I dive with an OMS IQ PAK,STA, 45lb wing, SS back plate, but opted for the DUI weight harness. I'm very happy with this set up and it works well for me. I looked at Dive Rite, there were certain things I just didn't care for. As far as Halycon gear, it's too expensive and over rated and I don't agree with all of the DIR commandments, so why support it by buying their equipment.
