Replying to Cat skiing in BC

I would like to cat skiing with my sister this winter. We would like to hear your opinions on the best places in BC. We are both expert skier and the most important thing to us is terrain and snow. Of course it wouldn't hurt to know about what the lodge and commute is like at those places with the best terrain. Now what I mean by best terrain, to me, it is the terrain that is the most challenging and fun. We are looking to go for 4 days, and price isn't a huge issue to us. Thanks so much, and we are looking forward to hearing your opinions.
