Then there's the corollary to this discussion: the integrated second stage. Once you choose your desired hose length, you'll find that you have a challenge breathing from the same second stage that you're using to control your buoyancy as you ascend with a panicked diver, whose own buoyancy you may also have to control. Very hard to do smoothly at a moment when you need to be at your best. You run out of hands if you need to take the reg out of your mouth to elevate the corrugated hose to vent, at the same time as you're nearing the surface.
I was seduced by the same thing 35 years ago. Dove it successfully for many years. But when I became an instructor, I finally realized the flaws in the system and switched over to the necklaced octo that I still use today.
I realize your frustration. The local dive shop model is broken. The advice you're getting is conflicting. You've plunked down some money, and the possibility that you've made a few errors maybe makes you a little angry.
Hang in there. It's a great hobby/passion/job. But ponder some of the advice here. Meanwhile, don't sell your integrated second. I put one on a Scubapro Go lightweight bcd for a trip to Bonaire a few years back because it was so compact and light in my baggage. It has uses!
I'm not sure I am able to understand the added complexity that you seem to be attributing to the Air 2. Generally the Air 2 was offered with a BC which had an independent pull dump, so venting was independent of breathing.
However, if a person places an Air 2 on a BP/W which does not have an independent shoulder dump (only has an elbow), then if ascending vertically, they could grab the Air 2, hold it up and press the deflate button for a second or two, presumably while they are exhaling.
If someone were in the exact same situation with a standard BC inflator, they would have to grab the inflator, hold it up and press the deflate button. Which is the EXACT SAME action which is required with an Air 2? In fact, if you think about it, in an emergency, a diver might have some challenge locating the standard BC deflate mechanism. The Air 2 might be "better" because with an Air 2 shoved in their mouth, there is absolutely no problem with locating it -since you are holding it with your teeth. I see no difference or any need for a third hand.
Of course, the diver can not be simultaneously inhaling from the Air 2 while it is held above the head and being vented, but this is a duration of 2-3 seconds, and generally when I am trying to decrease buoyancy (or slow my ascent) I am going to be exhaling anyway.
Can you clarify where the "third hand" comes into play with the Air 2?
