I owuld steer away from the super sportster, as it is considered to be a more 'aerobatic' ship, and is certainly more than the sig 4 star. If the super sportster, you might also consider the Somthin' Extra then..

My choice would be the 4 star, as it was / is designed to be teh 2nd plane.

You might also want to look at teh GP 'Slow Poke sporty 40' another easy flyer, that's a tail dragger, and with no bad habits..
