Well thanks guys----My dive buddys all think I'm insane. Dove with the air 2 today. And the octi still on my rig. I figure I'll do a couple of dives before chopping the octi hose off.
I think I've mentioned this before on this thread, but don't chop it off - move the octo to a pony bottle and dive that way. I do, so does my wife (upside down pony in yellow next to the 100's tank boot in black). Two birds with one stone....
BTW, no scuba police have said that you can't use your Air2 as your primary - it is after all a perfectly good functional reg that I bet my life on...(talk about opening a can of worms!)
