I am considering switching from regular to stiff shafts and was wondering what swing speed is desirable for stiff shafts. I think i am in between flexes with a 95 mph swing speed. I know that shaft flex straightens out balls flights that are a bit erratic. For example I know that when png first came on the market they sold their clubs with X flex shafts. Of course, they didnt tell anybody or put it on the shaft but people hit them straighter, shorter, but straighter. I was wondering if a switch wil be for the better or play regular flex for as long as possible.
