Im looking at getting the 160 clash and am not sure what a good binding to throw on there would be. I am also size 12 boot so should i get large or xl binding? Would the burton triad bindings work well size 10-13+ even though i have different brand boots?
Check the sizing on the bindings. For burton you need a size L/XL (one size). For anything else just make sure it will fit a size 12 or larger. Any binding that isn't made for burton's channel will fit this board. You can use any bindings with any boots, doesn't make any difference.
Large Triad bindings will fit your boots no problem. And they will fit on this board as well as long as they are not EST.
