Dave, the US 60 would actually make a great 2nd plane. It will slow down so much for landings that it is almost laughable, and with low rates set (or the control throws dialed down a bit) it can fly very trainer-like. When you feel like going inverted or doing some aerobatics it's still comfortable with the symmetrical airfoil and zero dihedral built into the wing. As you get really good with it you will discover that it does not like to knive edge due to the fact that they have a bad rudder/pitch coupling issue, but it was never designed to be perfect for aerobatics or 3D. It's so good at sport flying though that this is usually overlooked. I think it is the high wing and low stab that does that.
