SINGLE LENGTH IRONS
Wishon’s new single length iron design concept EQ1-NX offers same length and high COR low loft iron characteristics while adding many new performance enhancing features to mark a definite step forward in game improvement iron design.
Features:
-
- Enabled by the new 2-piece hollow body design, the Center of Gravity moves progressively through the set from lowest and most rear located on the #5 iron to highest and most forward located on the GW and SW to achieve more consistent shot shape and shot height for each iron in the set
- The hollow body design throughout the set increases the MOI of each head by removing all mass from the inside of the head to be distributed all around the CG. The hollow body construction also enables the CG progression and uniform impact sound between the high COR and conventional COR heads in the set
- Low number irons are better matched with their loft to CG position to achieve preferred shot shape/height and allow a wider range of players to be able to effectively hit the #5 and 6 irons to fly and carry with proper distance gaps
- Traditional GW and SW profile shapes are combined with milled faces and a custom sole grind make the wedges a great choice even if they were standalone wedges and not part of the single length design
- 275g head weight with hosel weight bore allows assembly to any single length between 35.5” and 37.5” while still being able to achieve a reasonable range of swingweight/MOI (depending on shaft weight and grip weight)
- Available in RH in #5-9, PW, GW, SW, LW. Available in LH in #5-9, PW, GW, SW,

Tom,
My question is about the history of shaft length for incremental clubs (variable-length clubs)
I cannot find any information on this.
I will appreciate it if you can help
Johan THat’s a very good question and one that I do not have the absolute, clear answer to. I can tell you a few things from my many years of researching old golf clubs but I don’t have the definitive answer. From the time the game started in the late 1400s until the early 1900s, golf clubs were only made and built by individual craftsmen, relying on local sources for the materials and means to actually make the clubheads and shafts and grips. There were no golf companies per se until the very late 1800s to early 1900s. A community… Read more »
Tom,
Thanks for your response, it certainly is really useful. I find your statement ” So the first “standards” for club length were simply determined from what the clubmaker remembered were the most common lengths by average that he had built for numerous golfers over the years.” very interesting. So the variable lengths were based on the single-length custom-fitted for players of different sizes.
Thank you once again.
Kind Regards
Johan
Johan Most of the specifications for golf clubs were established first by trial and error by clubmakers who made hundreds of sets of clubs and just remembered how they made them for the different golfers. Then when a new customer came to the clubmaker, the clubmaker would note his size, strength, ability, and refer back to clubs he’d made in the past for a golfer who was close to the same in these areas. Over time, that’s how most of the club specs evolved. One of the fascinating ones was the FLEX of a shaft. Making the shafts to different… Read more »
Hey Tom, question about distance dispersion.
I’ve been playing EQ1-NX irons and hybrids for a couple seasons, love them. This year, my ball striking has made drastic improvements, and as I’ve gotten much more accurate left/right, I’m noticing more than the occasional “hot one” that flies an extra 10-15 yards.
I’m curious if this has to do with the hollow body design, and if so, would I benefit from switching to a more traditional 1-piece forged club?
Matt There can be a few reasons for an occasional “hot one” but it is true that in any iron that is made with a less than thick face, meaning both high COR face irons as well as hollow irons with conventional steel material for the faces, it can be possible for conditions of the path and angle of attack and point of impact to result in the face being flexed inward a little more. And that in turn can increase the ball speed, which increases the distance for that shot. ALso factoring in this is the golfer’s clubhead speed.… Read more »
In addition to Tom’s more technical answer: As golfers learn the game and improve, their chances of making a great swing with great contact on occasion go up, so much you start noticing it when it happens. But this siren can be a temptress, making us think we can do that more often. (This is why they put more bunkers in the front of greens). It helps to remember that, as Bob Rotella reminded us, Golf is Not a Game of Perfect. But it is a game of “good.” David Owen, in his wonderfully anecdotal My Usual Game, tells the… Read more »
Hi Tom,
I’m going to order some SL EQ1 NX, just wondering about shaft recommendations. What is a good fit for the heads for someone coming from T100s with project x iO stiff? My 7 iron is about 165 with around 98-103 driver speed. I’m also curious what you think about the nunchuck iron shafts, I had them suggested. Thanks for any help!
JAMES You’ll always find me to be one who says if you are going to contemplate a change as significant as from incremental length irons to single length, why double up the change by changing the shafts? Especially when you say you have been playing a shaft that you seem to like and which seems from what you say to feel and perform well for your swing. So if you are just looking to “dip toes in the water” with a contemplated move to single length, I would say get a 6 iron and a PW and shaft them both… Read more »
Hello, I have the original sterling single length irons and I have also owned the original Cobras and Edel SLS-01 clubs. I like the original sterling’s since they are more forgiving than the Edel’s and less “clunky” feeling than the Cobras. However, I really like my 4 iron in both the cobra and edel irons. I would like to try the EQ1-NX heads. Can a 5 iron be bent up to 4 degrees to have a comparable 4 iron loft at 21 degrees. I’m swinging these clubs between 90-95mph at 37.5inches and have not had a problem getting the height,… Read more »
Nick I also would ask, wasn’t the original CObra and Edel 4 irons made to be longer than the rest of the single length irons, as a way to help give the golfer a few more MPH of clubhead speed with the low loft irons to help them get up and carry more than they would had it been made to the same length as the other single length irons? I can’t remember that for sure, but I sure seem to have a sense that was what Cobra at least did. Not sure about Edel. If the 4 iron was… Read more »
Hi Tom – Are you working on a new set of same-length clubs – thinking of buying the EQ1-NX but would wait if you’re coming out with a new model soon?
JAY If you had followed Wishon Golf over a period of time you would see that we are so totally unlike the big companies in several ways. One of the primary differences is that when I design a new model that passes muster to be added to the product line, it generally stays in the product line for quite a few years. For example, the 919THI driver has been in the line for over 12 yrs, the 771CSI irons for almost that long, and so forth. The reason is because in our business model, it is all about CUSTOM FITTING… Read more »
Great answer! Thank you Tom for taking the time to respond.
Do you recommend the 60° lob wedge for a high handicapper?
Thank you for your time.
MARC No, I don’t recommend a 60* wedge for a high handicapper. The only times that I recommend a 60* wedge are, 1) if the player has always demonstrated extremely good control of the hands through the ball with his short game shots – meaning never hitting fat, thin, skulled shots and his impacts are almost always solid; 2) if the golf course has lots of raised greens, small greens with undulations and small areas for pin placements, bunkers with steep/high walls, AND the player has decent control with his hands through impact. Once you learn the proper swing motion,… Read more »
Not a high handicapper (single-digit) here and I still don’t recommend the 60-degree wedge, but for an additional reason to the ones Tom gave. Take another look at Tom’s comments. Everything in there is about how the 60-degree wedge is less useful. He’s right. It’s a highly specialized club, one you will not use frequently. Yet, it takes up one slot of the 14 clubs you can carry in a round. You might find more (and better) use with an additional wood or hybrid instead. A big mistake is using it for distance control. Because of the high loft, it… Read more »
Thank you for your answer and for the south of France, you have a recommendation please ?
Fred
I recommend you contact Andre at Golf’n Swing because during the Covid years, he developed a remote/virtual procedure for being able to fit people who are not able to come to his workshop studio. I know that with Andre’s experience and knowledge that he was very successful in doing this and the golfers he worked with this way, were quite pleased with the results. That would be my best recommendation since I do not have a good fitting recommendation to offer you in the south of France.
TOM
Bonjour Fred,
J’ai été formé par Arnaud Maurin,
Mon nouvel atelier ouvre prochainement à Mallemort (13)
N’hésitez pas à me contacter.

Hello
Where can we find your EQ-1 in France please ? Do you know a clubmakers ? Thanks for your work !
FRED
If you are near Paris, we recommend you work with clubmaker Andre Thaon at his Golf’n Swing business, in LePecq, a suburb of Paris. His contact email is golfnswing@gmail.com, the phone is 33 139 161 860, and you can find out more at the website – golfnswing.com. If you are closer the west of France, you can work with clubmaker Arnaud Floirac – arnaud@33golflab.com, phone is 663764809 and the website is 33golflab.com. I hope this helps and thanks very much for your interest,

Will Wishon be releasing new single length irons? Maybe a 3-4 utility iron?
RUSS WE have no plans to create a new single length set of irons anytime in the near future. The EQ1-NX model was introduced in 2019 and it has proven to be everything that I wanted to create in a single length iron design. Our company has a long history of being able to keep models in the product line for a lot longer time than the big heavily marketed companies because our designs perform very well and from that are able to keep their popularity longer. I will likely never design an actual iron head model for a single… Read more »
It’s been my experience that there aren’t many leaps in iron technology from year-to-year, despite the constant introduction of new models. (One might argue there have been few significant improvements in decades. Single-length irons have been an exception.) As for the 4-iron at an 8-iron length, I did that with the first-generation clubs (Sterling) in 2016. At the time my 8-iron swing speed was 88mph. I still couldn’t get good gapping (on carry distance). Instead, it became a driving iron for me (since the roll-out was good) until I finally pulled it from the bag for good. When I switched… Read more »
Rich About the only “advancement” in iron design over the past ten years has been the modern “re-introduction” of hollow body iron construction. I say re-introduction because I remember very clearly when I was working for Ralph Maltby in the early 80s, he designed a hollow iron which to my knowledge really was the first one done. I remember working the PGA show when we intro’d these and were showing them to the attendees, the reaction was HUH??? No one could grasp the potential of what that hollow body construction could do. Neither did Ralph, to be honest with you.… Read more »
I just rebuilt my EQ1 set after wearing out the first ones. The first set was with heads from just after the EQ1s were released. The new set is from heads I bought last year. S2S white in both cases. The new ones feel crisper than the old. Noticeably better impact sound/feel. Did the metallurgy improve or were the old ones just worn out? I don’t remember the old ones ever seeming so crisp.
Mitch Since 2021 the EQ1 clubheads have been made by a different factory than they were from their introduction to that point. I switched factories for the production mainly because the original factory got into a really bad position for delivery when Covid brought about a huge boost in playing golf and the demand for clubs exploded. The original factory got to a point where their lead times were a full year, something we just could not deal with. So I switched the production over to the same factory that has been making all of our more specialty clubhead designs… Read more »
Tom: When I switched to the EQ1-NX from your first model, I also went to a graphite shaft. My Wishon fitter in Tucson did a great job testing different shafts, and we selected the UST Mamiya Recoil 780 F4 (Stiff). It weighs 87g at 41″. We fit them at the standard 36.5″, but it’s the weight that matters here. When recently pondering the Autoflex shaft for my driver, I saw an interesting video on that shaft and how to easily simulate its performance with a much less-expensive shaft. The author of the video suggested going down two classes in stiffness… Read more »
RICH
You probably could do the same thing with a shaft for use in the irons But one thing I would add to that which might be difficult is to also have as low of a torque as possible with the more flexible shaft as a means to also cover up and hide the feeling of the shaft being that flexible.
TOM
Thanks, Tom. Great point on the torque. I’ve always been sensitive to it in my driver, but I might have missed it in this venture. And not just the feeling, but also the performance.
I appreciate it!
We’ll, I did it. I switched one club to try it out, staying with the same model, dropping two categories of flex and losing almost 20g. The torque is just slightly higher, so little I did notice. The result was about a half-club in distance increase with no change in feel. Except that it feels like the shaft is loading more, but that could just be me. I’ve just had the whole set done, and I’m looking forward to playing them if this Phoenix heatwave ever let’s up. I was still swinging the 8-iron at 85mph, so I never would… Read more »
what’s your swing weight? and the break down (weight of the club head, grip, shaft, and shaft length?
Hi Tom,
I’m currently using a set of EQ1-NX irons. I prefer the feel of irons opposed to hybrids, Is there a way to get a 3 & 4 iron to match the same profile as the rest of the EQ1-NX irons?
RONALD No there is no 3 or 4 iron with the EQ1 single length irons because we learned from the first generation single length design I did that only a very, very small percentage of golfers have the clubhead speed to be able to elevate the shot with a 4 iron, let alone a 3 iron, high enough with enough spin to enable it to achieve a full club longer carry distance than the 5 iron. Keep in mind that the EQ1 single length irons are most typically made all to be an 8 iron length. That’s 2 full inches… Read more »
Ronald: I’ve played the EQ1-NX since its introduction, having played the previous version for 4 years before that. Back then, I swung the 8-iron 88mph. After being thoroughly satisfied with my set, I added the 4-iron. But I just couldn’t make it work for the reason Tom describes. Just not enough to gap it properly from the 5-iron. When I did move to the EQ1-NX, I went with 5-iron through SW. After becoming convinced the switch was a good move, I had a 4-hybrid built to the same specs. It, unlike the 4-iron, fits in beautifully. It plays just like… Read more »
Hi Ronald, I too prefer traditional irons over hybrids. I was missing my 3 and 4 irons in my old variable length set, so I spoke to my club maker who built my EQ1 set and had him build a #2 & #3 Di595 driving iron that Tom offers. They’re longer than my EQ1 irons but I’ve had no issue adjusting to them on the fly when I’ve had to use them. Not sure if this would be a solution for you but wanted to share my solution with you nonetheless.
Hi Tom,
I’m currently being fitted for a set of EQ1-NX irons, also looking to get the 4 hybrid and 3&5 fairway woods but I actually prefer the look of the latest 797hs hybrid & 927hs fairway woods. Is it possible to use these heads with the single length system?
Cheers
Allan
Depending on the weight of the shaft and grip, you could probably play the 797 #5 hybrid at 37″ and still be close to a normal swingweight, thanks to the multiple weight bores in the head. But to get to a 36.5″ length might be tough. Still, 37″ would be really close to the length of the single length irons, IF THE LENGTH OF THE IRONS IS A 36.5″ #8 iron length.
TOM
Tom. I play the single length EQ1s. Fantastic irons. Also have a 5 and 4 771 which are also excellent. Do you have any plans to put the HS300 face into the EQ1s? The HS300 seems to have a more crisp ball response.
Michael
Can’t do that because the HS300 high strength steel is no longer an option. The HS 300 is a totally custom alloy that has been formulated only for the one factory that I use to make the 771 irons. The steel mill decided after Covid that they need to have a much higher minimum order quantity to even make a run of it so that pretty much closed the door on us being able to use that anymore.
TOM
Tom: Not sure if you want to address this, but I am curious on your take from a technical standpoint. The one professional we know of who uses single-length irons–Bryson DeChambeau–recently saw his contract with his club manufacturer lapse. More recently, a major OEM to a set of their traditional (variable) length irons and made him a single-length set. Obvious challenges would be (a) the lie angles–especially since he chooses to build his clubs at a very upright angle, (b) the weight needed to be added to the low-loft iron heads (since they’re so much lighter to accommodate longer shafts),… Read more »
RICH I am well aware that Bryson is a free agent these days now that Cobra have said “good riddance” to him. I’ve not read or heard anything since that as to whether there are any named companies flirting with him or what, other than Taylor Made. At this point I am not too sure whether any of the majors would want to sign him because of several reasons – he would ask for a lot of money, he is known to be difficult to deal with equipment wise, he does for now still appear to want to play single… Read more »
The article I read was in Golf Magazine. Ping took a set of i230s and modified them. I’d have to think it resulted in a Frankenstein’s monster of a set. Yes, it was clearly a prototype for testing; he certainly hasn’t signed a deal with them. I’d have to think the other OEMs have intel on Cobra’s sales and that they’re “meh.” This, combined with dealing with that guy, plus the money he’d cost, tells me nothing will be coming along soon. The fact that he chose to retire from competitive golf–that’s how I see joining the LIV–just adds to… Read more »
RICH No question that the technical challenge of making a set of single length for Bryson from existing incremental length heads would be monumental. But PING has the smarts, the equipment and the people who could do that, I have no doubt. For the lie bending, it is possible to anneal the hosels, which is to heat them to a temperature that is high enough to soften the grain structure to allow for bending. Skilled clubmakers who also have the ability to polish/finish irons can do this to 431 or even 17-4 heads with a MAP gas hand held torch.… Read more »
To he honest, Bryson should just use your EQ1-NX irons and hybrids. It would be much simpler!!!!! If you take a look at his bag he only goes up to 6i with his single length set. I suspect this has to do with getting the correct apex for the “long irons.” In fact, after his 6i he has variable length hybrids/driving irons/fairway-woods. What the heck is the point? With all the tech you have put into the “long irons,” I believe the EQ1-NX are hands down the best single length irons one can get. I currently have a 1.5 index… Read more »
Nathan Thanks very much for your very astute comments. I agree with you that it does not take much time to get used to a longer blade length once you start hitting the clubs. I personally play the EQ1 irons at single length and have since they came out, and I have been a low handicap player (lower before I got old!!!) who always used to prefer more traditional shaped heads. It did not take me any time to get used to the EQ1 blade shape/length. As to your comment/question about Bryson going from all single length irons up into… Read more »
As I understood it, Bryson’s swing plane is extremely steep and his irons are very upright, perhaps more than the EQs could be bent?
RICH
Yes that is true, there is no way that could ever be done. A brand new set would have to be tooled up with the much more upright lie.
TOM
Hi both,
Bryson has his own YouTube channel and posted a video a few days ago showing his clubs. They are indeed the ping heads with the LA Golf shafts he has before. He says he’s working with them, so I assume they’re doing the tuning.
Love the work Tom 🙂
Alistair
From the Bryson YTube channel. . . “. . . the little slot on the back of the hosel allows the club to move through rough easier. . . .. ”
HUH????? Uhhh, the boy needs some serious instruction in the facts of club performance!
TOM ;>)
To be clear, the notch is on the hosel and rather small. It simply could not have the effect Bryson is saying. Deep rough can catch the hosel and cause the club to twist. Really, really deep rough. But that little notch couldn’t have a bit of effect on that dynamic, even if it was designed for that purpose. But it’s not. As I understand it, not notch facilitates bending the hosel. When Ping made its bones with varying lie angles (hence, the colored dots), it did so with clubs cast from the very-hard 17-4 steel. Unless they had molds… Read more »
RICH
There have been several videos made by PING over the years that have shown their factory folks doing quick lie bends with a dead blow hammer, no bending machine. I have no doubt they have some folks who have done this so much over so many years that they will be tons faster than trying to use any type of LL bending machine to do that!
TOM
Hi Tom. I’ve seen a second hand 4 Fairway wood in very good condition, but in the 929 hs serie. I was initially looking for an EQ1-NX wood to complete my iron/hybrid serie. So is it possible to cut the shaft (S2S white 65gr) in order to get a 41″ length ? the actual length of this wood is 42.75″. Thanks a lot
Denis Yes, you could trim the grip end of the shaft in the 929 club to be 41″ and that part would be OK, but the main thing you would have to resolve is the swingweight. The assembled 929 has an established swingweight, done in the assembly of the club. After butt trimming 1.75″ the swingweight will drop about 10 points which is a lot and will most certainly make the club swing with a very light head feel after the length reduction. You will defintely have to increase the headweight to a point where when you swing the club… Read more »
Tom:
Would Denis have to be concerned about how the playing characteristics of the club might be altered with all that lead tape? I would think putting too much (and perhaps this isn’t too much) on the sole would lower the CG and cause the ball to fly with a higher launch angle?
RICH It takes a TON of lead tape to move the CG enough for there to be a very visible change in the launch angle, and by a ton I mean well over 20-30-40 grams of weight on the sole. That, combined with a higher than avg clubhead speed. If Denis has a clubhead speed under 100mph, adding 20g to the sole will barely change the visible height of the shot. This is one of those area for which I coined a phrase some years back – “it takes BIG changes in club specs to make SMALL changes in the… Read more »
Tom: I’ve been playing the EQ1-NX since its introduction, and the previous single-length model since IT’S introduction. I was playing on a course today without great fairway conditions. Not really spongy; just you and a little grass before you’re hitting that fine Arizona clay (ouch). Anyway, I noticed today that the bounce angle for the 5-iron through 9 iron was 5 degrees, lower than my old Ping I10, and much lower than the G425s I used to game. I have a pretty steep angle of descent and today I just couldn’t get good ball-turf-club interaction. But when I dropped a… Read more »
RICH Turf conditions with very little cushion tend to require irons with less bounce to help prevent somewhat of a ‘jarring’ feeling when you make contact with the ground. Mats tend to have some cushion to them, even the crappy mats. More than what you might find with really hard clay soil under sparse turf. Any more bounce such as what so many of the big company irons have would tend to be worse on the hard ground, I would think. I don’t have any real recommendation other than two things – 1) don’t play there anymore, 2) you can… Read more »
Tom: NO troubles at all. I was worried that the bounce might be too little, not too much. You’re right about playing courses with better turf conditions. I certainly have choices where I live, including a military course 3 miles away. Thanks!
Hey Tom would bending the irons stronger help much with that.or is it more of a sole shape thing vs a bounce. I was long time sterling player and tried the eq1s but had this same issue, felt like the turf interaction was extremely blunt and unpleasant and I just couldn’t ever get on with them, the sterlings never felt that way, if anything they maybe dug a hair too much which was fine for me but I’d worn them down so badly I ended up switching back to conventional length irons. Would love to play single length again but… Read more »
KOURT Interesting comments you make. One of the big things that I felt I did a lot better with the EQ1 irons over the Sterlings was the front to back sole radius. I always felt I made a mistake with the Sterlings to not have enough front to back sole radius. I always felt if someone bent lofts lower on the Sterlings that it promoted more of a digger type sole action with the turf. HAving much more front to back radius on the EQ1s, I have always felt that any bend of loft lower would never get to a… Read more »
Tom, I’m interested in purchasing a set of the single length irons and have a few questions. Can you achieve a D5 swing weight with a 36.5”length , 120g shaft and 50g grip? Do you recommend purchasing a shaft that is close to the final desired length, like a factory 8 iron shaft and then trim them all to the same length? What are your thoughts on wedge specific shafts for single length irons? I like the weight and feel of my KBS hi-rev 2.0 130g shafts but wasn’t sure if the kick points would materially impact the longer irons.… Read more »
Blake Depending on where the balance point is on the 120g raw weight shafts you would use, with the heads on spec at 275g, the shafts at 120g, the grips at 50g and the length right at a std 8-iron length of 36.5″, the starting swingweight with no weight added to any head would be right at D0. The hosel weight bore can accept up to a 9g tungsten weight which would put the swingweight at D4.5. TO get this higher, when the heads are ordered from Diamond Golf, you should ask them to hand pick the heads to get… Read more »
Hi Mr.Wishon,
Can you use the EQ1 irons and have different length shafts? Or does the iron only work @ single length?
Danny The whole reason single length even exists in irons is to offer the golfer the opportunity to have every iron be absolutely identical in every aspect – length, total weight, swingweight, balance point, MOI, lie – so that every club swings identical in every way to every other club. The concept is that if every iron swings identically, even with the same stance, posture, spine angle, swing plane, then you have a little better chance of achieving a little higher level of shot consistency. Deviating from that takes away from the identical club nature of a single length concept.… Read more »
The EQ1-NX is designed to be used with single-length shafts. But there are plenty of other Wishon designs that will accommodate your desire for a variable-length irons set. All of them, in fact.
Hi Mr Wishon,
Why didn’t you make the 585PC in single length?
Best regards
JK I did not make the 585PC forged irons for single length assembly because I aimed the model at golfers who are more of a low middle to low handicap player. Golfers who are in that category tend to be the last segment of golfers that would ever think about single length irons. Lower handicap players tend to cling to traditional aspects of golf clubs FAR, FAR more than golfers who are middle to higher handicappers. You can see a few lower handicap players using single length irons but it’s a pretty small percentage. And in truth, lower handicap players… Read more »
Thanks Tom for your reply.
I’m a single handicap and I love single lengths.
it would have been great to have the 585PC in single length, I will stay on the EQ1 NX.
JK
If single-length irons are going to be anything but a niche, players will have to grow up with them. High-handicappers won’t make the distinction and will continue their unsuccessful, off-the-shelf pursuit of the perfect iron. Low-handicappers will be so vested in the game they’ve developed that they would have no real reason to switch. Currently, it’s mid-handicappers (5-ish to 15-ish) with a sense of adventure who are likely to make the switch. (I made the switch about 7 years ago when the first Wishon single-length irons came out, then switched to the EQ1-NX when it became available. I don’t have… Read more »
how much better do you think the new EQ irons are compared to your old Wishon single length. They seem much better to me.
Hey Tom,
I’m looking to try something unique… 35 inch LW-7i, 36 inch 6i, 37 inch 5i, 38 inch 4i… between the EQ1s and the CLAs, is this doable?
Trent
The EQ1 irons can be built to the 36″ #6i, 37″ #5i but a 35″ LW would not be possible because you’d have to add more weight to the head to get it to normal swingweight than what the EQ1 LW head can accept. And there is no EQ1 #4 iron. In the 989CLA irons, you could build all these listed irons to the listed lengths you typed because of the additional weight bores on the back of each head.
TOM
Awesome! Would you see issues with having this kind of setup with the CLA irons?… essentially, if I have 35″ AW-7i CLA irons, do you see ball flight issues?
TRENT The whole reason I began putting more weight bores on several of my models was to allow custom building to a wider range of lengths, shaft weights, grip weights, swingweights. The only thing I would caution you on would be to be absolutely sure you are ok with short lengths such as the 35″ you state for the LW. With some people, getting shorter than 36″ on wedges can make them feel like they have to crouch more over the ball or that they really have to make an effort to stay down on the shot and maintain proper… Read more »
Hi Tom, Huge fan and currently gaming the Sterlings. I bought a set several years ago as a back up experiment as I like to tinker. I bounce between a +1 and 1 hdcp and finally at a place to put some more time in on my game in an attempt to pursue some mid am qualifiers. After much experimenting I have set up my Sterlings with 1/4” increments, SWs in the D-4 range, and basically tip trimming in half club increments to match the half of normal increment between the sets. 5i – 37.5 length 63.5 lie 6i –… Read more »
Colton Thanks so much for your interest! For the set with a little more of a player’s look, if you are planning that set to be single length or in 1/4″ increments like the Sterlings, depending on what shaft (weight) and grip (weight) you want to use, you should be able to do that with either the EQ1’s or any other iron in our design line. I assume since you are a very low hdcp player, you may be more inclined to be using a steel shaft, and possibly more like a normal weight steel shaft. If so, you could… Read more »
What will the swing weight come out to at standard specs?
36.5”length , 120g shaft and 50g grip.
If we use a graphite shaft that is the same weight as traditional steel shafts, such as a 110g or 125g parallel shaft, I would assume swing weights would match a comparably weighted steel shaft without the need for additional hosel weights. Correct?
TSG 36.5″ length + 120g raw weight shaft + 50g grip would be right around C9-D0 as the starting point, depending on the balance point of the shaft. You can never predict that all the clubs in the set would come out to this and potentially either require a little headweight addition or not because there will ALWAYS be +/- tolerances in the headweight, shaft weight, grip weight, as well as how accurately you cut each shaft for length. In EVERY assembly job, you can make a pre-build prediction but that can only be a rough guideline compared to the… Read more »
Thank you. Just needed a starting point. That is perfect.
Do you find these irons generally used by players needing more help, or are more solid ball strikers also migrating towards the single length iron concept?
In your vision, what type of player did you design these for?
Especially as they compare to the 585PC, which I am a huge fan of.
Thank you!
TSG Single length irons are and will likely be far more for players of say, 8-10 hdcp and higher and not so much of an appeal to very low handicap players. ANY player of ANY level could play the single length irons from a performance standpoint, but the very good players would tend to ignore them mainly because the vast majority of such players are very much traditionalists and not at all open to a concept as different or non traditional as single length irons. I designed the single length irons for any player, but mainly for those who have… Read more »
Hi Tom,
Apologies if this has been asked and answered but I couldn’t find a way to search the discussion on my phone. I’m 6’2” and a 37” club puts me in a position that is a little more crouched than what is a comfortable athletic position for me. That’s fine for partial swings but is difficult for free, full swings. It causes me to tend to stand up during the downswing. Your FAQ section says it’s ok to build to 38” but doesn’t seem to recommend it. Can you please clarify? Thanks for your time!
Darren The reason that building the EQ1 single length irons to a length of 38″ is not generally recommended is because of the effect that much longer length would have on the final swingweight/headweight feel of the irons. Every clubhead’s spec headweight is chosen on the basis of trying to achieve a normal range of swingweight that is not too light or too heavy, based on whatever length, shaft weight and grip weight the designer considers the majority of sets would be built with. The heavier the shaft, the longer the length and the lighter the grip, the higher the… Read more »
Tom, do you think this is dependent on the person at the end of the day? I found this interesting and a little surprising. I didn’t know you did not recommend 38” length. I recently got this set and ended up getting them at 38.5”, and I’m using the Project X flighted rifle steel shafts. My fitter felt this was the best set up for me and it’s working quite well. I’m a bigger guy, 6’2” and 245 pounds, so is that a factor that helps this work for me? They did have a slightly head heavier feel than my… Read more »
Shawn Back in 2014 when I was convinced by a golf pro to go to work on creating a single length set all single length sets up to that time were made to a 6 iron length of 37.5″. The problem this created was that the wedges were at least 2″ longer than they were in a conventional lengths set. For many golfers having the wedges that much longer created distance control and accuracy problems. So this was why early single length sets never really caught on and remained a very small niche part of the golf equipment industry. The… Read more »
