Thanks for all replies!

RapRap,

I still haven't decided if I want/need to got with a power booster yet, but I'm starting to lean farther toward the piggy-back MC setup. I didn't realize there was anyone making a bolt-on MC and not have to cut a new hole or go with a remote fill. Do you have pictures of your setup?

Was there anything tricky about getting the clutch setup with your arrangement?
