you mentioned the camber combo on the ultra dream...it's allterrain rocker which is flat with rockered tips, so no camber.
I voted for it by the way. I demo'd it last year and liked it. It's a board I would consider buying.
Otherwise, I'd say look at the Burton Sherlock (no B boards in your poll so maybe you don't like them. If so, skip the next bit). I normally ride a 162-164 for the deep pow we have here in Japan, however last year I went with a 160 sherlock with a centered stance...and it floated like mad. I was fine on a 65cm day! The flying v camber is super fun in the pow. This year I stepped up to the 163 and I will be testing it to see how it does in real gnar situations. I'll also be testing the k2 panoramic, which has the same allterrain rocker as the ultra dream, so I'll be able to comment more during the season...unfortunately that doesn't help you much now.
So anyways, I say ultra dream.
