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


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

    What impact will adding Jumbo Max grips (roughly 100 grams) have to Sterling (have S2S stiff shaft). What impact does adding these grips to a set with of irons with 125g kbs c tapers. Thnx

    • PAT:

      Assuming the previous grips were closer to the weight of a standard 50-52g grip, the new large/heavy grips would, 1) increase the total weight of the irons by around 50 grams, 2) shift the balance point a good bit up away from the head and drop the swingweight by around 12 points so the clubs would swing with less feeling of the head. It won’t change the flex feel of the shaft though. The main things are of course the feeling of that large of a grip in your hands and having more weight in the grip end when you start the downswing. For changes like this it is really hard to predict what will happen to performance because that is determined by YOU and only your perception for how your swing changes or not from now swinging a club that is 50g heavier and with more weight feel in the grip. Some people like that and some do not and the only way to know is to try one club first. That way if it is not something good for your swing, you only have one club that you have to change back. Sorry it is impossible to be more definitive but when it comes to weight feel changes it is totally an individual thing that cannot be predicted.


    • I have been using super-jumbo grips since they first became available – and before that I made my own by overwrapping “regular jumbo” grips with two layers of thick tennis overgrip tape. That predates my switch to Sterlings, which I got as soon as they came out. So I probably have as much experience with super-jumbo on Sterling as anybody. Also, I have installed super-jumbo grips for many other people, both on single-length and conventional sets. About half the people who try one of my irons immediately ask for super-jumbo grips on their clubs.

      Nobody has ever complained about the swingweight change. In fact nobody has ever even mentioned it. With the big grips, your hand-to-club coupling is much more solid. That gives you extra control over the club which makes release timing less critical. The club position at impact is dominated by the geometry of your setup instead of by the timing of passive wrist uncocking.
      It works especially well if you use a 10-finger “baseball grip”, letting the grip settle deeply into your palms instead of holding it mostly with your fingers. With that setup, the shaft is coupled tightly to your forearm bones, taking the tiny hand bones and fine tendons out of the picture. Swingweight considerations just disappear, because your strong forearms just “own” the club.

    • I’ll add some insights here – the benefit of the Jumbomax grips is a Mitch stated it changes the release for most people. I use the LG Jumbomax grip on my 58* PCF (56* bent) Micro Tour, it is rarely a full swing club – it helps me take the hands out of the swing – similar to how the large diameter putter shafts work. The overall benefit to the grip is the change of shape your hand position on the club. this has helped me and numerous clients reduce/eliminate the chip-yips. No worries on the swing weight.

  3. For Sterling Single Length Iron Fitting, is there someone in NorCal or SoCal doing fittings? I did not see anyone using the search but I thought some time back there was a guy in SoCal area who specialized in the Sterling fittings?

    • JASON

      There really is no such thing as being certified just for single length iron fitting. We do not designate specialty in that. So if you were searching specifically for that, you would not find it. If you head back to the FIND A CLUBFITTER search tool, I can tell you that the best fitters in So Cal are The Pasadena Clubfitter in Pasadena of course and ADS Golf in San Marcos. In Nor Cal the best fitters I have personal contact with are Fore Seasons Golf in Berkeley and Marin CLubworx in Marin Country north of the City. Hope this helps, and thanks so much for your interest,


  4. Tom, I’m very interested and ready to make the switch to single length
    Since ypu taught me clubmaking (1982/83) I understand ypur difference in design and wanted tp ne in the 36.5 lenghth. I wanted tp discuss wedhe lenghth and undersyand you have designed them to be slightly shorter a concept that makes more sense to me. Need shaft advice. Glad to see your continued success.

      Thanks very much for the interest and for letting me know you were in one of the GOLF WORKS schools that I taught “a few” years ago !! It just hardly seems that it can be 36 yrs since then. Wow. At any rate, in the Cincy area, I STRONGLY recommend you contact Bill Weitzel at Conquest Custom Golf. Bill really is one of the very best clubfitter clubmakers in the whole country and I am not embellishing that one bit. If you take the leap to meet with him you will understand what I mean. He can help you with anything related to your fitting needs better than anyone for MANY miles around your area. His contact info is 513-312-1598, and his website is Thanks again and I hope the game is treating you well these days and you are enjoying it !


  5. Hi Tom, I have heard you are not a fan of flighting shafts for the single length irons. Can you explain why a player like me 3 index could not benefit from higher launching shafts in 4-7 and lower launching shafts in 8-sw? I love the idea of the paterson shafts in Edel irons, but I have not hit them. The few single lengths i have hit (not sterling) launch my wedges really high and 5 really low. Thanks in advance!

    • RYAN

      You may be one of the rare exceptions to using flighted shafts to help imcrease trajectory in the low loft irons in a single length set because as a 3 hdcp, you undoubtedly would have a late enough release to allow the flighted shaft to actually achieve more forward bending at impact to allow the shot to take off with a little higher launch angle and spin to achieve a little higher trajectory. Golfers who do not have a very late release cannot make the shaft bend forward more to achieve the higher flight from a flighted shaft design so it is a waste of time for all golfers with an early to midway to even semi late release to try to use a different shaft bend profile to try to get a higher flight with the low loft irons. Since maybe only 10-15% of all golfers have a late enough release to make a flighted shaft do what it is touted to do, that’s one reason I do not advise their use to try to get more height from the lower loft single length irons.

      The other reason is because changing shafts in mid set can very often detract from the main reason that single length even exists. A primary benefit of single length is to have every possible spec that contributes to shot consistency be identical in every iron. If every spec that has anything to do with shot consistency is the same, then we have a better chance of achieving better swing repeatability which in turn helps improve shot consistency. Rarely can you find shafts with a higher flight bend profile design that will be of the same weight, same balance point as the other shafts used in the higher loft irons. So if these higher flight shafts are either a little lighter or more tip flexible which can often mean a different balance point, now you have part of the set with different spec characteristics that might have some effect on the shot consistency aspect of single length. Only experimentation can tell you that. And if you do change shafts in mid set, you can always build them to have the same MOI as the higher loft irons so at least you then re match a huge contributor to the identical swing feel nature of what single length is all about.

      In the end, I feel if a golfer likes the concept of single length but can’t get one or two of the lowest loft irons high enough to be happy with them, then I advise not having those irons in the set at all and substituting more normal length hybrids of the same loft in their place but which are made to have the same MOI as the single length irons. So for example if you could not hit the 5 iron high enough to be happy with it, you go with the 6 to SW in the irons and then for the club above the 6 iron you go with a hybrid of 23-24* loft at a length of not less than 37.5″ built to the same MOI as the 6 to SW are. Hope this helps,
