Well it's time for me to take my skis in to get mounted. I've read some horror stories about shops messing up the mount. Over and over again people have said to draw a line were you want them mounted and make it clear to the tech that that is were it needs to be mounted. This I plan on doing but I'm unsure of how to correctly messure. The skis that I'll be mounting are a pair of 07 Line Elizabeths and I want to mount them -2cm from TRUE center. What is the correct way to go about measure so the shop tech has no excuse to screw it up?
