If you're diving a single RB, there is no point thinking about "thirds" or any other similar margin, as Stuart says. If you are going a long way, and deep (which to my simple mind is the main reason I might get into RBs), then it seems to me the only way to go is two rebreathers. Plenty of gas with variable O2 setpoint for deco, but probably some OC deco bailout for comfort factor (I always was a scaredy cat).

It's always a comfort to know you have enough bailout and staged gas along the way. Sometimes deep into the cave (solo), when it's just tunnel after tunnel after boring tunnel you can get carried away with thoughts of "what if". That's when it's a comfort to know that OC gas is along the way. Funny on the how mind works when it has the leisure to freely roam.
