I was fitted for 910D2 driver and 910F (17 degree) fairway - both shafts were Project X. The driver shaft feels outstanding but the Project X in my 4 wood feels stiff as a board. I was playing 909F's (15.5 and 18.5) with Grafalloy Pro Lauch Blue shafts (stiff) that felt great. Does Titleist offer a fairway wood shaft for the 910F comparable to the Pro Launch Blue (even the upcharge shafts)? I really want to only carry the 4 wood in my bag.
