I say 4 star or a supersportster (its what I had but make sure you can really fly your trainer). Your second plane will be so much more fun than your trainer. It opens a whole new world in aerobatics. By the way, Ken your list is huge. When you post your list I think it would be more helpful if you could also include which are some of your personal favorites. If one were to thoroughly research all the planes on the list it would take forever.
Good Luck
