You will have to do things differently in an emergency? Ahhhhhhhhh..... Yep, errrrr, you might have to find another source of air, just a suggestion.... I might also try to find another way to dump air on my BCD other than hold the LP inflator over my head (like using the 3 other to dump air).
To say that In an emergency 99.99% of divers will remember this that or the other thing is the only way to save there lives doesn't really support the argument. for most of my diving career (Certified in 1980) my octo was tucked neatly in my ass crack. For most recreational divers, there octo might as well be stored there. I grab my LP inflator several times every dive. I think that trumps the fact that most divers are practicing air sharing with their traditional octo, how many time during a diver? How many times on a dive are they checking where your octo is located? The benefit of muscle memory from grabbing and operating your Air II will go more for situational awareness than the diver that OCCASIONALLY checks where his secondary is an if it is hasn't slipped out.
Air II may not constitute a majority, but there are probably more of them out there than there are people with DIR or HOG configurations. Not that there is anything wrong with diving those rigs, despite the fact that make only a small fraction recreational divers. Although, we might consider banning all those rigs with there confusing piles of redundant gear, it might confuse a stressed diver, preventing them from successfully mugging other divers for there back-up air, causing more gear related tragedies.
By the way, who exactly does "We" represent? Writing yourself in third person plural does not constitute a knowledgable majority.
What exactly are you guys reading? Because few of you are responding to what I wrote. "To say that In an emergency 99.99% of divers will remember this that or the other thing is the only way to save there lives doesn't really support the argument." The only way to save their lives? I said that I believe one way is statistically safer than another. That's all I said.
"Writing yourself in third person plural does not constitute a knowledgable majority." Where did I say or imply, even obliquely, that we were a knowledgeable majority? I was simply including the other people in the thread that agreed with me.
Please feel free to disagree with me, I enjoy chatting about diving. But you don't need to make stuff up out of thin air. I say enough actually dumb things that it isn't necessary.
