Solo diving without sidemount requires either doubles (which are just a pain in the butt), or sidemount. Technically a pony fits some minimum, but having seen how long pony bottles actually last when really needed, I would consider most ponies not really redundant, just bothersome.
Huh? I solo dive with an AL40 all the time. How is it not redundant? It's more then enough bailout gas for any recreational dive.
I also don't see how it's bothersome. I sling mine DIR style and it doesn't cause me any problems at all.
