The Twist and the Magic are both good choices. The magic would be a better 3D plane, the Twist being a better overall performer. Another choice would be the Something Extra, but you would have to run a tuned pipe, like a Macs Muffler, for the rpm you will need. I've seen them perform well that way. It WILL shorten the lifespan of the engine. Maximum control travel will be required on all of your choices.
