I used to ride at Crystal and Snoqualmie often. Everything about those mountains says to me go with the NS Cobra. Built with pow in mind, but not powder specific. Directional, so better than the Heritage/TRS if you don't ride switch often. Good compromise of stiffness and flexibility. Not a park board but not a super stiff freeride board either. If you are riding at Baker though, you might want something a bit more powder specific...
Based on what I've demo'd, I like the camber/rocker/camber setups on NS and Lib better than the rocker/camber/rocker setups on other board lines. The former has more grip near the tip and tail (which I like better for carving), the latter has more grip in the center, which kinda rides more like a skateboard a little bit.
