I use an AL30 slung on the left with I think a 26" octo hose and naked spg on 6" hose, as others have suggested. More than enough to safely terminate any dive with a safety stop in rec limits, which is where it's used. Hardly notice it in the water. I don't use it when I have a buddy.
But after reading your follow-up posts, I think better gas management/awareness or a more conservative dive plan would be more beneficial to you and your dive buddies than the pony. A pony should not be factored in to your dive plans, whether it's "extra time underwater" or "added security to others."
my dive plan doesn't require it.. nor do we make plans to run out of air and need a pony .. it's a backup.
Im just looking for ideas what size a back up would be and how it should be carried.
