Wait, I seem to think you own/owned one of those? Have you tried it? (That would be awesome if you have). The Volkl 2 is one I thought about; Moment is completely off my radar.
FWIW, my Zag H112s will *not* do it - too stiff in the tips.
No, I own the Moment Deathwish. They are 112mm wide, 190cm in length. Great in powder. They are flat underfoot and with a long sidecut so they pivot easy. You can see them in action in my videos
HERE and
HERE from out west. I weight about 180 and they provide enough float out west. I was told the Night Train is even more floaty / surfy and it looked like it would be. Moment makes pretty light skis, no metal, they have carbon and fiberglass layers and they are NOT noodles.
I have also used the Nordica Patron and the Soul7's in powder and the Moments I have beat them in float. The Patron is close though and can be really slashy if you want. I choose the Moments because the can charge in a wider range of conditions. If I were looking for a western powder only ski I would choose the Night Trains 194's no question.
