Right now, I use the Taylormade 07 Burner in the stock regular flex shaft. A while back, I picked up a barely- used Callaway FT-i I-MIX driver with a Grafalloy ProLaunch Platinum stiff shaft for $75 at Golf Galaxy just cause it was a good deal. I could never really hit the Callaway and was happy with my Burner, so I decided to try and sell it. My first attempt at selling the Callaway flopped, so I took it to the range the other day just to see if I could hit it now( I have made some drastic changes to my driver swing), and it turns out I can hit it ok now. I really like the stiff shaft, but I'm not so sure about the head and vice versa with my Burner. Do you think I should sell or trade in the Callaway and look into a brand new driver? Or should I just try and get used to the Callaway head?
Or
should I look into reshafting my Burner with a good stiff shaft and get rid of the FT-i? I have no clue what to do and any advice would be appreciated.
P.S. My swing speed is in the stiff flex range and my irons are stiff.
