  1. Hi Tom. Wich hcp group Do you recommend for This Iron ? Cheers Mike

    • MIKE

      Sure thing happy to – 1) any golfer who wants more distance with the irons due to either not having a super high clubhead speed to begin with or because they are losing swing speed either from age or injury; 2) any golfer who could use some more distance but a high priority is to get the most distance possible when they do hit the ball off center. If I had to put a basic handicap range on the model, I would say 12 and up, but that’s not really the biggest thing to qualify the model for golfers – the desire for distance and off center hit forgiveness are the bigger two qualifiers.

      We don’t tend to see this model as being for the low single digit handicapper unless that player is losing clubhead speed for some reason. Although we’re hearing that more golfers who do play serious tournaments have decided to play this iron.

      Another big part of this iron is the fact that it offers more distance from its high COR face design and not from lowering the lofts more and more, as has been such a trend for game improvement iron designs from companies over the past 15+ yrs. For all golfers, you do get to a point where the loft gets too low for their ability to get the ball well up high to fly. But with a high COR face, we can keep the 5 iron loft for example at 26* and not have to shove it down to 23-24* which is what several of the companies are doing to try to offer more distance to golfers with the irons. Do that low of a loft range in sets and for many golfers, you make it so they can’t possibly hit the 3, 4, 5 and sometimes even the 6 iron, so they end up wasting a bunch of money in buying such a set.

  2. What is the cost of this high COR iron set?

    • TIM:

      All of the custom clubmakers are independent so the final retail price of any of our designs when custom fit and built for golfers is determined by the custom clubmaker who does the work. However you will find that the vast majority of clubfitters do the fitting and the custom building for a price that is commensurate with the retail price of any of the major brand models as sold through any of the big golf retail stores. The 771’s are a more expensive model because they are a high COR design with a soft carbon steel body. I recommend you click on the FIND A CLUBFITTER locator found in the center of our home page on to find a clubfitter in your area, then call him and inquire about his services and pricing. If you need any help in finding a clubfitter, please do not hesitate to contact us to ask for assistance.

      Thanks much!
