I have been flying a Sport Cruiser through most of my training and since getting my ticket. I LOVE the SC. I started originally with a 152 and the difference is significant. The SC is much roomier, more responsive and I think more fun to fly. Besides that, it just looks cooler!
Definitely get several hours of instructor time. There are differences (low wing vs. high wing just to start) but once you get comfortable I think you will love the Sport Cruiser too. The visibility is awesome!
I have a "training version" of the Sport Cruiser POH in pdf format. If you would like a copy, just drop me an email. email@example.com
