I'm currently using a Mejzlik 22-8. I would have used a Menz in the same size but the nose was light enough already. Normally I would have used an MSC 22-8, but the weight of the Ultimate (light!) and the additional drag of the second wing pushed me more towards speed over thrust. The choice worked out really well. It's not fast unless you want it to be and pulls vertical out a hover, as some would say, "with authority".
