I recently visited the PGA Super Store in AZ. I learned that my stiff driver for my 910 is (72 gms) is no longer suitable for me. It appears that a tested lighter shaft and regular flex could perform as well as buying a new club. My club head speed is 90 and my ball speed is 130. The golf store "advised" me that a new shaft is throwing good money after bad because my driver head is technologically behind. Please advise.
Thanks
