Add the Tiger 60 to that list. It was my second plane and I still have and fly it. My original config was with an OS 61 SF which pulled it around just fine. The plane is larger than a 40 size but handles like a smaller plane, like a low-wing trainer yet capable of doing aerobatics. It has a two part wing (the ARF) with an aluminum center spar that makes easy transport. I 'upgraded' mine with a Super Tigre 75 and later on, after having some interesting muffler problems, a MACS Tuned Pipe, which is also a great combination. One guy at our club has a 90 four stroke on his and it too flys just great.

Also, the Four Star 60 is in the same class and is equally easy to fly and very capable, but I believe this plane is one part wing (does not come apart.. someone may correct that if it is wrong).

I like the larger size, clearly improves visibility. After flying it for a short time, I was able to see everything that was going on during landings and actually see how the controls (elevator/ailerons/rudder) work during the slow flight during approaches and landings. It really helped me improve my landing skills, and of course, my flying skills.

Two great choices you may also consider.
