Aerobat Trainer Help
Not on your list but I would recommend the SIG 4 Star 40. Excellent second plane and aerobatic trainer both docile and very aerobatic at the same time.
I have a duraplane stick and while it fly's fine, the aluminum tail boom flexes a lot which makes it very difficult to fly with any precision. If you have the money to keep it, it's not a bad goof around plane though.
