Alright, this will be my final update for this since I managed to ride through some pow 8" average fresh at Sunday River with some deeper stashes 16-20" in places. It floated, as predicted, and any time I ended up going over the nose was a result of rider error, either misjudging the terrain or just being too lazy to react fast enough. I don't know if I'd call this a powder boat, especially for those of you who have access to bottomless, unconsolidated snowpack, but considering the size, I think it would do damned well. For shallow powder, it floats great and keeps plane with very little effort.
The base continues to hold up and while not as durable as I hoped (it definitely show its wear) this is a board that could easily go 50-75 days as long as you are just abusing the hell out of it. Rails are fine but rock or even thin coverage will do decent damage.
