I havn't read all the articles, to be honest, I've never visited that section before.
Maybe update the factory edge angles from posts on this page. And to name a few -
Tuning kit Tool lists
Variable Base Bevels.
Extruded vs Sintered base discussion
Waxing for regions - east vs west
Edge angles for different types of skiers and skis, and regions
Stone grind structures
Heli - coil or insert installs
Handheld machine tuning
Recommended service shops by region
Thats off the top of my head. Maybe some of this has been discussed in the forum articles already. I'm sure others can chime in with better suggestions.
I just want to help make this awesome place, even better.
