Default Sentunel Margine of Stability

The second stage alone has a margin of 1.31 in your design. What woul be the min accectable margin for the two stage version? Your 2 stage version has a margin of 2.76
but the fins are very unsymmetric compared with the the first stage. I have modified your booster design to a more symmetrical look, but the margin is only 1.18. The margin can be increased slightly by lengthening the booster from 3 to 3.5 inches.
