To be fair I watched the supervisor of the place have to explain to the tech what to do like 4 times because first he wanted to just measure up 4cm from my -4cm previous mounting point (which would have worked but still) and then he thought center mounted ment the top binding is mounted on the center line. Thats what I get for going to Sport Chalet instead of a ski shop but Sport Chalet is like 2 minutes from my house and the nearest ski shop is a 30min+ drive, and in the opposite direction of the resort lol.
Now at least I have a Dick's Sporting Goods, they carry a lot more park skiing gear than Sport Chalet. And by a lot more I mean a few pairs of twin tips and one pair of park oriented boots.
