If you buy the Mojo 15's then you're going to be paying for extra DIN that you don't need. That might not be a bad thing, but since you live in the Midwest and ski park I assume you don't need bindings cranked like Seth Morrison. And to the post above, I've found that Look/Rossi/Dynastar bindings are by far the most consistant, reliable bindings out there now. If you can, find a pair of P12s from a dealer. Rossi/Look doesn't make them anymore, but if you can find them, you'll be happy. The pivot heel is great. They're my favorite binding ever, and although I haven't ridden many others, the feel just seems perfect.
