So I've noticed that one one pair of my skis, I can see the outline of the edges through the bases. I bought these used from ebay a few years back, the skis are Volkl Racetiger GS, race stock 23m version. Here's a picture of what I'm seeing, though it's harder to see in the pic. Also, I can see them much more clearly if I've just hot waxed and there is a layer of wax still on the ski.
So should i be worried about this? I'm guessing it won't be a problem, but I'm wondering if it is ok to take them for a stone grind, or if they would be down to nothing afterwards?
