I ran a quick sim of the B7 as the first stage booster in an Astron Farside, and it looks to be sufficient, at about 43fps on a 3' rod. Even the A7 should work, at 39fps, staging at 18'! A B7-A7-1/2A4 combo puts it at 580', staging at 64 & 141 ft. Here's a vote for the hybrids, so we can fly our small 3 stagers again!
