I've got a pair of 09 Chronics.. I don't know what they compare to the masterminds or afterbangs.. But they're a dope ski bro! I don't ski much park, just a little bit, but they're pretty sturdy ski's in the park, and I've heard good things about them elsewhere about how they handle in the park. But they carve really well, handle groomers in generally really well. With the 85 waist.. They're not great in a proper powder, but if it's shallow then they're fine. If you want something wider, look at the cryptonite!
