What is the swing weight of the 915 fairway woods? I'm playing the 915 F with Aldila Rogue Black Stiff Shaft. Fighting a hook with this club only despite having the same shaft in 915 D2 and 915 Hybrids all set to A-1 and no issues with ball flight or trajectory (baby draw with all). Wondering whether it would be worth changing the adjustable weights before trying another shaft. Thanks.
