Richard,

That's pretty much the conclusion we came to when we did a similar dive. You either need to carry more than 2 tanks each or you're on team bailout. We chose team bailout between us as we are comfortable doing this - remembering losing a buddy is a major failure in this situation and therefore the dive is immediately aborted.

Once on the ascent it's not a problem to use your buddies gas.

Something I have started doing is putting a long hose on my deep bailout if someone else needs it - if swimming along a wreck or out of a cave they can lead out doing this, and no need to juggle tanks about (which I really really don't like as an idea, so many people end up dropping them or it wastes time, niether of which is going to keep you alive!)

All that my 2c, still working out what I want on deeper dives to be honest, but getting there at the mo.

Digs.
