I'm going to disagree with the contact pro assessment.
They're carbon injected and have a responsive, but flat highback. They're on the softer side, but they are by no means only for park and Jib. They're currently Gigi Ruf's pro model and I wouldn't call him a park rat. They have more lateral flex than the Atlas/Force, but, for me, there was no drastic loss in response straight back.
As far as Unions go, Pros and the Atlas are can't go wrong purchases for all types of riding.
Gigi rides the superpro's. The contact pro's have a lot of torsional and lateral flex. So much that I don't even like them for park. Too loose feeling.
