I am using the 32# OMS wing with a SS BP and STA with the single weave harness. I also use the OMS aluminum BP with the "deluxe" harness (it has a quick release on the left shoulder, I guess that makes it a "deluxe"). I only have a little over fifty dives on the wing and aluminum back plate, fewer using the stainless steel as I use it with the dry suit. Niether bps or the wing have been a problem. If it were, or there was a mechanical problem, I feel positive that the dive shop that highly recommended and sold the gear would back it up.
