I switch around. It doesn't seem to matter much. When I play Torrey Pines north, hard greens and hard to stop a ball on, I'll try to play a urethane ball like a pro v1 or Taylormade tp5, or better yet, a Taylormade project a. But for most courses something like a Supersoft is just fine.
Not sure it makes sense to play the same ball that the pros play, given that I have a slower swing speed. Could the same ball come off a driver with a 1.5 smash factor for both a 120 mph swing speed and a 90 mph swing speed?
Has got to be Srixon for me. My putter and wedges are Cleveland and my Irons / Utility Iron are already Srixon. Since both are owned by SRI Sports Limited I'm counting it...<_<. So the only thing I'd have to replace would be my Callaway Driver and my Taylormade 3 wood.
Ping or Titleist, MAYBE Taylormade would be the only clubs I could see putting in across the bag, even though I've never owned a Ping club, and only one Titleist hybrid. I love Mizuno/Bridgestone/Srixon forged irons and wedges, just have no interest in their woods (not enough advertising hype?) and any putters they do make seem more like afterthoughts.
