I was thinking I would be fit in senior flex graf. But not to be after a two hr fitting out doors. With trackman have steel r flex black shafts I have nothing but good to say about fitting and ap3s(had ap1s 716s).the wedges were fit according to gaps in degrees to other clubs. We must have tried ten to fifteen different shaft head combos to fitt the set up best for me the game I play.oh yea shot 80 on whites so cool!
