Hey guys. so i just came back from sporting life dropped off my skis so i can get them tuned for my provincial races coming on monday and tuesday of this week. I got a Hand Tune, which is what they reccomended to me, and at $65 each, i'm hoping for a good job. So apparently it includes race wax, and edge setting and sharpening. i've been always getting the skis at store settings, and i've always had problems with grip. They reccomended i get a 1 degree - 2 degree on my Slalom skis, and a 0.5 degree - 3 degree on my Giant Slalom skis. What does it actually mean? and is this an edge setting thats gonna help me with grip on ice?
how durable are the edge settings? how long are they gonna last? they have to last a whole day of skiing for each ski and 4 races through out a day.
any help would be good.
