Andrew,
The Sig 4-star series has been around for quite a long time now. And there is a reason for that longevity, that because they are great planes. They are very docile and calm down to allow a person move up from their trainer to a 4-star as a second plane, but they can also be turned loose and be a very capable aerobatic plane. IMHO, you can't go wrong with a 4-star. I don't have very much time on a 4-star, but I know plenty of people that will swear by them. Moderator Bubbagates is one of them. I know that his 4-star is his "throw around plane", and he's told me that he takes it to the field with him every training session.

This would be a great choice!!
