  1. Hi Tom,

    So, for probably the first time in my life, I’m doing some serious research before purchasing a set of golf clubs.

    I’m turning 40, and I have a 20 year old set of taylormades that I have been pretty happy with to be honest, but it’s time for an upgrade. I would be about a bogey golfer (playing 10-15 rounds per year the last 10 years since the kids came along and the short Canadian golf season. My kids are now getting into it more – hence the reason to finally upgrade.

    I have devoured your online content and youtube videos, and am fully convinced of the benefits of a true custom fitting as well as the quality of the Wishon products. Distance is no issue for me (150 yard PW, 210 yard 5 iron, 280 yard Driver). Full swing irons are the best part of my game (miss with a draw). Chipping is the weakest (need to play more!) I’m really looking for control and feel – and I’m hoping consistency will come with more playing of course!

    It seems most OEMs Drivers and woods are maxed out, and extremely similar – check mark to Wishon for a custom fit, affordable option. My real question I guess is on the irons.

    You see, I am LEFT HANDED and shoot LEFT HANDED. I think it’s a particularly Canadian affliction and more than 50% of Canadians pickup a hockey stick left handed and something like 20-25% of our golfers are on the sinister side of the ball.

    I realize your sales statistics don’t lie to you, but I’m wondering if there will be any additional LH options in your 2020 lineup (forged?) or if you would give an edge in feel and control to your 771CSI vs 979ss. I suppose I’m open to trying the Sterling, but it seems such a dramatic move to commit to when you are spending more money. I would hope my next set to last at least 10 years, with a goal of moving to 20-40 rounds per year.

    I love that you personally respond to messages, and I also understand if you don’t want to let the cat out of the bag about your newest offerings, but some more options for us lefties would be awesome!

      Good to hear that you’re on the verge of being able to get into the game more. Here’s hoping that your kids get hooked and like the game a lot so you have them to grow back into the game with! Now the tough part. Your observation about the statistics of clubhead demand and development are unfortunately spot on. Never in all my decades of designing clubheads has any one of my left hand models ever seen more than 8% of the demand the same model has in RH. And that’s even with us having sold to a good number of clubmakers in Canada (and Sweden where the LH %-age is higher as well) over the years we have been in the business. So it is a sad fact that we just can’t do very many of the models in left hand. Worst of all on that list are the forged irons. Forging tooling costs 6 times what the tooling costs to do an investment cast iron model so I have never in my career been able to offer any of my forged irons in left hand. Of the three options of 771, 979 and Sterling in left hand, unless the single length concept has really bit into you, you should think more about the other two. Single length is certainly a valid concept and many people do very well with it. But if you even have a slight doubt about it, I would stick with conventional lengths. Of those two, the decision comes down to distance – if you want the most distance with the most off center hit forgiveness you go with the 771 because of their high COR variable thickness face. The 979 are more traditional in the sense of being one piece investment cast with a normal deep cavity back. But for sure if you do find a model more to your liking such as a left hand forging, then by all means go that route but do be sure to try to work with a good, experienced clubfitter for yours and your kids’ needs in the game.

      Thanks so much for your interest and for having dug up some of my work over the years. I really do appreciate that very much. And I wish you the VERY BEST in this great game as you get back into it with your kids to share the enjoyment!

  2. Hello Tom. I was recently fitted for irons, having tested Ping G400, I200, Taylormade M3, and Mizuno JPX900. My best LM results were with the G400’s with the Project X 5.5 shaft. My handicap is 14 and have been playing my PE2’s since 1988. One key thing determined by this fitter is that the +1/2 inch shaft length on my current irons is not needed. He said it’s borderline based on my physical measurements, but that the LM data shows better club head speed with regular length.

    I’m now looking at other options in irons and several folks on my golf forum have suggested looking at Wishon. At first glance/review, it would appear the 771CSI irons might be the most similar to the G400’s? What are your thoughts? Thanks.

    • BILL

      My apology for the delay in responding. The day your post came in I took off for a week and a half and just got back to it today. Sorry for any inconvenience.

      It appears the G400s are a higher COR iron design so yes, you could say that at least from this standpoint the two models would have some similarity. Do take a look at the lofts on the two models. I designed the 771’s some years back and like most of my models they tend to stick around for a lot more years than do the big companies’ models. Thus when I designed the 771’s the lofts I chose are now a little higher per iron than what so many of the big companies are doing on their game improvement irons released in the past 2 yrs. For example the 771-6 iron is 30* and then everything goes up by 4* from the 7 to wedges. Some companies today are making their 6 iron with 26, 27, 28* loft and setting the others in accordance with that. In that case if the G400s are stronger lofted, you’d not hit the same number in the 771 as far. Something to bring up since a lot of players don’t think about that when looking at new iron models.

      I might also suggest you consider going with 3/8″ increments between irons starting from the 6 iron and not the usual half inch up and down the set. This way you get a little more comfort over the ball with the 8, 9, wedges but not so much that it causes any distance or shot performance issues. And then with the 5 and 4 if you go down that far, these end up a little shorter than in a conventional half inch increment set so they can be easier to control.

      Hope this helps,

    • Tom,

      Do the 771CSI irons stack up to the new current lot coming from the OEM’s. Allowing for the jacked Lofts (which basically seem to shift an iron set 1 club) how’s the offset and forgiveness performance on mishits for a high handicapper like myself?

      Also I’m thinking of working with Bill Wietzl from Conquest Golf in OH do you know Bill?

      Than You


    • MARK

      Yes for sure I have known Bill W personally for a very long time in this side of the golf equipment industry. No BS, he is without a doubt one of the ten best clubfitters in the world and I am not embellishing that one bit. You’ll come away with the very best fit possible, bar none.

      And yes, the 771’s as well as most of my game improvement iron designs are now higher in loft per head number than the recent models from the major golf equipment companies. I can gripe and bitch all I want about how cheap and greedy it is for these companies to go so far into the shrinking loft syndrome that 5 irons now have 21, 22* loft as their way to fool golfers into thinking they are hitting the ball longer because of “new technology”. But it is what it is and I may hate it but I have to live with it and correspond to it. So I am in the process of designing several new sets of irons for my line for 2020 that are only “needed” to be able to prevent unknowing golfers from thinking that my irons are “deficient” because they can’t hit them as far as they can the recent offerings from the other companies. At this point the primary 5 iron loft on all of my game improvement irons is 26* so I now have the “privilege” of being one club “shorter” than the recent offerings from the bigs. Bill can bend that down 2* without it affecting the performance of the sole angle but I would not go down more than that or else the offset increases visibly and the base of the hosel begins to look curved from that much bend. And no durability issues whatsoever with a bend for lower loft.

      Thanks very much for your interest and for putting up with my griping about this issue.

  3. Tom
    I want to gain one club length with the 771s vs my current non COR irons of the same loft. My driver swing speed is 93 MPH. Would the 771 and two degrees stronger loft accomplish this?

    • Bruce

      That is impossible to predict unless you know for sure what the loft of both the current irons and 771 irons happens to be. ALL clubheads are subject in their production to a normal error tolerance of +/-1* and unless you have someone proficient in the use of a proper specs measurement gauge to check the heads of both sets, you can’t know what the loft starting points are for each head for both sets. Second, how much distance any golfer gets with a high COR face depends on their clubhead speed. Slower swinging golfers get less actual yards of increase from a high COR face than do higher speed players. Gut feel based on decades of working in this technology tells me that if the lofts are truly the same between both sets, given your clubhead speed you might see a 2* loft decrease on the 771’s give you about 2/3’s of a full club length improvement with the 771’s over the low COR irons. BEst I can do here for you in that guesstimate.

  4. Hello,

    Have a question/request for your opinion: I’m a 7, 60 YO, been playing CB 57s and like them. Been looking, however, at hotter faced clubs and discovered yours… I like the look of the 771s, but was wondering if there’s a way to get them less offset?

    • TOM:
      Thanks very much for your interest, for sure. Once a clubhead is designed, its offset is set forever and cannot be altered. To change offset in the 771CSI or in any existing clubhead would require new tooling dies to be made from scratch with the offset change in the dies. You can change offset by bending the loft angles, but you cannot change offset while keeping the lofts as they are. Theoretically it is possible with a completely new type of bending fixture and machine, but as of now such a unit does not commercially exist in the golf equipment industry. Sorry about that.

  5. Hello Tom,

    Some questions about Lie Angle
    I got a full set (5-PW) of 771CSI Irons last June.
    I decided to have them bend 2° up to have the same 4° gap between my wedges. So the PW is 48° instead of 46° the 9 iron 44° etc.
    My swing at that time was very much over the top – outside in. So we bend the Irons to a Lie angle of 68° only the 5 Iron to 64°
    1. The lower the loft the less the lie angle impacts the ball flight? Correct? So if my 5 Iron would be 58° vs 64° I would not feel a lot of difference?
    2. I improved my swing and I stay now in the same plane (quite steep) but especially with the short Irons and PW I produce a PULL quite often. The ball impact is perfect and the length too but it is a straight ball to the left. Could this come from a non adapted Lie Angle?

    Thank you for your support.


    • Michael

      Yes, the lower the loft, the less there is a misdirection angle off the face when the lie angle is not fit correctly to the golfer. But because you hit the low loft irons farther, it is true that the smaller misdirection angle can be multiplied into an off line shot simply because the ball is flying farther on the smaller misdirection angle. This is why we always want to dynamically fit the lie for each iron and not ignore any of them in the fitting process. The only way to know for sure that the lie angle is not affecting the direction of the shot is to perform a dynamic lie test on each iron, one at a time. You can go to You Tube to search for “Dynamic Lie Angle Fitting” and you can find several videos to show how this can be done by each golfer to check the fit of the lie. If you find the lies are right, then you know the pulled shot has to be coming from another part of your swing.
