The board performs great in powder. It is even better on groomers/packed snow, allowing me to get a good grip while speeding down the mountain and through turns. Very happy with it. It is very responsive. I highly recommend it, especially for big footers.
These bindings are great as far as comfort and feel. Yet I do worry about the structural composition, by the third day I bent the heel cup and hadn't ridden them hard. I was very surprised since a have an older pair of Super Sports that are bomb proof.
