Quick question. In 2009-2010 year I was at Killington late in the year and it was pretty bare. Needless to say my edges got pretty banged up and they feel all jagged (not to mention rusty). Whats the advice for the first tuning of the year. Should I take to a store and get it done on a machine then use a file to set my angle or should I use the file and forget the store sharpening of the edge and base. I usually use the progressive diamond stones but I think I am at the point where I have to do something drastic. Any advice would be greatly appreciated.
