'Much' is a relative term, I think I131 in wood carbon with a proper fin would be an ultimate light wind
machine for 8.5 sail, I121 would still work well comparing to hypersonic, cleaner bottom with sharper rail
will create better release to plain yearly. That deep double in hypersonic made it sticky to be an early plainer...
