Currently playing 913 D2 with Titleist Bassara W50 Reg. flex. Club head speed is 90-93, love the feel and flight of the ball. Currently, hitting it about 215 carry, my question is would a Graphite Design BB 5 regular shaft give me any more distance. None of the fitters have exotic shafts in regular flex.. Any suggestions for more distance other than lessons or going to Acushnet Ma.
