Oh the choices....
I guess you have at least the following
Bucci road/track
STM 48T
Ducati Corse
JHP/Sigma.... etc etc
Pros/Cons from my point of view
Bucci (Pros) - You can use your existing plates. plenty of spares and easy to maintain. (Cons) - Bearings supposedly need regreasing every 1000 miles (dunno if that is strictly fact or not), due to being a 12 tooth basket that'll wear quicker than the STM.
STM (pros) - Plates should last longer as there are 48 points of contact (Cons) clutch plates are more expensive as specific to the clutch, and you need a specific (expensive) tool to remove the pressure plate, if you were to do a foreign trip, or track day abroad and your clutch went could you find a set of plates?
Ducati Corse (pros) - probably the best action of the lot, I would imagine will take more HP than the others being a full race item (cons) - spares?
JHP/Sigma (pros) - cheaper? but pretty much identical to the standard 12 Tooth baskets etc (cons) - same as above.
