I live in Cranston (south calgary) and castle is a few km closer to my house than LL so im sure its pretty close to you.
I really like ssv but they need to move the park to a run surrounded by trees on goats eye. SSV has better snow and a longer season with cell reception on the whole hill. LL has a way better park but i don't think that matters to you.
The only down side to ssv for you is that so much is above the tree line so if the light sucks you are stuck in a few areas, where LL has much more terrain bellow treeline.
