As for alternatives, there are some nice self-pressurizing, non-lethally
toxic propellant combinations (if you want to roll biprop) like
Nitrous/Ethane, Nitrous/Propylene, etc. I know that nitrous is
definitely not a walk in the park either (Most of my work has been with
the stuff, so I may be a little biased there) and that peroxide offers a
significant density advantage, but you lose a large amount of complexity
that you'd have with a pressure-regulated system. It is of course a bit
more boring though.
