Here is a backwing setup I put together with a set of twin fifty cubic foot steel tanks and a stainless backplate. I used the Apeks WTX harness with the d45 wing / bladder. It is very nice in the water in that it hugs the back and feels very balanced and more compact to you body than a single tank. I have DIN valves installed and use a Poseidon Cyklon 5000 metal on one valve and a Scubapro mark 2 on the other valve with the inflator hose for the WTX and a pressure gauge. I do not have this setup for redundant air just comfort in the water and a little bit larger air capacity. I really enjoy it.
