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 am very interested in your one length clubs. I have watched many reviews and I haven’t seen a bad review yet. My last set up clubs was not fitted, and I am 6’3″, and have trouble with consistency with higher lofted clubs. My GHIN handicap is a 5.9, and I think that the one length may help me with consistency on the higher lofted clubs. I have contacted a club fitter that does work with your company, and most likely am going that route in the spring.

    My two questions – Have there been any technology changes since you first designed these? And, Is there a way to demo a club and make a head to head comparison to other clubs? Maybe my fitter can help with that (looking at using 2nd Swing in Minneapolis). I don’t quite know the process. Looking forward to spring and golf season!

      The only changes I have made to the Sterling Irons design was to add on a Lob Wedge and to re design the SW so it possessed a profile and shape much more like what players are used to when buying traditional shaped wedges for their game. Demo/test club wise, this is a decision for each clubmaker/clubfitter so you would be well advised to talk to the people you are anticipating working with on your fitting to find out if they will do a test club or two for you as a part of the process. Many will do that but it is an individual decision for each clubmaker based on how they wish to run their business. But I will say that taller people do tend to do better and adapt better to single length in large part because of the high number irons + wedges now being longer than what they had been used to which leads them to more comfort over the ball and an elimination of feeling too crouched or bent over with these clubs. That and of course the main principle of every iron being a duplicate for every swing feel element and the chance of that leading to a higher level of consistency with the irons.

      And stay warm up there. I have a bro in law in Alexandria, MN and a sis in law in Fargo and we have been hearing about the intense cold you all have been suffering through. So much that our bro in law is bailing out and heading to FLA this weekend for 2 weeks !! Take care and thanks so much for the interest !

  2. 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)?

      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,

  3. 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.

      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.
