BIL offers this advice ( doesn't answer your question)Hey Christie, can I borrow your engineering brain for a second? These are the Ben Hogan irons that I have been lusting after. Is the science legitimate?
I am sure those are nice but he needs to get fitted for the best results. Also have him look at Golf Forum - Golf Blog (MyGolfSpy.com) website where they test everything and these irons were tested under the players distance iron. It came in 6th but like I said needs to be fitted.
