I'm just back from a week of dive vacation in Okinawa, Japan with my new Brigade BC, and it was excellent!! I'm 5' 8" tall and the SM size fits me perfect. Although I dove with just 2mm one-piece wetsuit and the BC doesn't have thick cussion at lumber, the tank always kept on my back firmly and comfortably. The only but tiny concern I had was a relief valve at the left shoulder, which is a bit too such sensitive that even a small pull of the inflator hose dumps the internal air. But it's a good thing at the same time meaning it's so easy to dump the air.
One time I had a chance I need to wait at surface for boat coming from distance, and it was true the back inflator BC is a bit difficult to float at surface in comparison with jacket styled BCs, but it still pushes my upper body high enough once inflated, I felt.
My picture with Brigade is here.
