I know this is an old thread, but I've been putting this task off and now I finally have to do it because I'm going away next weekend and will be doing a lot of riding. I called my local board shop (I've never gone there before) and asked if they could put some Burton straps on my bindings and they seemed confused. I described the process to the best of my ability and they said "Drilling holes? That's not something we can do." What kind of a board shop is this? Am I underestimating the difficulty of this task? Anyway, I thought I'd try to do it myself. How would I go about it?
