I play a 910F with a Bassara 55 A-flex for a slow swing speed (recommended by a Titleist Advanced Fitter). It's good but sometimes feels a tad soft and light (even though I like a responsive tip). Better to go with a Bassara R-flex, or the RIP Phenom 50 R-flex? I realize that only a fitter can truly tell, but I'm curious whether anyone has tried the Phenom 50 in a fairway wood.
