You'll probably be fine on them if they're your first park binding. They're not that great, they're a step below the px12 (they have more plastic and a more release prone heel piece), but since it's your first year it's not too big a deal. HOWEVER, don't expect them to last you to next year, you'll want an upgrade by then, just putting that out there, so if you really want to, spend the extra cash and get a better binding that will last you longer (or just wait till next season when you know how you've progressed in the park and you can make a better decision).
