I too looked closely at this pack and the DaKine Sequence. Both were well built with the DaKine taking an edge there. They both held about as much photo gear as I want to carry skiing. The main reason I got the Burton was that it just felt better on, it seems to hug my 210 lb frame better. I would suggest you try both out for yourself if you can as the DaKine is no slouch of a pack at all.
I typically carry my 20D, 10-22, 24-105(or 70-200), 50 (or 85), 1.4 TC, 580EX(sometimes) and lots of goodies.
The rear outside pocket will carry a shovel and poles, or you can stuff a jacket in there.
The side mesh pocket is no good for a water bottle, it would fall out easy. The zippered pocket on the other side is quite handy.
One other beef is I find the sternum strap way too high up and it can't be moved lower.
I have rolled over hard on this pack a few times as I do not take it easy at all with it on and have had no damage at all to the camera gear. I would not use a Rebel (or Nikon's equivalent) plastic body in it though.
This is a quality, well built pack that works great for its intended purpose.
