Upgrade your gear..
I got my 2006/07 Burton Mission Binding, but I saw the new 2008 model have a modifed Capstrap, so I get the super capstrap to upgrade my bindings.
This new capstrap give me more force when I make a turn in big air.
I have a Burton and Salmon Boots, it can fit both boot's sharp easily.
The only concern is the price, it is not cheap.
