| I've never understood the point of an O/C reg permanantly attached to the O2 side of a rebreather with only a 2 or 3L cylinder. If the reg freeflows you are in the shit, think about the O2 pressure you surface from a deco dive with, now work out how long that gives you at 6m. Not long enough. if you really need O2 bailout take a stage.
surely you have enough clutter on your front with the air2, 2 handsets & 2 counterlungs, why add another 2nd stage for very little return. rather than add another reg, I'd ditch the air2, if you haven't already done so.
