Should've mounted my own fucking skis...
I just got a pair of new one eighty fr dimes. I don't have a four point one bit or tap and was feeling lazy so took them to a shop. Marshal put on the ski, mount negative six from true center, negative eighty four from tail. Shop guy measured eighty four added six and basically mounted center. On the phone he didn't seem to comprehend the mess up and insisted he mounted according to the instructions. I wasn't likely to ski them this season anyways, but looks like Im ordering the bit and remounting myself this summer.
