I run an xcelorin 5.5 turn setup, and that's fast enough for pretty much anyone's needs, I think. If you're running lipo, a 6.5 turn combo would do well, and probably cheaper to pick up that way. Several people run an xcelorin setup at the club and are happy with it, and it saves you a shedload of cash over the comparable-performance alternatives. Parts-wise, DMS are top notch for associated bits.
