If the striker and typhoon are no problem for you then I think you are going to be quickly bored with a typical 40-size trainer.

I will suggest something in my hanger a Phoneix Strega 40. it is considerably more capable than high-wing trainers but not something as challenging as a Sundowner. I think this might be something that you could have more fun with while not being overwhelmed. For about $50 more you could get an H9 Pulse which is just as capable and even easier to fly than the Strega.
