Do you want a powder ski in the PNW?

As a second ski for the quiver? There are some cheaper demo skis like the Atomic Backland 107s and 117s that have me tempted.

I'm 5'10", 155 lb on my second season with a new mindbender 96C for this winter. I'm mostly at Snoqualmie but plan on a couple of trips to Baker, which has prompted the shopping.

For a second ski, how wide is enough of a difference? Is 106+ enough for Baker? And should I be looking at heavier skies to make it through the PNW crud?
