I can definitely agree to the fact Jasper is a lot more laid back than Banff.. a bit less commercialized makes a more chillin vacation, and like you said, can't beat that deal you have going on in Jasper.
It is true that you really need to know the terrain at SSV to maximize it, 90% of the people ride 20% of the terrain. Most of the 'local areas' never get many tracks in them and hold fresh powder every day of the season. I don't live in Banff anymore but I would have shown you around for sure! If you're making the trip let me know and I'll suggest a few areas on that hill to check out, if you can find them with my directions. I rode that hill at least 400+ days and was still findings new areas.
