I see a lot of posts advising people to never dip into their pony gas because they decide to extend a dive longer than their main gas allows them.
I've been doing a lot of dives where I carry a stage bottle that serves as my pony, but it contains more gas than needed to get me back to safety in case my main gas source fails. For example, A dive that would call for a 13cf pony, but I carry a 40cf bottle and plan to use the top 1500 psi, and reserve the bottom 1500psi for emergencies. Or better yet, I carry an 80cf stage bottle, and reserve the bottom 1000 for an emergency, but plan to breathe 2000 of it during the dive. In these scenarios I always make sure that neither gas source gets below the amount I need to exit if the other fails.
Are there any problems with this setup? Is this basically similar to using independant doubles? Or is it dangerous in some way that I haven't thought of?
