10 Degree Loft- Regular Flex. This driver works for me.I like the sound that comes off the face of the club. The carbon metal ones sound muted to me. Would like to get a backup version of this club and try stiff flex. Tried Callaway, Nike, Adams but keep going back to old favorite. The only other club that compared to this one is the Titleist 905 Driver. It might be outdated by todays standard.
