Sharpening too much? Dont know about that, Im no expert but competetive racers sharpen their edges like every time they race. Yeah fuck rails, I love sliding them, and I will slide more, but only really good ones like when I go to breck (rainbow rail!) I was told repeatedly that rails do nothing to your skis and when they dull you can easily fix it. So at camp I did rails every day for a week and now my edges look like shit. They still ski the same, theres really no change in performance but Im scared of that crack. I dont know if its worth it, if you have a shit pair of skis use those.
