But if you are planning to dive alpinist-style in the cave, then I have no comment...

Absolutely not. You know me better than that Phi! Alpinist in a cave is a nice quick way to stay in the cave!
I don't have "spare" dil and O2, I have the same as anyone else, standard inboard O2 and dil and offboard bailout configuration. I am more fussy about the placement of connectors and hoses though.
Look back through earlier posts in the thread, I plan for worst case scenario possible and have enough OC gas to exit off the loop.
