Shit, I don't care if it's too months late, because hopefully people are using the search function to answer their questions anyway, since there is a wealth of info out there, so I'll add to it.
I did a Kicking Horse / Revelstoke trip. One of the best experiences I have ever had on a mountain. I did see you mentioning enjoying trails - which I would say can be limited here, as it's all about making your own trail. But for sheer powder, varied terrain, and endless possibilities, these two resorts were amazing. It would dump, and you would still find stashes 3 days later, and you didn't have to know the mountain that well to find it.
