Even that those planes have the wing in a high position, they aren't trainers, and in my personal point of view they qualify for a third plane. Do not rush, you have tasted the lack of confidence jumping from a trainer to a Phoenix Dolphin, I would suggest (against your position) to go for an avistar (which is way more aerobatic that a common trainer). Build confidence and then go for a low wing trainer.
That is just my opinion.
