I won a Four Star 60 kit and Super Tigre 60 Engine at our Club Christmas party a couple of years back. I too use this plane as a low wing trainer and I have to say that I really like the combination, I find that flying at half throttle provides me plenty of power to do simple maneuvers and I can still power up for impressive flybys. In either case I would suggest the .60 size engine as a good compliment for learning to fly low wings and getting introduced to simple aerobatics.
