Thats funny, I have trouble going from a full susp bike to a hardtail.. but other than having to go slower on the downhills and some occasional leakage and bruising I've never had any major problems with the transition.

My best advice would be to let the suspension do the work as long as you balance your weight correctly its amazing what a good suspension can soak up. Make sure to set up the pressures for your weight and then get into the compression/rebound dampening.
