The only place in PC you really need a full on DH bike is a couple trails at Deer Valley. Canyons bike park isn't steep and is all about flow. My DH bike was complete overkill there, swapped it out this year for a more freeride oriented bike. Not sure how much travel you're working with but odds are it can handle everything up there besides some of the big features on Rally Cat. If you're just learning then stick with what you have to build your skills, then get something more beefy.
DV and I think Canyons too both dump their rental fleet at the end of the season at a pretty nice price point, so that's something to think about/keep an eye on.
