Supreme bike set up suggestions required please.

The only thing I kinda of know about suspension so that you want the bike to be working in the middle of the spring under a typical gentle roll on of power - at that's what I took away from Twist of the Wrist II :|

I'm about 15st now and typically have the rear on 2 or 3 down from the stiffest setting. But again, packie makes some very very good points above.
