You need to be slapped in the face real hard for wasting 2 weeks on this stupid worry of yours. Mounting bindings is a simple and dumbproof process. If you have a mounting jig, which the ski shops do, then anyone who can operate a drill and turn a screwdriver can do this in about 5-10 minutes. Worst case the shop will be liable for any screw ups.
hey Arnold, threats of violence are not cool. have a seven day temporary ban to chill out. if this doesn't fix your problem, longer bans (up to permanent) are available.
