Best Air Mix for Pony Bottle

[northernone]

My take on emergency gas supply is I want the most versatile gas I can carry.

That's air for practical purposes.

A downwelling is one of the logically possible reasons for running out of gas, I'd want extra gas I am comfortable breathing deep as well as shallow. Same goes for going down after a sinking diver.

Accelerated deco isn't my main concern. A little bigger bottle feels better to me covering both emergency deco and unexpected time at depth.

All this talk about mixes! I would take a breath of pure O2 at depth in an emergency ascent if it were the only thing I had left. How long do you plan to breathe off that thing?

I'm in agreement, I'd just rather have one less thing to worry about on the way up.

This seems like a good time for DandyDon to chime in with the donkey line.

First, you must travel to Nepal in the spring, but you must do so after the most perilous phase of the avalanche danger no longer threatens your passage through the steepest clefts of the Alps, those that lead to the hidden mountain meadows of lore. Then and there, not too high, and not too low, but just where the eidelweiss will eventually bloom, and only in the two days (no more, no less) before they are in full flower, you must find the High Priest of Compressordom in the cave at the Northeast corner of the Meadow of Wisdom to fill your pony bottle with the rarefied Essence of the Alps, which will have the perfect balance among the scented essences of the meadow, O2, and N2. It will protect you against all evils. You will have to take a boat back, of course, because airport security won't let you take a full tank on the airplane. Unless, of course, you happen to be diving in Nepal.

Alternatively, you can simply put air in your pony, stay within the NDL, keep an eye on your SPG, and use the pony if an emergency develops.

One of these is a lot simpler than the other...which is a long way of saying "don't overthink this." Get it rigged comfortably and make sure you can deploy it reliably. Extra points if you can quickly hand it off to someone else, which could be important someday if they are on the edge of panic.

(It's been a long week. Sometimes my sense of humor gets the better of me. Hope you're not offended!)

If only you hadn't transplanted the Alps into the Himalayas (Nepal), that definitely would have been a big time like. So, now just a small time, verbally expressed like...
But apparently there is some sort of other kind of Edelweiss in the Himalaya.
Edelweiss in the himalaya? - Google Search:
So, now to achieve all you said, I think it is necessary to create some sort of essence of Edelweiss (either one) and get that mixed into the gas. Either Edelweiss will do as at 3000 PSI you cannot tell the difference. That is going to be tricky so, as at least the Alpine variant is just about the most protected thing in the Alps.But if you manage, your depth gage will now display your new MOD in feet on its scale. And, ...
Ahh, come on, please stop reading... or I could stop writing...

-you sure that wasn't a Bob Bailey quote?

Edit for accuracy:
Nitrox to an OOA Diver?

Could be. There were so many back then.
Ah, I found it.

Frankly, I'd suck a fart out of a donkey's ass if that's what it took to make it to the surface alive ...
