Curious about the 18º 915Fd listed as JT's 5 wood in several "what's in the bag," posts on various websites. The only 18º Fd I'm aware of is the 913Fd that Webb Simpson also games. Great club, the Senior Citizen 3 Wood for me, long off the tee, launches fairly high and rolls out nicely.
Or is his a prototype? I wanted to try one and bought a well used head that looked like it was in a paint mixer full of steel wool. But after work with 2000 grit sandpaper and rubbing compound, it looks decent if not new.
