Just Got the CUSTOM X Wide board and was introduced to the EST binding system. I figured if I put the money into the board I might as well make sure that I get ALL the benefits of the system. I have never been more surprised at the simplicity of any equipment. Two screws put them on, there is a window that shows a "reading" of what degree your bindings are set at, and a window that allows you to see the board below to locate the reference marks to adjust if you are stance forward or want to be exactly in the middle of the board. I had them on and adjusted in 5 min. The other cool thing about the way these bindings are set up is if you need to adjust the angle of the binding on the board you can do it with your boots still on. Also, the they feel so secure because the screw spacing is so wide. Your board feels more responsive, not to mention that you are able to feel the board better because the bindings don't have a traditional "plate and base" system. I highly recommend looking at a pair and seeing how amazing they are. If you are going to by an EST style Burton board, spend the extra money and get the EST bindings. You will be very, very happy with your decision.
