^^in PC, ive found that the consensus is that canyons is the best mountain for pow in PC. I wouldn't know too much about it, since I'm almost always at PCMR, but with new snow, its hard to go wrong.
Deer Valley is pretty fun as well, with free Rossi demos at the base of empire lift (with s7's and bc110's), all you need is a credit card for deposit. They did this last year, but im not completely sure they're doing it this year... I dont see why not though. If you go there, I would suggest staying at Empire/Lady Morgan (Daly Chutes are super fun), or maybe Mayflower, where the steeper runs are, with smaller crowds.
If you go to PCMR, theres always a big rush to Jupiter, so if you get up there early enough, that's where most of the best terrain is (steeper, a few cliffs, big bowls). If you are just looking for tree skiing, then the trees off McKonkeys, Thaynes and Motherlode are usually pretty sick.
