I know this thread is from last year but came across it today. Im a beginner golfer, started two months ago. I went to Golfsmith to get fitted and they said i need a stiff flex driver. So i said ok.... ill take the Callaway RAZR FIT in stiff flex. After a few rounds of golf i had my first lesson today and the golf pro asked me why i bought a Regular flex and that i need a Stiff. Golfsmith fitted me for a stiff flex but gave me a regular flex and my dumb ass walked out without checking. Im going back tomorrow to see what they can do for me. Hope they are able to correct the problem.
