But maybe you have something more constructive to say PfcAJ ? Maybe a reason why sidemount wouldn't work for the courses I'm wanting to do? I'm all ears out to listen, I'm genuinely looking to understand why those instructors don't give me a reason for not allowing sidemount to a course down to 40m.
What you're seeing is some dude swim around with a bunch of tanks. Any dip**** can do that. But can you switch gases efficiently? Can you see your MOD on those tanks? Can you drop them and pick them up quickly? Can you stow used hoses easily? Looks to me like that guy is playing dress-up to impress the sidemount myrmidons. Let's be real, the guy doesn't even have enough regs to put on those tanks. Its theater.
Here's a think: Lose a reg (esp a 2nd stage diaphragm or hose failure) and suddenly you've lost half your gas. With BM, you still can get at all of it. That's significant, in my mind. In a few posts, you'll get the 'feather the valve' people chiming in, followed by the 'swap regs underwater' group. 99% of them have never had to do such a thing for real outside of class or some pre-arranged practice scenario where their bailout scenario might as well be "switch to snorkel".
Almost anything works in a sterile environment, and highly seasoned divers can draw on their experience to get themselves out of dodge. Most divers are not diving in a swimming pool, nor are they highly experienced. KISS.
