I was recently embarrassed in the ski shop when I was buying a sharpening file for minor touch ups when I asked the ski shop owner what the difference was between an edge angle of 88 and 89 degrees. His answer was that I didn't have enough experience to tell the difference anyway so not to worry about it.
So, clearly, i don't have that experience because otherwise I wouldn't be asking that question, but that was a little harsh i thought. Anyway, can anyone please tell me what the difference is? Also, how do I tell what angle they are currently at (besides breaking out my protractor...)? Are different angles better for different types of skies or skiing? For reference the ski in question is a Sultan Legend 94 at 178cm.
All I want to do is clean up the edges very slightly where I hit some rocks but I don't want to mess up the angle of the edge.
