Coiler AM, Donek FC1 or my Tanker (softies). I find the soft boots harder to ride in the chop than the hard boots, I presume it is a stiffness thing.
As you said, I do not load-up the nose of the board as much since it is easier to go over the nose in the chop. I find that if the snow is that soft, I do not need a powerful carve. If I try to power the board, the snow shifts and I cannot hook-up and rail a turn. If I back my riding off a notch, the board will hook-up, I can rail turns, and the nose of the board does not dive.
