andrew66,

I was at the same point you are a couple years back. At that time, like now, the majority vote was for the Four Star .60. I did consider it but the one trait that really stuck out that I didn't like about the 4* is the tendancy to drop its nose on rudder application. This is the same trait which gives the 4* rather poor knife edge performance. Of the choices you listed I voted for the Sportster because it is probably the cleanest flyer of the ones you listed.

The plane I settled on is the Bruce Tharpe Venture .60. He is the same guy who designed the Sig Mid-Star, Four Star .40 and the Four Star 1.20. The Venture was Bruce's first plane that he put out for his own company after leaving Sig. Consider it a Four Star with all the bad traits removed.
