When in doubt... build hell-for-stout!
Cluster the E16s Maybe, that would be a weak baby G64. Then have an F15 that has less thrust then the E16 push the upper stage of my $600 rocket?
Like the Late Paul Harrell would say, "You Be The Judge"
Have you see the pics and video of Zepher on a G64 fallin' from the rail?
My comments are based on Apogee's specification's.
YMMV (And it's $500 ish)
