel is necessary to do the best job in fitting for a golfer. That being the case the two very best fitters closest to you are both in the Bay Area, about 60 some miles from you. Michael Clark of Fore Seasons Golf in Berkeley ( 510-841-0972 or cccthebear@gmail.com ) or Stan Morovia in San Rafael in Marin County at the McInnis Park Driving Range off 101 ( 415-492-1800 or stan@marinclubwerx.com

      Both these men are truly in the top echelon of professional clubfitting in this country and I mean that. It might be a pain to take the drive but it would be worth your time to do so with either one of them. Thanks for your interest,

  15. Club fitting in Canada?

    • MIKE
      Yes, there are some extremely knowledgeable clubfitters in Canada. Not everywhere though. I strongly recommend you head back to our website at and right in the middle of the home page, click on the image for FIND A CLUBFITTER. There, input your city/town and province and it will tell you the clubmakers who are closest to you. If there are several, email me at to tell me where you live and I will tell you who is the best. If there are not any close to you, which can happen, then the options would be to contact one of the clubmakers by phone and see if he can do a long distance consultation fitting for you. Some of the clubmakers are very good at interviewing the golfer deeply enough to know what they need to know to do a credible job in the fitting.

      Hope this helps,

  16. Any club fitters in or near Milwaukee that you recommend for Sterling custom fitting?

    • ERIK

      Not directly in Milwaukee unfortunately, and I am not sure why. Milwaukee is a big golf town and there should be a good clubmaker there but in terms of someone I know to recommend based on solid experience, I don’t have a person right there. Closest one I can personally vouch for from my experience and contact is Scott Starks in Madison. Scott’s very good with a good depth of knowledge and experience in the field.

      Thanks very much for your interest and I hope this helps,

  17. Tom, as a club designer I would like your opinion of the PXG irons? I know they are extremely expensive and the designers were only given 2 parameters by Bob Parsons: 1. money is no object, 2. time is no object, I want the best clubs money can buy! Did they achieve that? I’ve read that most club mfgr’s only use about 3 manufacturing processes, and PXG’s use about 12. Does this justify the cost? Are their processes trade secrets, or ones that other mfgr’s have chosen to skip?

    • RON
      It’s a nice iron made by a very good production factory, but there are other high COR irons out there that are just as good or long and which cost a lot less. There’s a lot of unjustified hype surrounding PXG in my opinion. They are very well designed and very well made but not worth that kind of money.

  18. Tom, you and I chatted a couple of years ago regarding the Sterling clubs and you said if I was willing to come to Durango you could fit me yourself. Well, that trip probably isn’t going to happen anytime soon, so I was wondering if The Clubfitter in Pasadena, CA. would have the same S2S and clubfitting ability as you? I know you said you probably have the largest shaft technology database anywhere and I wondered if The Clubfitter would have access to that level of database info? I just feel that if I’m going to make the investment in new Sterling clubs that I’m getting the best shaft for my swing.

    • RON
      You would be in VERY good hands with Bob Williams who is the Pasadena Clubfitter. I have known him for a LONG time in this side of the business and I can guarantee there would not be 5 guys who know more than him. Besides, I retired on Oct 1 and to correspond to project work I am doing now in my semi retirement, I renovated the R&D building so I can’t do fittings there anymore. Bob’s good – give him a call.

  19. Are all headweights exactly 274 or do they vary a little?

    • Jaime
      Every clubhead ever manufactured for any company has a tolerance of +/-3 grams from the specification weight. The spec weight is 274g for each Sterling head with a production tolerance of +/-3 grams. I monitor this very carefully and I can tell you that the real tolerance is running more like +/-2g, but the vast majority come in between 273 and 275g. Every Sterling head is made with a weight bore located at the bottom of the shafting bore. This weight bore is there to accept specially made weight plugs so clubmakers have a way to achieve the final swingweight they desire based on whatever shaft and length and grip weight they used in the assembly.

  20. Mr. Wishon,
    I am now getting older, and have lost distance and club head speed. I want to play with less 14 clubs with wider loft differences between clubs. I am very tall, 6’-5”. I play with Pings that are maroon dots, their, most upright lies.
    Can you make a set of single length set of clubs of 37.5” with the following lofts?
    30 degrees, 36 degrees, 42 degrees, 48 degrees & 54 degrees? Do you make a 30 degree club that is a hybrid?

    • CARL
      It would be possible to bend the Sterling irons to be the lofts you wish to have so you have a 6* gap. That is a smart move for a situation you describe for a drop in clubhead speed. The 7 could be bent from 31 to 30, the 8 from 35 to 36, the 9 from 40 to 42 and probably it would be better to use the GW to bend down from 50 to 48 so the bend is only 2*. Then the SW would be able to be moved down to 54 if you wish to still have substantial bounce on the sole angle of your 54 club. The lies could be bent to as much as 67* which would be +4 up over the spec for each head. A maroon dot is +4.5* upright so this would be close enough to not be a difference that could matter for your performance. The only issue would be the 37.5″ length. With the headweights at 274g, the swingweights would be a little high at 37.5″. But it would be possible to use a much lighter weight shaft which could be fine for you since you are losing clubhead speed and that could help to prevent the swingweight from being too head heavy at that longer length.

      The 775HS hybrid is a high COR face hybrid and in the #6 head, it could be hand selected on the order to be 30* loft. IT has a bendable hosel so its lie could be pushed up by as much as +4* up over its design lie spec of 61.5 to be as much as 65.5* for its lie. This hybrid could definitely be made to be 37.5″ and match the swingweight of the other irons because its designed head weight will allow for that.

      If you need help with finding a clubmaker in your area with whom you could work to obtain such a custom set, respond please with the name of your town/city and I would be glad to check and see if we have someone with good experience in your area.

      Thanks very much for your interest,

    • I have built 3 single-length sets at 37.5″ using S2S white shafts and 2 at 38″ using S2S blue. The customers (including myself at 37.5″) love them!

      Many people have posture problems with too-short clubs. Some are super tall with short arms, and others have structural issues that make it hard to stay crouched. In my experience, the ability to make the wedges long enough for a comfortable stance is even more valuable than making the 5 iron shorter. A less-crouched posture is a huge improvement for many people, and it gets even more important as we age and lose flexibility.

      The simple expedient of using progressively lighter shafts for longer build lengths has worked well for me. I no longer worry about the numerical value of the swingweight. When all the irons set up comfortably and feel the same, the golfer quickly adapts to whatever that feel happens to be, since they get the same feedback on every swing with every iron.

      It is easy to do an MOI match to any level of accuracy with a single-length build, but I doubt that most people will notice. You can obsess about adding just the right amount of lead at just the right place – and I do that for elite golfers – but for the majority of people, a single length set at the right length and lie feels just fantastic without any extra lead.

  21. Tom, I just built a set of sterlings at 36.5″ and a d1 sw. I have never seen this asked or mentioned, however I just assumed that all shafts are tipped the same (to an 8 iron spec). That just seems to make sense as an experienced club maker. Am I correct?

    Also, I have a lot of folks who want to try this set, including the club pro. Thanks Tom.

    • FRED

      Yes for sure, for a single length set in which all the irons are made to be 36.5″ in length, EVERY SHAFT IN EVERY HEAD gets tip trimmed the same, as if you are making a set of all #8 irons. This is all part of the potential benefit of a single length set to have EVERYTHING identical in each iron – same length, same shaft weight, same shaft flex/bend profile, same total weight, same swingweight, same balance point and same MOI.

      Thank you,

  22. HI, Mr. Wishon.

    Am a beginner from India and currently playing with an old used set of clubs. Have started getting better at the game and would like to upgrade. I really like your philosophy that a custom fitting can help a beginner, perhaps even more than a Pro. Also the logic behind single length irons make a lot of sense to me. Question is how do I get fitted in New Delhi. Do you have an associate/acquaintance over here that I can get it touch with. Thanks.

    • Mr. Kamboj:

      Thank you very much for your interest in proper clubfitting. I am sorry but there are no clubfitters that we know of in India yet. Perhaps that can change as the game continues to grow in popularity in your country. The best I can do is to recommend that you contact the people at Golf Shafts Asia in Ipoh, Malaysia. I believe they can interview you and find out enough about your swing characteristics and how you play that they could do a good job of coming up with proper fitting specifications for you and build a custom set for your needs. They also handle the Sterling single length irons in their business. The other option for the irons is to visit . There you can answer a series of detailed questions about your swing characteristics and how you play and we are the people who will come up with your fitting specifications, then custom build the set and ship them to you in India directly.

      I hope this helps, and the very best wishes to you in this great game,

    • Mr Kamboj – I am sorry but I realized I did not give you the contact information for Golf Shafts Asia:

      Golf Shafts Asia
      Phone: 60 546 5590 or 60 10 766 1412

  23. Tom
    I am 64 and like others am losing muscle strength and swing speed. I remember the EQL’s but never tried them. Are the Sterlings suitable for a 12 handicapper going up and could I get them with the Recoil shafts? Do you have experienced fitters available in the Edmonton Alberta area or in Northern Alberta? What kind of price could I expect for a set?

  24. Is the 4 iron Single length out? Someone on WRX mention getting a new set from 4-PW of sterling irons.

    Also how forgiving are the heads? Game improvement?

  25. if request for loft bend, will it permanent? im planning to buy a set with pw 44, gw 48, sw 52 degrees.

    Reason being, i currently play pw 44, 38 gap wedge, 52 and 56 wedges, which works pretty well for me on distance gaps. full swing carry distance would be at pw 44 degree 110yrd, gw 48 at 100yrd, 52wedge at 90yrd, 56 at 80 yrd and less.

    Im worried how distance gaps would work for me if i use the default sterling setting, pw 45, gw 50, sw less club…would like 10 yrd gaps for each clubs..

    • Justin

      Absolutely. With ANY iron, once the bend is actually made, it does not revert back. This is a myth that is perpetuated by some who do not really understand bending and metallurgy. Usually what prompts them to believe this is that they are unaware that when you bend any iron, the hosel will stretch and move a little BEFORE it reaches a point of being permanently bent. So if the person does not have a huge amount of bending experience, they can feel the hosel move and THINK it was bent, but in fact it was only being stretched/flexed and did not reach its point of permanent deformation, aka the actual bend. The heads for your set can most definitely be bent to whatever loft you wish to have. If your clubmaker is competent, he can do the bend. Otherwise when your clubmaker orders the heads from us, he should tell us what exact loft and lie spec he wants on each head and we’ll do that within 1/4*.


    • thx for the detail info!

      ordered the set with the above loft on!

      Look forward to receiving them!

  26. Tom I noticed on your web page there was not an option for Jumbomax grips I play the small size ones can you add those as an option.

    • DAVID
      If you are referring to the direct sales of Sterling irons through the website, please understand this is NOT our website. is a customer of ours and in their venture we do help them by providing the custom fitting recommendations for their customers. But we do not own that site and we have nothing to do with their sales policies of what they offer with their custom fit clubs. You would have to contact them directly to inquire about different grip options or you would have to have the grips installed on your own after you would get the clubs. Talk to them, they are good people and may be able to help.

  27. I recently had John Gamble at Carolina Golf Mfg. in Charlotte, NC assemble me a set of Sterlings. WE went with the 8 iron length at 36.5 and used Nippon NS Pro 950 Reg flex shafts. I am 68 and have lost a lot of my swing speed and like all golfers I’m constantly looking for anything to help my game. After a period of adjustment in which I struggled to make solid contact, I have finally gotten use to the fact that I can set up for every shot the same. Unless you make some major improvements, I’m probably playing with my last set of irons. Thanks

    • Phillip

      The Thanks are to YOU for taking your time to work with John for your fitting requirements. John is one of the most experienced clubmakers in the business and I have known him for many years in this side of the golf equipment business. His fitting expertise is a BIG reason that you like the new clubs because getting the right fit for each golfer’s unique combination of size, strength, athletic ability and swing characteristics is so important for the success of the clubs.

      Thanks SO MUCH for your support, for your interest in what we do and in professional fitting. The very best to you in this great game !

  28. Tom,

    I asked a question yesterday about clubs for completing a set of Sterling Irons. I just want to make sure I am clear on your response. I do need to add one little caveat. I have been fitted for a standard set of irons in the past year. My fitter was Mike Dickerson of Golf MD in Olathe, KS. He has a great reputation. Mike fitted me for a set of irons and recommended 1 inch over length w/ standard loft and lie. I am purchasing the 5 – SW Sterling Irons. With that said would you still recommend:

    23-24 degree hybrid with a max shaft length of 38.5 inches or should increase the length an inch?

    20-21 degree hybrid with a max shaft length of 39 inches or should I increase the length an inch?

    I suspect I would not want or like a shaft longer than 41 in the 5 wood or 42.5 in the 3 wood.

    Distance is not an issue with my game, accuracy is and I would not mind losing some distance with shorter shafts in order to gain as much accuracy as possible.



    • DOUG
      Please understand I was just offering a GENERAL suggestion because I had no idea you are working with Mike D. best thing you can do is to put yourself in his VERY CAPABLE hands for having him do his thing to continue your fitting analysis to offer you the best specs onthe other clubs beyond the Sterling irons. He’s there in person to see your swing, see your ball flight and do the fitting analysis the right way. We’re not so when we get what we think are general questions, we have to offer a general recommendation. Mike’s one of the best so let him do the analysis and the recommendation for the other clubs.

      Glad you told us you are working with Mike,

  29. Seems golfers can buy online ! Correct ?

      This is not our website. It is owned by a golf professional who pushed and encouraged me to design the Sterling irons. We do build the clubs for this direct sales website that the owner orders from us based on the sales he gets through the website, but we do not have any ownership of this venture. he’s done a nice job of promoting this website offering but it is something that every clubmaker could do if they so desired.

  30. Hi Tom…

    I’m very interested in these clubs… any chance they’ll be available in LEFT handed in the near future? I have a Wishon fitter/builder not 15 minutes from my house and I’d love to get into a set of SL irons.

    Thanks again,


    • JEFF

      Thanks very much for your interest – yes, this will happen but probably not until early spring of next season. We really need this year to assess the staying power of the model before we go into the investment in left hand tooling dies and production inventory. Never in my 30 yrs of designing have I seen a left hand model sell more than 8% of the units it does in right hand – so we just need to be sure of this being a solid trend rather than a fad before we expand it into left hand. Thanks much ! I would recommend that if you are interested, send an email to and tell them you are left handed and you wish to be notified when we do complete the model in left hand.


    • Thanks Tom. The golfers of Canada appreciate the left handed support!

      I’ll touch base with Dan at Dan’s Custom Golf in Hampton when they are available.



    • JEFF

      I am sure it will happen though probably not until early spring 2017. We got a little more of a push to do LH when a very famous hockey player from your country begged us to do this in left hand but I promised his agent I would keep that quiet !! HA!


    • Well I’m glad he begged for them. If you want a completely unfamous hockey player then I’m your man! Can’t wait until Spring. The irons like great.. a raw finish possible at all?

    • JEFF:
      We do see ALL golfers as the same – players who just want to have the most fun possible by playing to the best of their ability ! (How’s that for a positive spin on that comment I made I was kidding about !! ) We will get that done, maybe not as soon as all the interested left hand players may wish because the end of the selling season is coming soon and we don’t see it as a wise thing to intro a brand new model when the demand cycle is at its lowest of the year. So probably next year as the season is about to start. but I do have to be upfront and say no, the model won’t be done in a raw finish – in fact it can’t because of the high strength steel face in the #5, 6, 7. Proper heat treatment to get the face to where it needs to be strength wise does change the natural finish of the head to be almost “burnt” looking and not in a consistent appearance. Also, the high strength steel alloy of the face is very susceptible to rust simply because of the chemical composition of the alloy which results in its high strength – in fact all high strength steel alloys will rust if not protected in some way. For us with our HS alloy, we know that chrome plating offers the very best long term protection for the HS face alloy. So all the heads will forever have to be chrome plated which means an offering of either satin chrome, pearl chrome or mirror chrome as the finish options.

      Thanks much for your sense of humor and your interest !

  31. Saw your Video …nice ! I bought the custom set of one irons about 6 years ago and did quit well with them . I think they were cut to a 6iron … Your approch seems to have taken the one club process much further ! Do you not use the wrist to flood measuring way of customizing ? Just curious why yours are 8iron ? I have not all about you method so maybe I missed it ? But I am interested and they look much better to my eyes !!!! Beautiful .

    • TYLER

      I too was well aware of single length based on a 6 iron length. First time I saw it was 1986 from a Canadian company by the name of Iso-Vibe. All these previous single length sets chose a 6 iron length for one big reason – they had to have enough length to prevent the natural clubhead speed drop from being significant enough that the golfer could not hit the lower loft irons as far as the same irons in his old conventional lengths set.

      But with that 6 iron length comes something not so good – the 9, PW, GW and SW are all now quite longer than they were in the golfer’s conventional lengths set. 2″ longer. And that can bring a problem with accuracy and lack of distance control with this scoring clubs. Super good players like deChambeau can adapt to that. The 99% of the rest of us find it tough.

      So we chose 8 iron length for three reasons – 1) we knew it would make the 9, PW, GW, SW easier to adapt to, to be able to retain accuracy and have proper distance control; 2) we knew just about every golfer can hit an 8 iron more on center more of the time than they can a 6 iron; 3) we knew we had our high COR face technology to make up for the possible loss of distance in the lower loft irons at such a shorter length.

      Added up it really does work and the testimonials are rolling in now that we have been selling the model for 3 1/2 months. I’m 65, been designing head models since 1981, during which time I have designed over 350 different head models and sets. During that time I have been fortunate to have created over 50 different technology firsts in my head design work. But even so, I am beginning to think that the Sterling single length set may very well be the one single best clubhead set design I have ever done in my career. Not saying that for pushing sales and money – I have 6 other sets of conventional length irons in my design line and every one of those is a very good design, with two of them bordering on exceptional.

      But this Sterling single length is really something worth looking at for all that we were able to do with it, and mainly because we chose to do it with a shorter 8 iron length. That really opens the door to allowing the set to do what it is supposed to do – make for more consistency and repeatibility in your iron play.

      Thanks for your interest,

  32. I have long arms and need my clubs bent flat 3*. Is this possible with these irons?

    • Yes, we can bend 3* up or down easily. We’ve done a special set for a player in need that we were able to coax to 5* flat. Doubtful if all the clubmakers out there can do that because they don;t have the bending experience with this model that we do. So if you do go to a clubmaker for the irons, he can order the heads from with US doing the bending.


  33. Hi Tom, do you have a stockist or outlet in Austarlia? Thanks.

  34. I am a single digit handicap and am very interested in these irons. Are these more for novice golfers? I currently play muscle back blades, and wonder if these sterling irons would have a negative impact on my game? A lot of the comments I read have to do with high handicap golfers who love the variability of long irons removed. I don’t have a terrible issue hitting long irons, however, I do know the swing isn’t exactly the same.

    I am very interested, because from an engineering standpoint, these irons make sense. I have been looking at videos and reviews, and everything is positive, but I don’t know of any better players that have put them to play and what their thoughts were compared to a player’s iron.

    I am up for a new set of irons, and I want to seriously consider these before I buy.

    Any information would be helpful.

    • Sebastian
      It’s an interesting thing with golfers of different playing levels and iron models. A mid to high handicap player would be an idiot to try to play with anything but a high game improvement level iron while a low hdcp player can technically play with any iron model ever made as long as the rest of the fitting specs are all nailed down right for him. What it always comes down to with low hdcp players is a combination of personal preference for the shape/style/looks/offset of the iron with sometimes a very heavy dose of ego that once in a while can go with that. Sorry, no offense meant, just saying that some low hdcps play with irons that make the game harder just because of their ego.

      The golf pro who was the inspiration for me to design the Sterling irons by both bugging me for long enough to finally create them and for putting a few thoughts into my head about how I should create them is a very good player with a high clubhead speed who has played in a handful of European Tour events over the years. He plays the Sterling irons and went through US Open qualifying at Bethpage Red with his set this year. So the design is adaptable to any player, but in the end it has to come down to whether you like what you see on the end of the shaft when you put the club down in the playing position.

      Sounds like you need to see them and if possible, hit some shots with a few of the irons before you make any decision. To do that, head to our FIND A CLUBFITTER locator tool that is here at this link – Put in your location and the clubmakers closest to your location will show up. If there is one or more close enough to you, give them a call and see if they have any Sterling demos, and if not, whether they would be willing to get smart and get some (HA!). Take it from there and just see what you think.

      There is no question the Sterling heads are going to be a little larger than your muscleback blades – not hugely so, but they will be so this is one thing you have to think about. On the low loft irons in the Sterling set, they do have a tad bit more offset than most blades have, but here again it is not that much and not even remotely close to the offset you see on a game improvement set of Pings or Callaways.

      Feel will be different in the Sterlings vs any solid muscleback blade. That too you have to consider. But the other benefits are there, the ones you perceive from the engineering standpoint. So that might make a big difference in your thoughts as well.

      Thanks for your interest for sure,

    • Tom said: “…some low hdcps play with irons that make the game harder just because of their ego.”

      Oh, this is sooo the truth. I see guys all the time playing clubs that they (a) can’t take advantage of (like moving the ball left or right) and (b) can’t handle (because that movability also requires sacrificing forgiveness).

      I know the “cool” factor is present, but that’s just ego-based. You know what I think is cool? When perimeter weighting saves a bad swing, giving me something nearly pin-high and slightly off the green so I can still scramble for par, instead of squishy and short (usually in a bunker) where I’m likely to make a double. THAT’S cool.

      Play the clubs that work for you. All you have to do is see the number of Tour players slinging perimeter-weighted irons. THEY know.


      Boy do I agree with you, especially the part you said about how it is cool to catch one off center, see the ball get on the green and know that you just “stole one” from the course ! In “Tom’s perfect golf world”, muscleback blades would be banned because there is not one thing that they do which could not be duplicated in a higher MOI head design. Now I am glad my posts here don’t get seen by many because I am sure that statement of mine could draw some severe ire from those who insist there is a difference with a blade.

  35. Tom,

    Can you shed a little insight into your stepless steel shafts that are standard with the Sterling Irons? How would they play in comparison to other steel shafts such as Dynamic Gold, KBS Tour, Project X, etc? I have played an S2 Black in a driver and really was impressed but have not tired your steel offerings.

    • MIKE
      Yes, happy to do so. Our Stepless steel iron shaft is a better player shaft designed with a firm tip section for later release players. The feel of the shaft is similar to that of the Dynamic Gold or the KBS Tour, but not quite as tip stiff as are the Project X iron shafts.

    • Thanks Tom. Sounds like the S2 stepless would be a good fit for my game. I’m just having a hard time coming to grips with the fact that I normally play all my irons +1/2 inch and would be dropping down to 37 inches with all of the Sterling.

    • MIKE

      It only takes getting used to it mentally because for sure, when you address the ball with a 5 and 6 iron that is 37 or 36.5″ in length, at first it seems like you are using a Jr club ! But 4-5 shots to see ball flight and performance and it becomes something that changes from thinking of it as Jr length to being clubs that are really quite fun to hit and play with, if I do say so myself. Because of the ease of hitting a shorter length, with the low loft clubs it sort of starts to feel like you’re cheating in some way, is one way to put it !


  36. please make a left handed option! i would pre order if needed

    • We’re thinking long and hard about it right now, we really are.

      Thanks for your interest,

  37. Love the game of golf.. I have read a few of Tom’s books and have enjoyed them. The game has frustrated me over the last 6 years as my business has been blessed and my game cursed with lack of time to play. The fun has diminished…. I want to be competitive but children and work ( I own a funeral home) have taken my time. After trying the 1 iron golf clubs my friend had, I was fascinated with single length irons yet not impressed with his. I saw where Tom came out with the Sterlings…. Love Mark Crossfield… And went straight to his reviews…. I was hooked. From Toms website I called and met Rick at RMH Golf in PA… What an awesome, nice man…. He fit me and I ordered them. A few rounds later I have NO loss in distance, accuracy improved tremendously … Tom you have made golf simple and fun again for an amateur like myself. Thank you. Rick will next build me the appropriate driver and hybrid to suit my game. He is as nice as he is knowledgeable…. I literally have owned over a dozen sets of irons in less than two years (eBay junkie) and have realized the importance of quality control, and fitting. Tom Wishon and Rick…. God bless you and your dedication to the game and helping a man who loves the game… I feel like a tour player with quality attention to my game.

    • PAUL:
      How nice is that for us to be able to listen to your experience in being fit by Rick and having the results you have with the new Sterling irons ! Lots of people think that the most fun I get in my “work” is the process of conception and creation of a new design. They’re wrong – it’s being able to hear a story like yours and to see the smile on your face in between the lines of your message from being able to enjoy this great game a little more !!

      THANK YOU for sharing this, and thanks so much for choosing to work with a very good clubfitter like Rick.

  38. Hi Tom,

    Do you know any clubfitters in the Netherlands where I can get a set?


    • DAVID

      yes, for sure. I don;t know exactly where in the Netherlands you live so I am not sure how far these clubmakers would be from you. If neither one is close enough to be convenient, let us know with a response email to and tell us what town/city you live in. We’ll check more specifically to see if there is someone closer to your location. However, these two men are in my opinion the best clubfitters in all of the Netherlands so I shall hope one of them is close enough to you.

  39. Can my wife be fit for Sterling irons? The single length should help her tremendously. Charlotte area – Curtis @ Leatherman golf?


  40. Hello tom my name is Britton Munoz and I am a legally blind golfer. I purchased the sterling Single length clubs several months ago and was fitted by Paul Coon’s out of Redmond Oregon. The consistency of the single link clubs has improve my game drastically consistency is very important to me being your visually impaired golfer. Prior to the Sterlings on 18 hole golf course here in Oregon I would shoot a 105 to 110 now that I have the Sterlings and have the same swing with every club I am shooting under 100 the last four times out I shot A 96, 97, 96, and a 99. Today I shot a 44 on a par 35 so the consistency of your clubs are working and it is a great product anybody who is ever doubted going to the single- link clubs should not hesitate the consistency really works these are great product


      What a WONDERFUL, FANTASTIC message this is for me to receive !!!!!! I can’t tell you how nice this is to know that with the real challenge you face in your life that you choose to work hard to play this great game and that the Sterling irons are helping you to play a little better and enjoy this game a little more ! WOW ! Most people think that the most fun I have in my career is when I get to think up and design the new club models. They are wrong. The most fun I have in doing what I do is to have the chance to hear about your experience in having been fit into one of my models and to know that you’re having more fun yourself !!

      Thanks SO VERY MUCH Britton for taking the time to share your experience with us! The VERY best to you in this great game !!


  41. I am interested in a single length golf system. I am a 81 year old senior in pretty good shape approaching the low side of a senior swing speed. I am also in my 3rd year of trying to perfect the Mike Austin swing so am familiar with Jaacob Bowden’s work with Mike Austin and his videos. Especially the one on discussing the 1iron system. I believe I would require a hybrid iron type set. One other manufacturer recommended a 38 inch (?)length for a WTF measurement of 35 inches – maybe because of the hybrid nature of the clubs. I do feel comfortable hitting the longer clubs these days. The video was very interesting especially how you try to compensate in head design between the low end and high end irons. I assume all the heads are of the same weight. Will you be developing a set of hybrid irons ?

    • TONY

      I had an all hybrid #2 through PW set of hybrids in 2007 but not enough people wanted it. So we had to drop the 7 through PW hybrids from the set and we just offered it then as hybrids to be bought as long iron replacement clubs. It was a nice set, it played very well. But perhaps it was too far ahead of its time, or more likely, because none of the giant companies whose followers think the sun rises and sets in their back sides had such a set, our design set had no “credibility”.


    • Hi Tom,

      Is it possible to buy just a set of heads so that I can be properly fitted locally? I am in Thailand and cannot fnd a supplier here.



    • RAY

      There is a man in the Pattaya area who has been a custom clubmaker for a long time. Neil Cameron is his name. I would suggest you try to contact him. The phone number we have for him is 0890 769 623 and his email is if that doesn’t work out for you, let me know at and we will try to help you in another way.

      Thanks much,

  42. Hi Tom, I’m a club maker in Adelaide, Australia and on researching, have become interested in the single iron length set especially to newcomers to golf.

    I like the TT XP 95 S300 shaft, ultralight but also gives very good distance, maybe a very good match for your Sterling irons.

    Assuming each Sterling head is 274 gm, at 36.5″ in total club length, what shaft weight have you used to give the Sterling the desired swing weight.

    I’m a precise and particular club maker who hates having to add tip weights to obtain a swing weight, I feel if the iron heads are within tolerances and appropriate shaft weight and length are considered, the SW is just right.

    • Kenmar

      All of our clubhead models are made with a weight bore put right into the bottom of the shafting bore, below where the shaft tip stops in the hosel. This weight bore in every head is designed to accept weight plugs we make in 2g, 4g, 6g and 9g increments to allow clubmakers to achieve the final swingweight they desire in their custom assembly. of course, with the huge variety of different lengths, shaft weights and grip weights, no clubhead can achieve 100% of all possible final swingweights for all possible length shaft weight and grip weight ranges.

      But the weight bore we have put in all of our heads since day one of our company does work very well to help achieve most swingweight situations you would need to hit in your fitting. The weights are epoxied into the weight bore during the shaft installation procedure. If you need to remove them later on, the 2g and 4g are brass so they can be drilled out easily. The 6g and 9g are tungsten so they cannot be drilled out but they are made with a scredriver slot on the top so you could heat the lower hosel area, then twist the weights free to remove them.

      In our fitting with the Sterling heads, we have built with graphite shafts from 55g up to steel shafts of 115-120g.

      Thanks for your interest. If you wish to set up an account with our company, go to the top of the home page at and click on the link for ACCOUNT APPLICATION. Complete the information there, click to send it to us, and a staff member will contact you with all the information you’ll need.


    • Tom

      Was the 2007 hybrid set all single length?

      Does the 38 inch length recommended for a 35 inch WTF measurement for a hybrid set appear readonable ?

      I know ithat’s about the length of a standard 5 iron and the length of my current Callaway 6 Razr HL hybrid which I seem to hit OK.

    • TONY
      No, it was designed to be made to incremental half inch lengths as per a normal iron set. 38″ for such a set seems reasonable ONLY IF IT GIVES YOU MORE COMFORT over the ball for your back situation. Single length irons of any head design at 38″ is a very bad thing in terms of trying to expect any level of control or accuracy or distance control with the #8, 9, PW, GW. but if your back feels much better at that length, then that rules the roost and you will just have to figure out a way to get used to swinging such a long length for the high loft irons and wedges.


  43. do you sell custom sets or do you only sale the heads, shaft etc

    • MARCUS
      Sterling irons are available in two ways. 1) you can work with an independent custom clubmaker to be fit for a set. You can search to see if there is a certified custom clubmaker near to you by heading to Right in the middle of the home page you will see the FIND A CLUBFITTER Search Tool. Click on that, input your town/city and the clubmakers closest to you will pop up. Contact them to inquire of their pricing and services to set up a fitting appointment.

      2) if there are no clubmakers close enough to you, we have partnered with a golf professional to set up Through this site, you have two options for purchasing a set. One, you can input all your specs you want the irons to be made to have, if you do know your specs and are comfortable with them as being right for you and your swing. Two, you can answer a series of questions and we here at Wishon Golf will analyze your information to create the fitting specs to which the clubs will be made to fit you as well as possible. Pricing for the irons on can be seen by scrolling down to the set options and clicking on them to see the pricing.

      Thanks very much !

  44. I really like this concept but those of us whom are lefthanded get treated like stepchildren. How long will it take to give us the opportunity to buy these? Does 565’s come in left hand?

    • MARCUS

      I am very sorry about that. It truly is NOT a matter of treating left hand golfers as stepchildren at all. It is purely a business decision I am very sorry to say. Never once in over 350 different head designs over my 31 yr career as a club designer have I seen one left hand model that sold more than 8% of the units it did in the right hand version. This is purely a statistic from the fact that 6% of American golfers play left handed, 15% in Canada and 8% in Europe. So until the right hand version of a model shows that it is doing enough volume that 8% of that can cover the tooling die and inventory production expenses, we have to wait and see before we pull the trigger on left hand. I am sorry. It is just a hard fact of business in this industry and in no way is any form of discrimination.


    • Does 565’s come in left hand?

    • MArcus
      I’m not making you very happy these days I realize with my answers. For a smaller company like ours, I can at least offer a definite answer to say that it’s highly doubtful we will ever be able to offer any of our forged carbon steel iron models in left hand. The tooling die costs for forgings are over $60,000 for the full set – that’s 10 times the cost of investment cast tooling dies – so with the 8% statistic ruling this, it just will not be in the cards for us to offer a forged carbon steel iron in left hand.

      I’m very sorry,

  45. Hi Tom,

    I’m based in Bangkok. So getting fitted for your clubs would be difficult.Can it be done on line ????. Although I’m not sue of the accuracy of doing that.

    Your 5 Hybrid really interests me. .
    What advise on your shafts can you offer for me being a Senior with a club head speed of around 80 MPH. Do you offer Senior shafts ????.

    Would the 5 Hybrid work for me, leaving out the 6 and 7. And then going to the 8 through to SW. ???? Would that be a disadvantage ?????

    I would appreciate and guidance you can offer.

    Kind Rgds.


    • Daniel:

      There is a very experienced clubmaker in the Pattaya area by the name of Neil Cameron. I’ve known him through technical correspondence for quite a number of years in which he’ll ask questions about golf equipment technical matters and I answer and we discuss it. So I know he knows what he is doing. I am not completely sure how much work he is doing these days. But you can call him and talk to him, tell him what you’re interested in, and find out if he can help you. his phone number that we have is 0890 769 623 and his email is .

      If that doesn’t work, then the fitting side of the offerings through is not too bad because we here at Wishon Golf are doing the analysis of the answers to the fitting questions to compile the spec recommendations for the clubs.

      Thanks much,

  46. Hi Tom,

    Can you tell me where I can be fitted for a set of your single length irons in Thailand?


    • RAY
      Thanks very much for the interest. Two suggestions we can offer to help. First, I have known Neil Cameron in Pattaya for many years in the clubmaking business so I know he is a good clubmaker. You can contact him to see if he can help you – phone is 0890 769 623 or email at If for some reason that doesn’t work out, we are working in concert with a golf professional to support his direct sales website for the irons which you can find at There you can either choose your specs for the irons if you know what you want exactly or you can answer a series of questions from which we here at Wishon Golf will form the custom build specs for the clubs. can do international shipments for the irons.

      Thanks very much !

  47. Hi Tom, thanks for producing the video. I have been interested in single length clubs for some time now but I’ve had trouble convincing local club makers of my perceived benefits. My question is – can’t I just shorten and lengthen the irons that I have – ok the weights and centres may be slightly different but changing present club shaft lengths will take care of the main features of setup, stance, ball position and swing consistency. I suspect that most amateur golfers like myself will never attain consistent gapping with varying length clubs anyway due to the inconsistency of strikes, particularly with long irons, – so long as the gapping is reasonable then it’s certainly more important to hit consistent distances rather than be gapped for exactly X yards on perfect shots. I also suspect that the distance the ball travels is more a factor of the loft than the shaft length – can the loft not just be tweeked accordingly? I think that most amateurs also try (or maybe it;s just me!) to swing faster with long irons but when I’ve intentionally swung the same way with my 6i and 8i the measured club head speeds were only separated by 1 mph! Thanks. Brendan.

    • Brendan
      It’s much more than a little bit of work to try to convert any existing set of irons made for conventional incremental lengths into a single length set. In Sterling, because we are keying this to an 8 iron length, every head is designed to be 274 grams in weight and 63* lie angle. In every conventional set, the head weights start at around 239g with the 3 iron, then go up by 7g per head to a weight of around 283g or so for the gap wedge. Lie angles typically start at around 58* on the 3 iron in a normal set and progress up by 1* increments through to 64* on the 9, PW, GW. Most sand wedges being standalone wedge models have a head weight of 300g and a lie of 64*.

      So depending on the length you choose for the single length set, you will have to add a HUGE amount of weight to some heads and remove a fair bit of weight from higher number heads. Not to mention bending the lies. If your set is stainless cast, 2* of lie change is about all that most cast stainless sets can allow because of the low ductility of the typical stainless alloys used to make cast irons.

      You can envision adding gobs and gobs of lead tape to a head to increase its weight. Might look lousy but it could technically be done. Where you’d have the real problem would be removing weight from the higher number heads. That’s no small task to do and not damage the sole or performance of the head. So in the end, more people who have tried this have found it to be a nightmare to try to do.

      You have no more difficulty achieving proper distances and distance gaps with our Sterling single length set than with any other iron set. Really that is a fact. yes, you probably will hit each Sterling iron a little different distance than you hit the same number irons in your normal set. that’s to be expected because of Sterling’s single length with each head’s loft and the high COR face of our #5, 6, 7 heads. But we find so far from a lot of comments from those who have the irons that most say they hit ALL the irons longer than they hit the same number irons in their conventional set, down to where the GW is pertty darn close to the same distance as their conventional gap wedge.

      Hope this helps,


  48. Hi Tom,

    Ordered the full set of heads. Any news on when they will arrive?? Real anxious to get these in my hands. Playing the Pinhawk at the moment since that was pretty much all that was available and they perform well. I’ve gained some distance in the short irons which is to be expected but have not lost any in the longer irons. Can still get 200 from my 4 iron but the trajectory is lower. Your design will perform even better and that I’m anxious to see.

    Thanks Tom,


    • MIKE
      I am out of the office, out of town right now. I can’t answer your question about when the order will ship. Please call our company at 800-470-0072 and ask the staff member who answers your question. They’ll want to know the date you placed the order so they can check and give you an estimate for when it will ship. We are catching up slowly but surely on the orders.
      Thank you,

  49. I demoed then ordered a set through Howard Garson at Howard’s custom clubs in Fort Lauderdale last week. I was truly impressed by the trial. At one point I was hitting the ball so straight that on the monitor you could only see my shots starting not landing. After about five like that in a row I had to comment to Howard ” I’m actually not this good. “. But, I’m beginning to think maybe I will be. (Current handicap 8). Do you have any idea how long of a wait I may have for my clubs?

    • Mr. Evans

      Thanks very much for taking the time to comment and let us know how well you liked the irons in your trial. BTW, you’re in VERY good hands with Howard – I’ve known him for a while and I can tell you that he is VERY seriously into always advancing his knowledge and doing the best for golfers who work with him for their fitting needs. Howard corresponds a lot with me on technical topics related to fitting and equipment performance so I can tell his level of knowledge is very good.

      It’s very difficult to know which of Howard’s orders for Sterling iron heads might be for the set for you. But I can tell you that Howard has an order in with us for 2 sets of the heads that at this point is scheduled to be filled from the shipment of heads we get from our production factory next Tues or Wed. So it’s possible these could go out before the end of next week to be on the way to FL.

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

  50. Hi Tom,

    I have read about the Zero Shifting Motion in Homer Kelly’s book, “The Golfing Machine.”
    And I would like to my stance to be as upright as possible and still have an effective swing.
    I wanted to know what is the maximum bend of the lie angle that the Sterling heads are able to withstand. From your description, it looks like 63 is the lie and can be bent 4 degrees in either direction. Would a 69 or 70 degree lie angle be too much stress for the Sterling heads?

    Thank you,

    • CRAIG

      Yes, that’s too much of a bend. because of the high strength steel alloy face in the #5, 6, 7 irons, the heat treatment we have to do to get the faces up to their required strength for their thin-ness to hit the high COR, that heat treatment has to be done with the face plates are welded to the carbon steel body of the heads. The heat treatment then has the effect of also stiffening up the carbon steel of the 5, 6, 7 irons. So doing a +4* bend would definitely be the absolute limit for bending. You could bend the 8 to SW more than that because they do NOT have the high strength steel high COR face as do the 5, 6, 7 irons. but it would not be any good to have some irons more upright than others, so the limit is +4* at the most for the bends.


  51. Excellent. Thanks, Tom. I think I was reacting to the old notion (a la the EQL) of a set centered on the 6-iron length. I just couldn’t imagine hitting a PW at that length, even with the benefits of standardization you’ve described. But the difference between an 8 and a PW is only an inch. Heck, you see those differences between traditional sets, like TM juicing their clubs with longer shafts and stronger lofts. A PW from that setup already plays like a 9 and (sometimes) feels like an 8.

    Being able to hit the lower numbers in a setup like this is a big deal. Most golfers aren’t strong enough (don’t have enough swing speed) to maintain the gaps. This is true of traditional sets, too, but they’re assisted by the longer shafts and weaker lofts (compared to a set like Sterling, which seems to have stronger-than-usual lofts in the “long” irons to compensate for the shorter shafts).

    Okay, I’m officially over my head. Thank you so much for your continuing innovation. The nearest fitter to me is 40 miles (Fredrick, MD–I live in Northern Virginia), but I think I have to go and check these out.


    • RICH
      thanks for your understanding. I’m pleased to hear you picked up on the way the shorter single length could allow players to get more used to the high numbered irons vs the usual 6 iron length. This need to have the high number irons under more control was the main reason we chose the 8 iron length for the single length. Others can’t do this because that short of a length would definitely bring about a loss of distance with the lower loft irons now being too much shorter than in a conventional set. But this is where our experience with high COR face engineering comes to the rescue so we can do the 8 iron length and make it work all through the set.

      If the clubmaker in Fredrick is Mike Bednarcik, you will be in very good hands. I know Mike and I know he has very good knowledge and experience in fitting. One thing though – do for sure call before you go because not all the clubmakers have demos or inventory in the Sterling heads. We got slammed with pre book orders that continued to built up over Feb and March before the shipments of the heads began to arrive. so we are slowly catching things up, but many of the clubmakers won’t have their demos until mid to even late May. Hence the reason to call to see when Mike feels he may have demos on hand. Not sure where you are in No. Va. but if you’re not too far from Richmond, in the suburb of Glen Allen is Charlie Sampson who is also a fabulously experienced fitter you could work with. I think Charlie jumped on the Sterling order bandwagon very early so he may have his demos now. If you go to the FIND A CLUBFITTER search tool on our website and put in Richmond, VA, you can see his contact info at the top of the listings.

      Hope this helps,


  52. Great stuff, Tom. I’m confident you’ve overcome the engineering challenges that failed in the Tommy Armour EQL and other, similar efforts. But I have two questions. First, was making a 4-iron just too big a stretch given the length (36.5″) you chose to center these on?

    Second, wouldn’t it make more sense to equalize the long irons, but allow the short irons and wedges to progress naturally (get shorter as they do in traditional iron sets)? After all, the two reasons long irons are hard to hit are (a) their length and (b) their loft. But in short irons and wedges, both of these are easier. I’m thinking 4-9I at the same length, with the wedges progressively shorter.

    As it stands now, it seems the lower numbers would be easier to hit, but the higher numbers and wedges would be harder, with some of this tempered by the potential consistency of hitting an entire set at one length.

    • RICH:
      Yes, the 4 iron would require too high of a clubhead speed at 36.5″ to be effective. I did tool a #4 prototype in a hybrid head and it just was too tough for avg players to get the ball up well enough to fly its full distance at 36.5″ length. it took a >85mph speed at 36.5″ to do that and that’s a speed that most people do not have for that length.

      If you make the high number irons and wedges to be of a different length than the rest of the irons, you destroy one of the main benefits of a single length set. You eliminate the fact that ALL of the clubs would have precisely the same swing feel. You can’t get around that. One of the two main reasons that single length is even worth talking about is because single length means every single possible element that has any contribution to swing feel is identical in each club. Same length means same shaft weight, same exact shaft bending (flex), same exact total weight, same swingweight, same MOI, same balance point. There is NOTHING ELSE that affects swing feel. Add to that the fact that same length and same lie means same set up position, same posture, same spine angle, same swing plane. Different length irons doesn’t allow that.

      If you change to a shorter length in the 9, P, G, S clubs from the others in the set, you break this so those clubs in the set do not all have the same everything, with perfect identical swing feel.

      The origin of your question about this was a BIG reason why we chose an 8 iron length as opposed to the previous usual 6 iron length everyone else seemed to want to use or still does want to use in the other companies’ single length sets. At 36.5″, you are only 1/2″ to 1″ longer than what the “normal” length for the 9, P, G, S in conventional sets. That’s not very much more length so the chances of that little bit of additional length having the effect of screwing up distance or accuracy is far less than if you try to play the 9, P, G and S at 37.5″, a 6 iron length.

      Besides, we already had good proof that an additional half inch or inch in the 9 to wedges is insignificant. For years we have suggested clubmakers adopt a 3/8″ increment of length change in a conventional iron set between irons as a way to, 1) help do MOI matching of irons if they wanted to do that, 2) to give golfers a little more comfort over the ball with the 9 to wedges – with 3/8″ increments vs 1/2″, you slightly gain length with each iron so that by the time you get to the 9 to wedges, you are now in the realm of 1/2″ to 1″ longer than you would have been with those irons in a normal half inch increment set. There are a lot of golfers who feel they have to bend over more or crouch down more with their 9 to wedges in a normal half inch increment set. So 3/8″ increments has become popular with some clubmakers for its ability to bring about more comfort over the ball with the higher number irons and wedges. And in doing this, no one has complained about too much distance or lack of control with 3/8″ increments causing the 9 to wedges to be a chunk longer than they were.

      There is a lot to be said about the fact that golfers haven’t discovered when you have a set of irons in which every iron does have the same precise swing feel – and I am talking about the effect OVER TIME of playing a set in which every iron is identical in swing feel. Over time, after days and days of hitting shots, the swing begins to get more used to every club being identical so the swing becomes more repeatable, more consistent, and from it shot consistency does the same. So this too is how the high number irons fall into place for more consistency.


  53. Tom: Thanks for the reply and info. I see there is a club fitter up in Melboure, FL., Ray’s Clubfitter. I think I will contact him to see if he has any of your clubs that I can hit on his range to try out. I have a pretty low swing speed (hit my Adams 3h about 140-150 yds) so not sure if they can do anything for me, but figure I should give them a try.


  54. Mr. Wishon: Very interested in your new club design. I have been looking through all the info you have on the Sterling clubs but can not find what lofts the clubs are from the #5 to the SW. Could you please tell me the lofts or point me to the proper place on your website with the loft specs? The club I hit the best in my bag is a Adams 6H which I cut down to 38.25 inches. It has a SW of C0. I play in the low 90s most of the time and have the most trouble hitting my higher lofted irons #7-9 consistently. I think what bothers me the most with the higher lofted clubs are the more upright lies. I am pretty consistent with my 3H to 5H and feel I could get in the 80s more often if I could find some higher lofted clubs that I could hit better. Thanks for your time.

    • Jerry there is the direct link to see everything about the new Sterling single length irons. The reason we set lofts a little lower is because we’re ordaining the single length at a 36.5″ 8-iron length. This is shorter than any other previous single length models so we can offer golfers a higher incidence of on center hits and ease of play, but then not to lose any distance due to the shorter 8 iron length. Coupled with this is the other engineering feature to prevent distance loss no other single length model has, which is our proprietary high COR face design for the #5, 6, 7 irons in the set. Early reports coming in now from first users of the Sterling irons say the golfer actually hit the ball longer than they do with their previous irons and have zero issues with distance or trajectory with the lower loft irons. All the heads in the set are made from soft carbon steel so whatever lie angle fitting needs a golfer has can be easily achieved.
      Thnks much for your interest – if you need help in finding a clunfitter to work with, let us know at and we will be glad to help.

  55. Tom,
    I have a player who wants to go with the Sterlings. He is a high-swing-speed player. He would normally include a 4 iron in his set-up. What do you think about using two 5 irons and bending one 4 degrees strong? If not, what would you suggest?


    • Dennis
      I’d start him with the 5 iron and see how far and high he hits this club at the single length you and he will choose, either 37″, 36.5″ or in between. I’m going to bet that with this high COR face and 23* loft on the Sterling 5-iron that he may very well hit that club as far as he hits his current 4 iron, so this 5 would become the 4 in his set, distance wise. In truth, and maybe this will happen down the road, in the single length concept there should be different head designs for different clubhead speed players. But we could only throw the dice this year with one set design in single length. So it had to be of a head design concept that could work for the greatest number of players, which means the players who shoot 80 to 100.

      In my mind when I think about the really good player or the very high clubhead speed player, I would design a little different set of heads with different lofts. Much higher speeds can get enough ball speed and spin to push a 36.5″-37″ length normal COR iron with 20* loft high enough to fly and carry well. 80mph or lower for the 5 iron speed can’t.

      Not to say the Sterling can’t work for the better player. it’s just that you will have to ask the player to hit the 5 iron, 7 iron and 9 iron several times on the course to get a feel for the distances so he knows what club to pick for what distance, and also to know where his 5 iron distance is with respect to his old 4 iron and where his hybrids and woods need to be set up in the whole set.

  56. I live in Toronto, Canada, do you have any fitters in this area and if not can a standard set be ordered and just adjusted as need be at my golf club?


  57. Love the addition of the explanatory video as validation of the concept. Jim Battin has or will place my pre order. I can’t wait for them to come in. Glad to hear your position on individualizing the shafts as the other one iron producers insist on their own shafts. I am 69,9Hdcp and have played with Nunchuk shafts from driver to 62 degree wedge since they became available. Because of the consistency they have provided in uniform swing and feel regardless of iron and the single plane (Moe Norman) swing I went to four years ago, the logical next step was to the single iron set. Because of increasing arthritis and tendonitis that has come with aging, Jim introduced me to the Enlow oversized reverse tapered grips that has been a great compliment to my shafts and swing and allowed me to release the club better without the usual pains I had been experiencing. At the end of last year we worked together to “fudge” my set of clubs as best we could to single length(36.5) and lie (63) plus a lot of tape on my part to get my set as close as possible to similar swing weight but exact balance point with dramatic improvement in shot consistency and accuracy. So, the prospect of starting this season with your clubs specifically designed is beyond exciting. I am extremely grateful to Jim for turning me on to you and your company. I play competitively on both the Golf Channel and Golf Week Senior Am Tours, Columbus Chapter, and undoubtedly will be the only Sterling Iron player. Looking forward to an outstanding tour year.

    • Thanks very much Rick, for your interest and for sharing your experience in fitting with Jim’s help. It’s great that you have found the benefits of working with a good, experienced clubfitter/clubmaker like Jim. Maybe someday a whole lot of other golfers can discover this too and quit relying on the big box stores for their equipment needs and help. Best wishes to you in your continued play and enjoyment of this great game !


  58. Once I have found the correct length for a customer, do I then fit as I do for standard length clubs with frequency, spine puring, moi, ect.

    • PAUL:
      With the Sterling, your length determination is simple – you have a choice between 37 and 36.5″ or in between if you care to. That’s determined by either the golfer being more comfortable with one over the other, really more than anything technical. Players with a greater wrist to floor may opt for 37 and everyone else at 36.5. Then it is a matter of really focusing on fitting for the right shaft weight, total weight, swingweight/headweight feel – this is the most important part of single length fitting to get the weighting right because that keys into really making the single length result in the highest level of swing tempo consistency, on center hit consistency for the golfer. Blow the weighting of the club and you definitely reduce the chance of single length doing what it is designed to do in terms of improving shot consistency and on center hits. Then you have to definitely do a dynamic lie test to get the right final lie on the clubs. And for some players, you may have to let them play the set for a month, then come back to you if they have any distance gap issues that you may need to bend/tweak a loft here or there to fine tune.

      By having made them all to the same length, same shaft weight, same total weight, same swingweight/headweight, you will have automatically made them to have the same MOI. So no additional MOI match work need be done. Frequency matching of all the shafts or spine/PUREing is optional. In all honesty, when you are talking about 8 iron or 7 iron shaft length in an iron, the shaft is not going to be bending very much at all during the swing because iron shafts to begin with bend half as much as do wood shafts. and within iron sets the shorter length shafts like 7, 8, 9, PW hardly bend at all for most players. Hence things like freq matching or PUREing/spineing really are not going to add much at all. Not like they can in woods or in longer iron lengths. But if you want to do those things to add value to the set and the fitting, go ahead and do so but make sure you market the fact you are doing this to the golfers so they feel even better about the depth and quality of the care and work you put into the clubs for them. In the end, you will influence performance far more from really nailing down the right shaft weight, total weight, swingweight/headweight feel and lie fitting for the golfer than from freq or spine work.

    • Thanks Tom, appreciate the info

  59. Do they come Left Handed ?

    • Sorry Lonny, not yet. As with every model we create, we really have to see if the model can be popular enough in RH before we can pull the trigger on tooling die and inventory investment to offer it in LH. This is because never in my 31 yrs of design have I ever seen a LH model get more than 8% of the unit sales it does in the RH version. So in essence and stated somewhat coldly I am sorry, we have to wait and see if the RH demand makes the 8% payback work. Maybe, because so far the interest at least in terms of the number of inquiries about Sterling has been pretty strong. So we’ll see how that works out.

  60. Tom:

    The Sterling Single Length concept is something I have been interested in for quite some time. I have customers that really want to pursue single length as well. My one question is this: If I choose the 36.5″ Length for the 5 Hybrid thru PW would this also mean I would have to adjust my Driver and 5-Wood length as well? My current Driver is 43.75″ and my 5-Wood Wishon of course) is 42″.

    • JIM:

      Driver and wood length HAVE NO RELATIONSHIP WHATSOEVER TO IRON LENGTH. We fit driver and wood length purely on the basis of the golfer’s ability and swing characteristics. As such, that means the smoother the tempo, the more square to inside out the swing path, the later the release, the better the golfer’s ability, the longer the driver and wood length COULD be – not SHOULD be, but COULD be. hence in the other direction, the faster and more forceful the tempo, the more over the top outside in the path, the earlier the release and the less skilled the player, the SHORTER the driver and wood length MUST BE to offer the golfer the best chance at keeping the ball more in play.

      Iron length is purely about COMFORT – to make sure the golfer is comfortable over the ball for his particular stance and posture. Iron length fitting has nothing to do with the golfer’s ability, and is only about comfort. So if you use single length with a player for his irons. you go about fitting the driver and woods separately based on what I mentioned and you do not even consider the length of the irons as any factor whatsoever in the driver and wood length fitting.

      Hope this helps, thanks so much for asking the question because this is VERY important,

  61. Tom, what shafts are available for the Sterling heads?

    • Marcel:

      They can be fit to the golfer with ANY IRON SHAFT that fits the golfer’s swing speed, transition, tempo, release, strength and his sense of feel. of course we did the bores at 0.370 so it sure would be easier to pick a parallel tip iron shaft than to try to shim in a taper tip shaft. But there is no such thing as a special shaft to go with this single length concept. Use whatever iron shaft best fits the golfer. And of course we have a great offering with our S2S shaft designs – 5 different graphite iron shafts in many flexes from 55g to 115g, and two steel shafts in R or S of 100g and 115g.


  62. Do these heads include a hosel port ?

    • Yes Al, they all have the one hosel weight bore at the bottom of the shafting bore.
