Tonight after skiing I noticed one edge on my concepts is cracked. Right in the middle, all the way through. Its pushed in a little and the base is bulged out a tiny bit at the spot. No Idea how or when it happened. They seem to be holding together alright now but looks like I'm definitely getting new skis now. Its last years ski so no warranty left. Doesn't really change my opinon on the skis at all. I'll probably get troublemakers next in fact.
