I have not decided on which shaft I'm going with yet (314^2 ob1 or tiger) but I do know I would like to try a little smaller diameter in shaft. I am either going 12.50 or 12.25. Would you even be able to tell a difference between the two. I have played alot with 12.75 and 11.75 but never anything in between. 12.75 feels too big to me and 11.75 is a little to small plus it punishes me when my stroke is a little off. What do you think?
