I was recently shaft fitted and found out that the Steelfiber  i70 s and i80s worked best for me. My club speed increased about 7 mph from 77 mph to 84 mph, with the i 95 r I gained about  4 mph to 81. I would like to know how the Aldia VS proto 75 and 85 r and s shaft plays? I have heard that Aldila shafts tend to play stiffer than most other graphite shifts. I plan on getting AP2 irons and the only light shafts Titleist will install are the VS Proto 75, 85 and steelfiber i95.
