I just got the Eclipse system for my wife today at ID (and some other halcyon toys). That said, I have been diving a bp/wing for 3+ years now (H Pioneer for singles, and now an evolve for doubles). I would never...ever go back to a "standard" bcd--it was the best move I ever made. DSS is very similar in design (as I am sure you already know) and after getting a few dives in you will find it easier to don/doff than "normal" bcds.
