Nothing like firsthand experience...

I wasn't on an 80--I avoid diving on al 80s as much as possible. I was diving a single 120. My tanks are HP 130s, but I was using rental 120s that day. And as I mentioned, I'm already looking at getting a doubles setup soon, for the redundancy.

I just want to pont out that when diving solo, you should have seperate redundants. I have a lift bag that is my redundant lift for my bc and I have a pony or bailout bottle that is adequate to get me to the surface from the depth I am at on that dive. Using doubles is not redundant air. It is a lot more air, but not a redundant system. Please think of that.

Zen, asking in all seriousness, aren't independent doubles considered redundant?
