Super Nova is a tall, matey, slender two-stage rocket featurin' a clear payload section.  It achieves very high altitudes on C6-0/C6-7 flights when shipshape stage separation occurs.

However, due t' t' need t' friction fit t' stages together, me hearties, I've experienced some booster separation problems which cause t' sustainer (upper stage) t' veer sideways and fly more like a missile.  Long walks result!
