TIM I work out of my R&D workshop in Durango, CO in my semi-retirement consulting position for Diamond Golf and the Wishon brand so I do not have access to the account records of Diamond Golf. I sent them your post and asked them to follow up with the information you seek. They should be on top of that in a day or so. I don’t have photos of any of the models because all of that work is done over at Diamond’s HQ in the UK but I did ask them to send photos if they have shots other… Read more »

GREAT to hear that the first impressions are solid and positive!! That brings a big smile to my face, though it is probably not quite as big as the one on your face after hitting shots with the new sticks!! Thanks for the input and the very best to you for many, many more great shots with the new clubs!

Sylvain Thank you very much for your interest and for choosing to open an account with Diamond Golf. We appreciate that very much! I first would like to say that I am sorry that we have not been able to offer any of our forged carbon steel iron models in left hand. Unfortunately we are a small specialty design company and with the typical left hand demand in the golf industry worldwide we simply would not be able to sell enough left hand forgings to offset the high cost of tooling dies and production. The die costs for a forging… Read more »

Patrick There is a big difference between any of the forged carbon steel iron models in our line and the 771CSI irons. The 771s are a full blown super game improvement iron design while the forged irons are definitely far more in the traditional “lower on the game improvement scale.” The 771s are investment cast from carbon steel to enable bending the heads for lie and loft purposes to be super easy and wide ranging. A thin high strength steel face plate is welded into the 771 body and that is the real key to the game improvement performance of… Read more »

That would not be my recommendation because, 1) the lofts of the old 550C are even higher per number than those of the 771’s; 2) the face of the 771 is high COR while the face of the 550s is not. You’d see distance gapping issues between where the 771 ends and the 550 begins in the set makeup. And impact feel differences too because impact feel is different between a thin, high strength steel high COR face and a thick forged carbon steel face. Best to stay with the 771 throughout the set.

Alvaro Thank you for taking your time to stop in and join us to ask your question! Lots of great golf in your area so I for one am very jealous that you have such an array of good golf to play up there!! There is no question that the 771CSI irons will achieve a higher smash factor because their faces are a thin, high strength steel for a higher COR. The 565’s are forged carbon steel with a conventional thicker face by far than the 771s. The Sterling 7 iron is the same exact high COR face as is… Read more »

ART That set makeup is workable based on you knowing the distance gap change that will happen. As to which iron to bend, stronger or weaker, it is always better when you want to do that to bend the lower number higher in loft because that increases bounce whereas bending the higher number for less loft decreases bounce. There is more forgiveness factor in having a couple degs more bounce than there is in having a couple degs less bounce on any numbered iron. Distance difference between steel and graphite depends totally on how much weight difference there is between… Read more »

ART My sincere thanks for taking your time to stop by and share your experiences with us. I really do appreciate your interest and your support. I can tell that we’d have a good time chewing the fat about the game and its equipment and I guarantee you that since I just turned 70 last month I certainly can commiserate with your comments about your clubhead speed and distance and assure you that if we ever did have a chance to tee it up we would not mess with the tips and would have much more fun from one of… Read more »

GAVIN You did work with one of the best in Rene. I was very sad to hear that she retired from clubmaking, but she wanted to spend some time hiking around the Alps before she couldn’t so who can argue with that! You never HAVE TO switch from your 771 irons to a 730 set just because you may begin to drop some clubhead speed. The 771’s would still be functional at slower speeds – your distances would certainly drop with a drop in speed and your distance gaps between irons would compress smaller but you could still play them… Read more »

Ralph Many thanks for taking the time to stop by and let us know about your enthusiastic return to the game! Good for you and even better that you chose to stop in to meet and work with Rick. We’ve known Rick for many years in the craft of custom clubfitting and his sincere passion for learning everything about proper fitting and club performance most certainly has built him a long line of very happy golfing customers. From my standpoint as the designer, when I know that someone is working with Rick, I have zero concern that the player won’t… Read more »

DOUG I cannot say what the “big difference” would be that you would find if you changed from the 870s to the 771s, as the clubfitter said. For sure, the fact that I did the body of the 771’s from 8620 carbon steel will make any lie or loft fitting changes far, far, far more easy to do than is ever possible with the 17-4 stainless steel body of the 870s. Back when I did the 870s, the production factory insisted on using 17-4 for the body. They had never made a thin face, press fit installed face piece into… Read more »

Ritchie I start by saying thanks very much for your interest and offering an apology for not having more of our models in left hand. This is one of the challenges in being a small engineering oriented design company without a big consumer marketing campaign. Never in my 35 yrs of designing clubheads have I ever seen a model that sold more than 8% in the left hand version of what it did in the right hand. That’s logical because 6% of American golfers play LH while 15% play LH in Canada, 12% in Sweden. So the net avg is… Read more »

GAVIN You’ll find me from all of my R&D work in club testing to be very critical of ball design and performance based on my findings. I have found that a ball can only affect actual shot performance when the golfer has a driver clubhead speed higher than 90mph, and typically though more like over 100mph from a totally practical standpoint. A golf ball requires a launch speed of over 125mph before any design elements of the ball can begin to influence aerodynamic flight. With a driver it takes a minimum clubhead speed of 85mph to achieve a ball speed… Read more »

GREG Grip size shall always be a personal preference of the individual golfer based strictly on what size feels the most comfortable to the player. While clubmakers can certainly do hand and finger measurements to offer a recommendation for a grip size, in no way is any measurement able to factor in what a grip FEELS like to the user. There are people who measure for a larger size grip who prefer one that is smaller just as there are people who measure for a smaller size grip and love the feel of one that is larger. The only best… Read more »

Phil I complement you on your astute observations of the clubfitting industry these days. That’s pretty well thought out and on target. You only need a handful of insights that only someone who has lived through the growth of the custom fitting side of the golf equipment industry to offer to put it all together to be more clear. And since I started in this side of the industry in the late 70s and am still kicking I can pretty well provide that insight. A big reason for what let’s call the inconsistency in clubfitting is because no one person… Read more »

RON If you just go to this link – https://wishongolf.com/designs/iron-sets/new-771csi/ – you will be able to scroll down a small distance to see the specs chart that has all the specs for loft, lie and everything. If you increase the loft, you obviously would hit each iron higher and a little shorter so the only advantage to doing that would be, 1) if you have a very high clubhead speed to begin with but you have a very downward angle of attack that causes too low of a flight you would hit the ball a more normal height and not… Read more »

If you are a custom clubmaker you are welcome to order through Diamond Golf International who are the owners now of my brand and the sole distributors of all of my product and technical designs. You can contact them through sales@wishongolf.com to set up an account. Thanks very much for your interest,
TOM

Claire Absolutely the 771CSi irons are intended to be a game improvement iron that would be suitable for any player in search of a more forgiving iron that has a higher COR for more ball speed. I would say only players who are very good, lower handicap players with higher than average clubhead speed might want to look to a different iron model than the 771. All other golfers would be just fine when properly fit into this design. 2nd point of advise is to place your trust in Paul for your fitting needs because he does have the experience… Read more »

Raymond Thank you very much for your interest and for taking the time to stop by to ask about the irons. Always happy to help with any information. What you refer to as “heavy headness” has to do with how the clubmaker builds the iron heads into the finished set. It is not a condition built into the heads themselves on their own. Any set that is heavy headed is a condition of FEEL that happens either, 1) because the golfer has always been used to playing low swingweight clubs and just happens to trip across a set made with… Read more »

Frank I have had some talk with Diamond Golf who handle my product line about if there might be a time in the future when they wish me to design a follow up to the 771CSI irons. At this point no decision has been made mainly because the 771’s continue to be one of the very most popular models in my product line. Product line management sort of operates on the basis of “if it ain’t broke, don’t try to fix it” and a lot of the decision about whether an iron is ready to be replaced quite honestly has… Read more »

Christophe Yes, I know Arnaud personally from the many correspondences that he and I have had in which he asks me questions about club design and clubfitting to advance his knowledge. I can tell you that very, very few clubmakers can match Arnaud’s interest and passion to know as much as he possibly can about clubfitting technology. I can verify that he is an excellent clubmaker and clubfitter and that he is one of the best in all of Europe. He will do a very good job of analyzing your swing and providing you with a high quality fitting experience.… Read more »

ERIC Since I can rely on Tim Mosel’s fitting recommendations and fitting analysis being top notch, the way you know if you need to possibly have new fitting specs in a new set of irons is if any of these things have changed for you in the past ten years since the original fitting: a) if your clubhead speed is +5mph higher or -5mph lower than it was at the time of the previous fitting, you need to be re fit; b) if your swing path has changed from out/in to in/out or vice versa, a re fit is in… Read more »
