Hey NS
I am currently training for my level 1 PSIA (professional instructors of America) exam and I noticed that my skis really didn't have good grip on the harder snow and ice. I have 2 pairs of park skis that have both seen rails. I know park skis aren't necessarily ment for carving and rails ruin edges over time, but would an edge tune make a significant and noticble difference in my grip on harder snow and ice?
K+ for any help
