I've toyed with using longer shafts in my irons and have found it didn't give me extra distance and may be costing me control of my shots. It got me to thinking that perhaps the 44.5" standard shaft in my Titleist D2 might work better at 44, 43.5 or even 43". Since I don't want to cut the shaft, I may build up the grip on the lower end to allow me to grip down without a change in feel.
Has anyone tried this or found a shorter driver is providing them more distance through an improved "smash factor"?
