Daggs method is the correct one. However, I do it like you do Blk91 - not because I am worried about too much preload (you can still feel when the diaphram fingers start to load up), but because I dont want the TOB meshed with the PP fingers constantly. When the TOB starts making noise, I will tighten it up to quiet it up, till I fix it.
I think most hydraulic clutch set-ups feel like poop. They bite just fine but dont give good feedback as engagement take-up occurs. (it is like shifting a cable operated clutch with a leg that is half-asleep).
A really smooth cable is just as good as a hyraulic set up, IMHO.
