Todd (hyprduc) & I have the DP Corsa slipper clutch, which is a straight forward proven ball & ramp design, really simple actually, the clutch comes complete with basket & everything else minus the plates, the good thing about this slipper is that it uses stock or stock style 12T tab clutch plates, which are waaaay cheaper than the 48T plates that some of the other slippers use, I'm now using Barnetts plates, cost about $160.00 The other good thing about this clutch is since its a DP item you can get replacement parts for it at your local Ducati shop.
Look for this clutch on Ebay, sometimes at a "really" good price!
