also consider the banana magic. I ride cypress/whistler/baker. For these conditions the magic 157 excels. Premium edgehold in ice. But never catch edges and faceplant. Also my supermodel x 164 is awesome for pnw. Carves better than magic. Faster. To me the smx is my big mtn board when i go to whistler. If theres mixed conditions and/or i plan on hanging out in the trees (limited viz) the magic is what i reach for... more manouverable, shorter.
For pow these 2 are about equal. For epic pow i use my fish ltd.
