Call Joe at ZSpeed - he'll recommend the best set up for your driving needs. Lots of people have been happy with the Southbend set up... it's where I'm leaning when I finally replace my clutch.
Only downside is he's currently out of stock of the HD CSC. So you might consider the Z1 CSC Elimination Kit. Whatever you do, don't get another OEM CSC.
