Thanks for all the information, folks. Since this is going tobe my first big plane (and first low-wing) I'm looking for more sport performance. Something that can do some aerobatics, but isn't a handful to fly otherwise. From what I've read here, it's looking like I'm going to stick with my initial decision and go with the Sportster. Maybe I'll go with the Chipmunk a little farther down the line and put a 26 in it.
