What is the proper procedure for using stages? Should one breathe off the stage first so that ample back gas remains in the event of an emergency (makes the most sense to me)? or Should stage bottles be, uh, "staged" for the end of the dive so that additional bouancy is available in the the event of an emergency (empty back tanks)?
What about caves or wrecks? Should bottles be used on penetration and exit, just exit, or just penitration? All three seem to have their own advantages and disadvantages, so I am sure they have their specific purpose.
