If you are a beg/int. skier then I don't really see the allure of Louise, you are better off at Sunshine skiing the divide.
I agree. We ski mostly out of bounds at Louise, avoiding the front side of the mountain (under the Gondola) as much as possible. Even on deep days, that area is crud in about 15 minutes. I took my wife to Louise once, and she'll never return. But, she won't go back to KH either!! (The lower mountain sucks big time and there is barely anything off the Gondola for her to ski.)
The only ski hill we both really seem to enjoy is Red Mountain, except she can't ride the Paradise Chair there, as it's, uh, REALLY high off the deck.
Heading west, try Whitewater sometime. I have only been there after it's closed (skinning up) but the terrain is sweet, the snow is deep, (I measured 2.5M at treeline 3 weeks after they closed) and if you're into slack/back country, the lines are superb. The first time I went there, I went with a gal I know from Castlegar. 5'1, 110lbs, and she loads PMGEAR BRO192's into my roof box. Huh? I think I'm out of my league! I was!! She ripped.
As for Sunshine, yeah, it can be awesome, and it can suck bad. We had a great powder morning there last year, only to lose visibility, and then the lifts were shut around lunch as the wind rolled in. Refund? No, we got the finger! KH gave us all back but $10 one day when they shut the Gondola due to wind. But Sunshine has great beginner/intermediate terrain, just stay off the Standish cat-track return loop, as it sucks every day. The backcountry outside of Sunshine is AMAZING, off the Wawa Chair as well as Standish.
