i really don't know a whole lot about edge's and bases, but i'm wondering how big of an issue this is. i just noticed that a small piece of edge is missing underfoot on my right ski (my lead foot on rails). the edge is almost completely rounded over from grinding considering it's what i mainly do here in shitty wisconsin. is this a big deal? what should i do about it? i guess the only thing i've thought to do is switch my skis from left to right so the other ski can start to get beat down.
