Interesting ski. You could pull some sick ski ballet moves on those puppies. However, I'd pass them up for Alaska. I don't think you'd derive much benefit from the short length since maneuverability through trees and shit isn't an issue. I'm an advocate of fat skis, but for climbing in the Alaska Range you're pretty much slogging on glaciers where the snow isn't too deep, and you want something skinnier to track better. I also wonder about the The "built in skin" and how that would work on steeper terrain and how it effects glide while going down.
I'd reccomend trying to find some used Silveretta 500's and just finding some old cheepo alpine boards that are relatively skinny and light and skins to use.
Ultimately you'd want something light but with some decent girth, like 75 or 80 or so at the waist, but you might end up spending more than $100 for them.
I wouldn't try to do anything "creative," because skis will be your primary / only form of transportation on the glacier, and you'll want something that works well.
