So, I took my beautiful BROs to get mounted.
Read some threads here and there about how 3mm in front of the line is the way to go and all that.
Agonized what shop to go to after reading some threads about people getting their BROs mounted wrong.
Talked at length to the shop owner about it, got remarks how 3mm don't matter. Ultimately they decided I was nuts, but harmless, took detailed notes and said the tech will call me first.
The tech did call. "3mm in front of the line? No problem. But in front of the line on which of the skis? The lines are in different locations."
