I never said this particular propellant combination is particularly great for
density although I can understand it reading that way - apologies for any
clumsiness with my wording. What I meant was strictly that density ISP will
likely be of more importance for this particular application than ISP.
I strongly disagree with your last sentence. Have you seen the formation energy
of acetylene? It's in a whole different league to that of HTP or N2O or
Hydrazine!

It's probably a bit simplistic to gauge the performance of a propellant by
the elemental species it's comprised of, and for this particular case, the
density ISP is likely of more interest than the specific impulse itself
anyway. Remember, there's a considerable portion of energy contained within
the bonds of the 2 primary ingredients so you're obtaining energy from both
the dissociation of these compounds AND the subsequent O+F reactions of the
free radicals produced from the decomposition (the more typical source of
energy from rocket propellants).
