DonM but I've been playing my irons 1/2" long this summer, with 7i at 37.5". And I am going to add another 3/4" based on a test I did.
I played the past 2 days with my Rogue irons, after reshafting them at +1", and with soft-stepped S flex, instead of R. I never had the opportunity to hit many irons either day, but I can say, I've never hit an AW that far in my life. I do need to get the lie angles flattened, then they should be just that much better for me. My W-F is 33. I've been playing long drivers, 46-47.5" the past few years; I've even experimented with longer FW clubs, and hybrids, but they do have to have the lie angle that will accommodate such. Very few do. Us old, weak, short guys, do what we gotta do. 😁
