B.C. Choices

I did purchase a very used Aqualung backpack with twin 63's mounted to it. I primarily bought it to use the manifold and screw two 80's on it. I tried to hydro the old 63's and the LDS told me that they may or may not pass. I chose not to hydro them and I sold them on craig's list and made 25 bucks... Just another reason not to buy those good deals on-line. It was a lame idea for me to even think that it would be a realiable set-up. It was so old that it had a J-valve that when the one tank was done you would just reach back on the lower left side and turn on the other tank. Not the redundancy of the twin tanks, twin first stages, and the twin second stages. There are strong advantages for diving with twins if done correctly and that would be the determining factor of me buying a back-plate with wing.
