I need some advice regarding graphite shafts in the AP1 714 irons. I'm considering putting graphite shafts in my New AP1 714 irons because i feel the XP 95 are a bit heavy compared to my old clubs with KBS 90. Wondering if the UST Proforce Rv2 75 Gold is an option. I don't know what TIP type and size this Titleist iron has and if the USTs will fit?
