I have been to Schweitzer and it is a big area. After being at Red and Whitewater, as well as Fernie and Kicking Horse, Schweitzer was a whole different experience, with high speed six packs and big weekend crowds. While it is more of an intermediate's paradise, there are some tight trees and steep faces to keep the advanced skiing entertained. The views are spectacular.
Red is my favorite mountain ever for tree skiing. The trees are steep and while i was there the snow was beautifully dry, even though it was a week old. My resort feature can be found here

Whitewater is not big, but gets continuous snow and is a powder paradise with some very nice side country tree skiing.
You can hit Red, Whitewater and Schweitzer from Spokane easily in a week's trip. That's what we did. There are about a dozen cat ski operations in the Nelson, BC area, so if you have $275, try to get on a cat standby...it's cheaper than reserving in advance. Great if you are just one or 2 people.
I think for a Feb vacation, it should be a good bet for powder...especially in a La Nina year. It is one of my favorite places to ski. I need to get a new passport so that I can go back.
Oh, and as far as Fernie and KHMR...Kicking Horse kicks butt if you hit it with good snow. The terrain is super, really awesome steep bowls, some steep glades and really long runs. If you can do 6 runs, you've had a good day there. We hit it good and we were so tired after 4 days of Sunshine Village and Lake Louise we could hardly do it justice. We noted it as a place we must get back to. It is pretty cheap to stay in Golden as well. Getting there can be a challenge and expensive though. It is a pretty long drive from Calgary and Spokane.
If you go to Spokane...visiting Red, Whitewater and Schweitzer (and maybe Silver too) would be a fantastic week. Save Fernie and KHMR for another trip would be the way to go, unless you got all winter to bum around BC.
