Hi all, This is my first post so go easy on me. I have a 910D2 with a Vertigo Doom shaft (yes its bespoke Finnish item that you have probably never heard of but its good) 68g, torque 2.8 and my SS is 102-105. And now the snow has melted, I am, just as a treat, buying a 913D2 and my first thought was to just get a light stock shaft - switch shafts and on gift the 910D2 to my son. But then I started pondering shafts and what others with similar swing speeds and handicaps (12) have done on the custom shaft front with their 913s. Yes I know each to their own and get fitted (which I will do with my great local store here in Helsinki) - but still very curious as to what combos people swear by in the real world. It is great that Titleist offers so many upgrade options but it is a little daunting for a tech-novice (and yes I trust my fitter bloke but he does have very strong opinions on brands etc so need to be informed to discuss with him). My internet research has thrown up a few repeat names: Fubuki K series, Kai'li, Tour AD BB6 & DI6, Oban Devotion 6 - interested in the performance gap/advance over the stock shafts. Money is not a big issue if its value for money so to speak, but not interested in paying for pretty graphics or a name. Any and all assistance greatly appreciated. Regards Karl
