RE: Looking for something I can get aerobatic with.
After re-reading your post.
Yes the low wing sonic will do quite alot of aerobatics and make a great second plane.
Learn basic aerobatics first, forget the hovering until you can do strait line aileron rolls, inverted flight all the way around the field. clean cuban 8, and a whole long list of other maneuvres that don't involve 3D. at some point you will be able to do a rolling circle when you do, grasshopper, you will be ready for 3D.
