I remember one year at SES, ATC ( 2016?)the Montucky boys kept me pretty busy in the garage. I will always remember looking at Johnsamos edges on the racing stripe board and they were perfect. Perfectly rounded. No nicks gouges, just rounded. Pull your finger nail across, no shavings.He thought he had about 2,000,000 ? vert on that board. Never tuned.There was some hard snow that year, so yea hard snow makes a difference. On the opposite side I know a guy that brings 2 boards to the hill. A morning board and an afternoon board. After you ride the boilerplate in the morning, the edges are shot and so you grab your afternoon board with new edges. I used to be pretty anal about edges. Now I’ll set the angles, usually 1/2 or 1/3 and just do some light diamond passes to remove burrs daily( rocks and bushes more common this year). Technique is by far the most important and goes a long way for sure, but when the snow is really hard ,edge sharpness does become more important. Put a good rider on hero snow with dull edges, I’ll bet he/she is going to have an awesome day. Put the same riders on really hard snow / Icey with dull edges, I bet they won’t be so happy. So I don’t hit my edges with the file that often when it’s softer snow. When it’s harder, then I think it’s time to use some of that Rockwell you paid for.
E Bellissimo. Of course when you’re making 6” trenches, you don’t need no stinkin edges.
