I suggest looking at some mountaineering backpacks in addition to (if not in place of) the Burton's and Dakine's.
Most of the winter alpine packs that have ski carry also now include board carry.
Osprey and Black Diamond would be at the top of my list.
IMO you may pay a little more but you will get a serious product with better craftsmanship, materials and features.
Resort packs are for leaving at the top of the park.
