Replying to Whistler skiis

I need some advice on what to get- I'm heading out to whis for the winter, and Im going to retire my 03 xscreams. So far I'm tied up between elizabeths, prophets (100s) and scratch BC. Im 5 10, about 15-ish pounds, and east-coast raised. So I need something that rips in powder but that I can manage, since I've never skiied anything more powdery than tremblant

and if the lines are the best bet, have they finally got their shit together? Everybody I know who bought them the last few years had them delam and then take about 6 months for the warranty to come through..

oh yeah, the breakdown: 10% groomers, 10% park, 70%GLADES GLADES GLADES and about 1-% moguls, when I get bored. BUt I want to get into backcountry as heavily as possible.
