Answer
Lawny,

A 47" driver may be too difficult to control. Do you have much better control with your three wood. Your three wood should be about 41 to 43". If you answer yes to that question I would recommend shortening the shaft in your Callaway driver. Be careful thogh. If the shaft is cut 2 - 4" it will make the shaft stiffer.

Good luck and let me know how this turns out.
