I have been searching for a 913D2 with a 10.5 head with the Bassara Stiff flex shaft . My local pro shop only has the 9.5 head with that shaft. There telling me you can change the loft by messing with the configuration of the sure fit but my question is if that is the case without changing spin why do you offer it in the different lofts? TM's new driver loft isn't even a option but yours is. I have extremly low ball flight and just want to make sure I get right set up before I spend $400.00 on a new driver.
