All nice airplanes. I`m a confirmed fan of the Avistar. If you`re a relatively new pilot, it might be a nice choice. Avistar can be a bit more frisky than a flat bottomed wing trainer, but hardly unmanageable. Now, if you should elect to upgrade a bit and put a 46 up front, that can be a different ball game! MUCH better airplane, IMHO, with a 46. Properly set up will do all the basic aerobatics.
