I'm posting a photo of one of my pony bottles. This is an HP13 with stage rigging, a 1st, a button spg, and a 2nd. The first and 2nd are more or less identical to my primary regs.
I have AL19 and HP40s that I sometimes use.
Not sure what practical advantages the integrated setups would have. Maybe if I dove with one I could figure it out.

It's going to shown at the DEMA in Texas. I think that was 2002 or 2003.
A bite valve during an emergency doesn't sound like a good idea. At 6cf, it doesn't sound like much of a buffer. Let's use the amount of gas in 500 psi of an AL80 as the basic starting point: (500/3000)80=13.6cf. This is less than half of that. I dove with a 19 for years, but basic dive and gas planning saw to it that I never ever had to use it. Today, if I'm slinging a bottle, it won't be less than 40cf. Why? It's enough gas for me AND A BUDDY to ascend with a good 5 minute safety stop.
I have done an air share from stupid deep, where the one buddy ran out and the other buddy was almost out. I didn't have a pony, and on our ascent I was sending vibes to the almost OOA buddy that he was NOT going to run out as I was NOT giving up my necklaced reg. This was a rescue and both of them were horribly bent. The last I heard, they never dove after that incident. Buddies tend to run out of air together. If one buddy is checking their air, they usually prompt the other buddy to do the same. So, if one runs out, the other is probably almost out.
For the record, and it's as much as I'll publish on the interwebs, I was not a part of their dive team, nor were they a part of my class. I share the story only with my students as a study in the power of narcosis combined with the stupidity of an instructor.
Nice setup! Thanks for the pic.This is my sling setup for a 13cf. I also sling a 6cf the same way and bought one of Wookie's that comes in a bag with clips ready to sling. It's also 6cf. BTW - Wookies has a breakaway strap that releases the bottle and has a regular octo. Highly recommended - can't beat the price.

13 cu-ft may not be completely useless, but it's so limited, I just can't see myself ever choosing to sling a 13 when I can sling a 30 or 40

I agree with the others...6 or even 13cf is way too small for most average divers ... I wouldn't consider such a small tank as my back-up.
I [...] decided a 19 was a good size to carry and was larger than my bare requirement. I never surfaced from a dive wishing I had less air my advice is to go bigger than you need rather than hope your 9cf is enough.
Do the math and figure that you were doing your normal 100' dive when you got caught in a down current that shoved you to 150' before you got out of it now is that little tank going to get you to the surface?
Anyone care to run the numbers on that accent?
I like that valveulator or reguvalve or whatever it is. Got a name or a link by chance?This is my sling setup for a 13cf.

My thought is simply that there are easy-to-imagine scenarios where you would really want a 30 or 40. In which case, why not just buy one and be done?
I note that nobody has said anything about having to do a bottom swim before starting the ascent. It's all well and good to only need 8 cu-ft to get to the surface, but a lot of my dives would first require getting back to an anchor line before starting the ascent.
