My thought is to pay for a shop to do the mount. I've mounted 100+ bindings, having a jig is the move imo... In Breck we were dirt cheap at $50. Doing it without one could work for ya... Too expensive, high-engineered gear for me to 'just send' on the install. Also measure each ski- I've seen 'rec mount point' lines to be quite off between each. Different bit sizes for different base materials, also some need tapping. You can drill fine but under or overtighten (strip threading) when tightening down screws. What type of glue? Loctite? I can keep going..
Let alone supporting a local business/shop? I've gotten Kingpins mounted at High Adventure twice now. Bought Pomoca skins there also. They seem on point. Makes me feel slightly better about spending their time trying on a host of boots they had in stock, only to search around to save $ online.
OK quality basic tune work and good vibes from management at Potter Bros (Kingston). Good to know about Pro Shop in Hunter.
