I think it's what NAUI calls an ESA (swim to surface with no air).Not to sound dumb but what is a CESA?
What is SD?

Here's my problem with pony bottles. If diving a pony bottle, it is not going to be my donate bottle because I donate out of my mouth. This means that my long hose is still on my backgas bottle and then the pony is the secondary on a suicide strap. Very annoying to deal with due to hose routing and you can't just pass it over to someone. Alternatively you can dive a normal reg configuration on your backgas and have the pony as something you can hand over, but now you need to donate normally, then get the OOA guy to switch bottles which is easier said than done. Means you now have to switch regulators which can get interesting depending on the situation. Not to say it can't be done, but probably more of a PITA than necessary.
If you are diving deep enough that you need a large pony, I.e. 100ft, then I believe you should be diving doubles or sidemount anyway, and if you are carrying a sufficiently sized pony, I.e. minimum of 30cf for 100ft depth, then a set of double 80's or 72's isn't that much heavier or annoying.
Any shallower than that, i.e. 60 ish ft, just do a CESA if you are dumb enough to run completely out of air or unlucky enough to have a total loss of gas, AND not be close to your buddy. Either of which are your fault for not having proper buddy diving technique.
You are probably right!I think you worry too much. My 1st deep dive was in Cayman Brac, dive site called Son of Rock Monster, 126', on July 2005, dive log # 15. My more experienced dive buddy was with me, closely watching me. I felt like diving in 30' deep.
