I'm another fan of the backplate/wing BC's. I started with a SeaQuest Quick Draw jacket BC which was a nightmare. Next was a Zeagle Concept which I loved. You could get different modules for a better fit, ie. small shoulders, large waist, etc. But it wasn't until I tried a BP/wing that I got a truly custom fit. I have a FredT alum BP and Deep outdoors 30#wing, a DiveRite Deluxe harness. It fits like a glove for less cost than a 'regular' BC.
I've recently lost about 60#. In a regular BC, that would have meant buying a new one. As it is, I've adjusted the shoulder and waist webbing to keep that custom fit. Another plus for the BP/wing set-up is I can add the kind of pockets and integrated weight system I like, not take what someone else decided I would use.
Another plus is after you've been diving awhile, your tastes and needs will change. This usually leads to folks having to totally replace their BC. If you're using a BP/wing, you just add or subtract D-rings, pockets, etc. to address your current needs. You do NOT have to be a 'technical' diver in order to use a BP/wing.
