https://www.titleist.com/teamtitleist/team-titleist/f/club-fitting/19157/909h-and-ust-proforce-v2 Hello- I'd like to install a UST Proforce V2 Hybrid shaft in my trusty 909H 19 degree hybrid. Since the shaft diameter is .355, do you shim a .335 or bore the hosel to accept a .370? Thanks, Mark C en-USTelligent Community 10
