glad you made it across mate!
haven't done any of that yet - but I did get some SS springs and a Paulimoto spyder retainer plate to replace the individual caps. Apparently evens out clutch pull (mine is very late catching apparently). You'd have to decide on the PP before though.
have you gone to Desmo times to check out his (Mr. Snyder) clutch section...
one thing I've noticed - the billet PP don't seem to save very much weight - but they look great!
