AqueousBeefwrote a review of Burton Mission Snowboard Binding on April 2, 2009
These bindings would be great if I had used them for their intended purpose, park-riding. Although they are advertised for all mountain riding they are much to flexy to go at the speeds I want to over the terrain I want to. I like to go fast and don't really hit up the park, when the going gets rough, the flex begins. These are by no means recommendable for the whole mountain. Don't be fooled by the "All mountain" monicker, they are very comfortable but are much too flexy for my taste. If you find yourself more often on the double blacks than in the park, these are not for you.
As a side note, the ankle strap padding ripped a fair amount after 2 days of hard riding. The straps themselves have held up well though.
