How glad I looked at this thread. I remembered I have an AL ABS that I have barely touched. I HATE it - BUT it has a 40" hose on it that I just needed and didn't have. Yeah!
I totally forgot I had the reg because it was force-sold to me when I started diving, and I only used it briefly because I thought it sucked. (Anyone who loves it, gimme $20 an it's yours - without the hose!) I am sure mine is tuned sucky but it's also the shape that I find awkward in mouth, and whatever is said about Egress being better, I would still always opt for another XTX or Legend octo myself.
