Titleist tips Tour AD DI shafts 1/2 for standard installation. I am having a custom shaft built at 44" playing length, for a 6SR Tour AD DI. I am not looking to play Stiff as with a 6, but would like to stiffen up a 6SR a bit, would it be wrong to have a Tour AD DI tipped 3/4 of an inch or full inch? Would an ammiature player feel the difference?
