a stone grind is more for when you are getting a full tune. Often times they will run your bases with a belt sander to prep them for a hot wax, its not the same though.
I've been wondering will the grinding help alsi skis with extruded bases? I have Line anthems and they are bit slow. Will the grinding make em faster and or help them hold wax better? So will my skis benefit from grinding or is it just waste of money?
