I had the stiff Mid Kick Mitsubishi Nike Stock Shaft in my Nike SQ but it seemed to be really whippy, so had a stiff Mid Kick Proforce V2 shaft put in and now I hit this unbelievable hook. I can definitely tell the Proforce V2 is stiffer than the Stock Shaft but I'm wondering if it is too stiff. Anyway what I need to know is a shaft that is too stiff for my swing speed will that promote a major hook??
