I just got some FKS 155's and the heelpieces have holes in them where you jab your pole. I really doubt this is a problem, but I dont like seeing holes in my equipment, not do I want to jab it too hard with my pole and break something. Have any of you ever filled them in with epoxy or some other sort of plasticy rubbery compound. Maybe rubber cement? Chewing Gum? Does anyone have any experience with this? I know I've seen many bindings with the same problem.
