STERLING
SINGLE LENGTH IRONS
A Unique Set Design to be Built to One Length for all Clubs to Deliver a Perfect Match of all Elements of Swing Feel for shot consistency.
Features:
-
- Single length construction ensures all possible elements of swing feel are identical for each club in the set – same MOI, same total weight, same headweight, same balance point – to offer the chance for improved shot consistency
- Identical length and lie allow the golfer to use the same stance, same posture, same swing plane forimproved shot consistency
- Optional high COR #5 hybrid with high COR #4, 5, 6, and 7 irons offer proper distance for the low loft clubs at the shorter single length. Other single length sets may lose distance with the low loft clubs
- Conventional cast carbon steel in the #8 to gap wedge with 5* loft increments blend with the high COR design of the low loft clubheads to offer proper distance gaps and proper
distance with the high loft clubs. Other single length sets may generate too much distance with the high loft clubs - Available in a #5 hybrid or #5 iron to match the player’s desire and ability, with #6 to 9, PW and Gap Wedge and Sand Wedge
- Sterling Irons® Single Length clubs can be built to 36.5”, 36.75 or 37” length for each club as fit by the Clubmaker for the golfer’s comfort and preference. Contrasts with most other single length sets being created for a 37.5” length – which can generate too much distance with the high loft irons
- Intended to be custom fit with any Wishon Golf S2S iron shaft model and flex to meet the swing speed, transition/tempo and release point of the golfer.
- Sterling Irons® hybrid uses standard iron shaft (.370)
- The #4 iron should only be used by golfers with a #5 iron clubhead speed of 85mph or higher to be able to make the club generate the proper trajectory and height to be able to carry the ball further than the #5 iron
- Available in RH (#5 Hybrid, 4-9, PW, GW, SW) & LH (5-SW); New Blade Wedges (LW, SW) available in RH only

Hi Tom – hope you’re well and staying safe Wonder if you could help… I’m keen to pick up a set of Sterling single length irons and was looking at 5h-SW based on some previous advice. As you can imagine I’m looking to fine tune the set as far as is reasonable but COVID-19 obviously creates challenges. My stats are Age 51 Height 179cm Wrist crease to finger 18.5cm finger length 8.25cm Wrist to Floor – 91.5 – 92cm 7 iron carry 140 -145yds Strength slightly above average Medium tempo with slight aggression I play with a 3/4 swing (Don… Read more »
JIM Many thanks for taking the time to stop by to ask questions about the fit of the Sterling irons. Obviously as long as your fitter has good experience, being able to work with you in person to see and evaluate your swing motions and to obtain your feedback will be far better than what I can do from afar. Based on your measurements all being correct, your length would be 36.5″ (normal 8 iron length) and the indication is you would need an upright lie angle. However your clubfitter will likely do a dynamic lie test which will be… Read more »
Hi Tom, i currently play 4 to LW SSL irons V1 with S2S white stiff shafts length 37″. I also use 919 HL driver which i beleive is 13 degrees. Now the new EQ1-NX are available i was thinking of replacing my hybrids and possibly my 4/5/6 irons with a combination of the new woods and hybrids all at single length. My questions are: 1) Would i need to make the wood and hybrid head weights 274g the same as the V1 irons? 2) Can I use the same shaft length in the woods and hybrids as my V1 irons… Read more »
ROB Very important – the new EQ1 woods are not designed to be built to the same length as the hybrids or the irons. You can’t do that and expect to get close to the normal fwy wood distance so the woods have to be their own separate single length vs the hybrids and irons. But the hybrids can be made to be the same length as the irons because the hybrids have the capability to be able to get the head weight up to the same level as the irons with multiple internal weight bores in the heads. So… Read more »
Hi Tom, Thanks so much for your reply. I’m so glad i asked now. I am surprised by the loft gap between last hybrid and first iron. Thats wider than i would have chosen. I would have tried to keep it more consistant between all clubs i.e. 4 degrees. The combo’s above of 2 woods, 1 hybrid then irons is great, but is it possible to use more hybrids? Or would that cut out too many irons? i.e. 4h, 5h and 6h would the first iron be 8 iron? I am loving the SSL irons and playing so consistantly with… Read more »
ROB If a golfer has a normal to below normal clubhead speed, it is very common to see a head with a lower and more rear center of gravity location generate more carry distance than an iron that has the same loft or a loft that is +1, 2, 3 degrees higher. This is because the lower and more rear CG location jumps the ball higher in launch angle. When the ball speed then kicks in the ball can keep flying up and up on that higher launch angle to achieve better carry distance. That’s why in many sets the… Read more »
what is the blade length? thanks
WIlliam Wish I could post diagrams to make this easier to follow but that’s not possible so words will have to do. Blade length is the length of the clubhead from the end of the outer edge of the toe end of the iron head to the bottom of the hosel as measured along the ground. When you look down on an iron in the playing position, the blade length is how long the head looks to you from heel to toe. Very short blade length compact size irons will have a blade length in the area of 75-76mm while… Read more »
I bought a set of these in May ’20 and have now played 4 rounds with them. I play off a 15 handicap and ball striking consistency has always been an issue for me. These clubs take out the need to consider ball position and distance from ball for each club and therefore have already greatly helped me. As for chipping/pitching into and around the greens, these have come into their own and given me greater confidence and consistency. These are a fantastic set of clubs and I absolutely and thoroughly recommend these clubs to anyone that may be looking… Read more »
NIK
Wow, how great is that to be able to hear how much you like the new irons and how much more they are helping you to enjoy this great game a little more. Being able to hear this is without question the best reward I can have in my “work” which as you can tell from the quote marks has never really been work!! Thanks much and the very best to you for many more shots and rounds that bring a smile to your face!
TOM
Bottom bore to ground is 1/4-inch lower on the Sterling 5-Hybrid than on thre remainder of the irons.
Tom, I notice that there is a new single length iron set from Wishon Golf. The EQ1-NX. I am a senior golfer with a handicap of 12. M 7 iron goes 140 yds. Which of the two sets do you believe is more applicable for me? I need to get my irons higher in their trajectory.
JOHN Thank you very much for your contact and your interest in what we are doing. We appreciate that very much. I need to tell you that if your interest is more immediate, due to continued workforce reductions at the production factories, the first deliveries of the new EQ1-NX clubheads has been delayed another month to mid July. We’re sorry but the factories have never recovered the workers that stayed home when lockdowns went into place in February. So if you were planning to look seriously at a new set before August, the Sterling irons may be the better choice.… Read more »
Hello Tom!!
A couple weeks back, I had Terry at T’s Golf in Hazel Green Alabama build me a set of Sterlings. We used a SK Fiber Tri-Tec regular shaft with Lamkin Sonar Std+ grips. I have to say that these irons are game changers. I have made a drastic improvement in my consistency. But, I now see an issue with my club selection in the future. Do I play these or my 771’s with SK Fiber Pure Energy shafts??? I will admit, this is a great problem to have!!
TIM
Given all the problems that can beset people, you certainly do have a very good problem!! That’s very nice for me to have the chance to hear that and thanks so much for taking the time to not only let us know of your “problem”, but first and foremost to have chosen to work with Terry for your fitting needs. He’s very good and I am pleased that he chooses to fit golfers with my designs.
Thanks much and the very best to you in this great game,
TOM
hi tom – was hoping for a bit of insight between 2 shafts – the ns modus3 120 and the ns pro 970 (titleist). i think these are similar, but have no data on them and was hoping you might be able to tell me. i like the 120’s but think they’re a bit much for me in an s flex, and while i thought about moving down to an r flex, i saw the ns pro 970 and thought about staying in a s flex with them. my thinking is that the ns pro 970 has a bit more… Read more »
TOM I have bend profile measurements on the Modus 3 120-s but I have no information on the 970, mainly because if this is a proprietary Nippon shaft for Titleist only, the policy has always been the shaft maker can’t provide anyone with any testing samples of an OEM shaft and of course the OEM for which it is made is never going to make any of their shafts available for testing or measurement. I can tell you from the data I have that the 120-S is not very butt stiff but it is reasonably tip stiff. Not as tip… Read more »
hello Tom. I am 63 years old and I started golf for about 4 months. After a lot of research into single-length clubs, I decided to take the plunge and equip myself after a ckeck-up with André Thaon. I am very excited to play with your irons. Sorry for my bad English.
Regards Regis
REGIS Thank you very much for taking the time to visit our website and send us your comment message! We appreciate that very much! I can guarantee you that the very, very best decision you have made is to work with Andre for your fitting needs. Andre is without question one of the very best clubfitters in the world and I am NOT making that up just to tell you that. Andre is as good as a clubfitter can be. Period. So you will for sure end up with the best set you have ever played because Andre will take… Read more »

Great review of the Sterling’s. I know it’s a little late but I think this endorses the concept and hopefully will see even more people try the new EQ1- NX.
I’ve played the Sterling’s since they first arrived and think they’re the most consistent irons I’ve ever hit.
I hope you are doing well and staying away from the virus. I have ordered the Eq-1 iron heads, 2 of the hybrids, and the 3-wood. I have also ordered the Nippon 950 GH Neo shafts for the irons. Since it appears the shafts will be in this week, and the EQ-1 will not arrive until June, I have thought about reshafting the current set with the new shafts to try them out. Is the hosel depth the same for the new irons so that I can just extract the shafts from the old heads and install them in the… Read more »
David No problems here with the stay in place as ever since Diamond Golf took over the brand and I became a solo consultant, I was never around any people during my days anyway and no one ever walked into my workshop/office. So for me and my daily routine, nothing much has changed other than the sadness of reading how much this is and has really affected and damaged the lives of millions upon millions around the world, which is a terrible tragedy. I think about that every day and hope that wisdom will prevail to get us all out… Read more »
I have been playing Cobra F-9 OL for about 2 years. My lie on the clubs vary:
5i- 62.5,6i-63.0,7i-62,8i-62, . My 9i is 61degrees and they get progressively lower with the SW being at 59. I feel I need to tweak my lie angle howevet, I am not able because of the type of steel in the F-9. I feel I would want all my lie angles to be the same(61 degrees) Is that a bad idea?
WES In truth, all lie angles for all sets whether single length or conventional incremental length, should be individually dynamic lie tested and then any necessary bends made to each iron. It’s unusual for the irons in a single length set to be set up with different lies because more often than not the golfer will demonstrate the same stance, posture and have the same spine angle and hand position through impact. However there are always going to be people for whatever different reasons that may end up with somewhat of a different spine angle or hand position through impact… Read more »
One of the many things I love about single length is that you can discover lie angle problems just by playing. Case in point: One of my wedges was consistently ending up left of target. At first I attributed it to ball-above-feet or overcooking my swing, but the mitigations for those problems weren’t working and then it finally dawned on me – it is only this one club that I am pulling, the others are going straight. Duh! Lie angle. I didn’t even have to measure the dynamic lie, I just had to compare to any one of the other… Read more »
I love my single length irons. I really wish you would design me a 3 iron.
Jeff I appeciate your interest and your enthusiasm for your single length set. I can’t lie, the chances of there being a 3 iron in the single length set are about the same as having a snowstorm in July in Phoenix. Sorry to make light of it but the reason I did not include a 4 iron in the new EQ1-NX single length iron design is because the demand for the 4 iron was smaller than what is normally required to justify the development/tooling/inventory and of those who did get the 4 iron, we estimate as many as half did… Read more »
Hello Tom. I am a Sterling irons player and very satisfied!
Tom my question the 919FD @14 deg. This is described as a mini driver. I’am a 71 yr old average swing speed using a 10.5 460cc
Ping driver.
What should I expect in using the 919FD. Distance etc.
My goal would be to use a club that’s easier to use.
Steve.
Steve Thanks much for your interest and your support!! Very much appreciated for sure! If the 919FD is built to the same exact specs as any other titanium driver – same length, loft, shaft, swingweight/MOI, grip, total weight, etc – it will hit the ball as far as the driver. Just because the head is smaller, that doesn’t change anything with respect to distance because from the head’s standpoint if the COR, loft, bulge/roll are the same, and then if the assembly specs are the same, then it’s an equal performing driver with the only difference being the off center… Read more »
Hi Tom. I hope you are well and safe. I am 71 and have not been able to play golf for many years due to physical issues, surgeries and an arthritic disease. Last year I decided to try again, I miss golf too much. I am intrigued by two concepts, the single plane swing and single length irons and hybrids, shorter driver. May I ask two questions? What would you recommend with respect to club length and provisional static lie? I am 5’7″, wrist to floor 33.25, hand size 7 5/8″. Second, in your opinion should I order the Sterling… Read more »
Bill: You most certainly have my sympathy and my hope that you are able to get back to enjoying the game. I turn 70 late this year and I know from my own history I am facing the day sooner rather than later when I will likely have to accept I may not be able to play or play nearly as much for some of the same reasons that have kept you from the game. So I can relate what you are talking about when you say you miss it too much. May you be SUCCESSFUL in your return to… Read more »
Tom,
I am so grateful that you took the time to answer my questions. Your careful, personal and insightful answers to everyone’s questions is one of the main reasons I am interested in your one length irons rather than any competitors. You are spot on that my club head speed is now below average. Thank you for the advice and I am eager to buy the EQ1 NX irons when they are available.
Hi Bill, I work with older golfers quite a bit. I’m a proponent of, and personally use, both single length and single plane. I have found a couple of things that are helpful for older people. The first factor is to stand more upright. Us older folks just can’t bend over and hold that crouched position like the young whippersnappers. Single length irons can be very helpful in that regard, as the extra length in the wedges lets you adopt a posture that is less stressful. The second factor is supersize grips, like JumboMax or Diamond Tour DTG Super Oversize.… Read more »
Hi Mitch,do you use palm or ten finger grip,as per Jack kuykendall? If so would separated hand grip require slightly longer club?
Hi John – Yes I use a 10-finger palm grip, and it does benefit from extra length. The right hand moves down about 1 inch compared to an overlapping grip, so the clubs need to be between 1/2″ and 1″ longer to maintain a comfortable spine angle. My Sterlings are built to 37.5″ which is longer than Tom recommends, but it is the 8-iron length from my pre-Sterling set. That length results in a high swingweight, but that is mitigated by the use of lightweight shafts (I use Wishon S2S White graphite) and the counterweighting effect of the heavy supersize… Read more »
Tom It’s Rishi Again. Everyone seems to have been able to see the eq1’s but I can’t find them online! Is there a link I get get to see them!
Hi Rishi,
You can find the EQ1-NX irons here.
Best Wishes,
Ash
Tom, I see that the new EQI irons are available in in right hand only- are there any plans to add left hand clubs in the future as were available in Sterling?
RAY
Yes for sure we began to talk about that pretty much from day one of the EQ1 project and we will do these in LH. But it probably won’t be this year because of several reasons, not the least of which is the fact we need the world to begin to get over the virus (of course everyone needs this!!) so there is more of a golf business out there to potentially cater to with equipment offerings. Hopefully next year for the LH versions.
TOM
Thanks- wishing you the best and a quick return to “business as usual”.
Woohoo! Diamond Golf is now accepting preorders. My order is in. I’m so looking forward to the new design – which looks great – and to playing golf again.
Hi Tom, I’d like to ask you about playability/game improvement in regards to your single length irons. Last season at 49, I finally went from playing three rounds every six years to playing three (9 hole) rounds per week. About six weeks into the season, I realized the clubs I had were too advanced for me and took the plunge into single length. I built up a set of irons with the cheapest one length heads on the market and haven’t regretted one penny of my investment! I’m currently at a 34.5 HC and was consistently 55 or under by… Read more »
ART Thanks very much for your interest, much appreciated. You know, there is an old saying that is very much applicable to golf clubs – “if it isn’t broken, don’t go out and try to fix it.” From what you say, you hit the in1zone irons well and you are happy with the results. In all honesty when it comes to irons, when a golfer truly does hit a particular model well, a custom fitting in a new iron set usually is not going to represent a remarkable difference. At this point, what I would recommend is that since you… Read more »
Thanks so much for the response Tom! I used to custom boot fit at a boutique ski shop and I totally hear you. I was always more concerned with what worked for the customer more than sales numbers. I had a feeling I was still a few years away from moving to a more player’s oriented design. If possible, I would like to bend your ear a bit about club length and set make up. Firstly I’m a bit of an anomaly for fitting: I’m 5’10.5″ but have a 35″ inseam and only a 33.4″ wrist to floor. All arms… Read more »
Art Then you would fit right in here in Durango, Co since we have our Purgatory ski area just 15 mins up the road and Telluride and Wolf Creek are within an easy drive – well sort of an easy drive for a mountain person if it isn’t snowing!! I’m OK with many different options for iron length with one proviso – those lengths have to be COMFORTABLE to the golfer in the address position AND in the impact position, and they also have to be able to combine with the lofts to deliver a reasonably consistent, usable distance gap… Read more »
Couple fitting questions on the new hybrid set. Will bottom of bore be the same with the new single length hybrids? Or will they have their own spec. Just curious on shaft trimming if you build say a 5 hybrid at the same length as the irons. What about lie angle on hybrids? I’d assume if you’re matching the hybrid to the irons you’ll want the same lie angle? Now what happens if you have say a 7 iron length iron set that’s 3 degrees up and you stop at 6 iron. Then would you go 4 and 5 hybrid… Read more »
Kourt Good to hear from you and hope you are staying safe and positive through all this. The new EQ1-NX hybrids are a little different than what I did with the Sterling #5 hybrid. First of all of course, the EQ1’s are a #4, 5, 6 while the Sterling was only a #5. So there are more options for golfers with avg to below avg clubhead speeds to use hybrids as part of their single length set vs before. I did increase the BBTG of the EQ1 hybrids by 1/2″ so if you did want to use the same iron… Read more »
Hey Tom I’ve been playing your sterling irons for years. Love them , nothing else can compare. Can’t wait to see your new set. I’ve been checking everyday! Any idea when we can get a look! Cheers
Rishi A.
RISHI Thanks so much for your interest. Information on the new EQ1-NX irons, hybrids and fairway woods will come, but we are not 100% when because of the effect the shut down from the virus has been having on businesses. Diamond Golf who manage and distribute my Wishon brand products is closed as a part of the country wide lock down in the UK imposed by their government. They are operating with everyone working from home except a very small inside skeleton crew to handle things that can only be done at the company so clubmakers can contact them for… Read more »
Tom,
Will the bottom of bore to ground measurement on the new single length iron heads be the same as the Sterlings?
Thanks!
RAY
Yes, the bottom of bore to ground dimension on the new EQ1-NX irons is the same 1.5″ that it is on the Sterling irons and on every other iron in the Wishon Golf product line. I like keeping those things standard so the same shaft model/flex can play the same regardless which model of iron a golfer may choose.
TOM
Tom,
Having played your Sterling irons for the past few years, you new set could be the thing to make me update my bag. I hit the Cobra’s a couple of times and although they felt nice, I just didn’t get their logic in using different lie angles throughout the set. Regarding your new irons, can you share a photo, we are all dying to see what they look like!
PS. I play your set at 37.5″ with 105g graphite shafts. Would I still be able to get a set made up at a 1850 moi?
Error, the shafts were cut to 37″ length (with grip closer to 37.5″), and MOI was 2780.
KEN There is no logic in using different lies when all the irons are the same length with the same exact shaft and ball position. Even without reading whatever you read that says that, I cannot come up with any shred of an argument to defend that position. Lie is ALWAYS chiefly determined by the length with small effects coming from the shaft and ball position. In a normal incremental length set, when the irons are different lengths that makes the lie different from the get go. Different lengths also makes the shafts droop a little differently from each other,… Read more »
Hi Tom
Is there any plan to add the 4 iron into the EQ 1 line maybe with the same weight addition concept as the hybrids so that it could be built to a normal length driving iron or into the SL setup since the 590DIH has been discontinued?
Thanks
Not at this time do we anticipate adding a 4 iron to the new EQ1-NX single length iron set makeup. In all honesty we should never have had one in the Sterling set because at an 8 iron length, the clubhead speed required to properly elevate an iron with only 20* loft is beyond the clubhead speed of 98% of all golfers. That proved out with the Sterling 4 iron where not enough people bought it to make it worthwhile to develop, and of those who did, half of them at least never could hit it well enough to have… Read more »
Hi Tom You are right that most people can’t elevate the 4 iron too well and with almost every client that I worked with they only went up to a 5 iron max. I think I am in the lucky group as I can elevate the sterling 4 iron really well and routinly hit it 210 plus in the summer time, longer than I used to hit. It’s also a very dependable club off the tee on tight holes. I have also read that there is a new driving iron coming out named Di595? Is this an open cavity design… Read more »
The only people without an 85mph+ clubhead speed at 8-iron length who can elevate the 4 iron are those with a much less steep angle of attack. But even with them the required speed is still 80 or a little over that. Yes the new Di595 is a 2 piece hollow body design with a high COR face. With that construction we were able to push the CG lower and more back from the face while bumping up the MOI in the process. That new driving iron will be in a #2 and 3 – no 4 for the reason… Read more »
Tom Thanks for the detail explanation. It really helps to know the engineering, testing and thoughts that go through the design of the clubs from the designer himself. It not only helps the golfers but also fitters to have a better understanding when going into fittings. I have one more question on how the hollow body construction irons lowers the CG. I understand how the extra material pulls the CG further back, but the extra material on the higher portion of the hollow body would likely raise the CG? Could you explain a bit more about how the could be… Read more »
LINCOLN I can’t post any photos here on this comments section of the website so watch for an email to come to your gmail account with a photo which will do a better job of explaining this matter of hollow iron vs MOI. But basically, you are eliminating a huge amount of the weight mass that was in the middle areas of the head to be able to position that anywhere you want it AROUND the middle areas of the iron. So yes, there is some weight at the top of the head but there is a huge amount of… Read more »
Hi agin Tom. To piggyback off of Dave’s question, & follow up with mine from last week, would I be able to have Gary Cottrell (Golfers Advantage) rework my Sterling 4 iron & lob wedge to work with your new single length irons? I’ve never cared much for hybrids (also got a hole-in-one with my Sterling 4 on its first 9) & went to single lengths originally due to a lousy knee which didn’t/doesn’t like squatting down for the shorter clubs. I’d hate to invest in a brand new set, then have a regular (now seemingly super short) lob wedge… Read more »
Kevin Yes, any changes in the Sterling 4 iron to make it achieve a proper distance gap between it and the EQ1 5 iron would be minimal and should only include a slight loft tweak on the 4 iron. The change would likely be so small that it would not have any effect on the sole angle of the 4 iron from a performance standpoint. I would recommend to have a good feel in your own mind about how the Sterling 4 iron distance and height is compared to that of the EQ1 5 iron BEFORE you head into see… Read more »
I found this to be true for me. I swing the driver at about 107 so I thought I could handle the Sterling 4I. But no, I don’t hit is as well as the 5I–lower and less carry. I suspect I will acquire the new clubs when they’re available, but I’m not going to miss the 4I. I’m not going to miss the LW, either. I got the second version, and it’s a good club. But it isn’t versatile. You can open the face, you can choke down on the handle, but you can’t do both; it’s too upright for… Read more »
