You're better off looking at some reviews in the review section. People ripping out edges most likely did a lot of jibbing and hit some rails so that edges came out, just like what can happen on every ski. Also core shots, they probably hit a rock, got a core shot like any other ski.
My MSPs so far are bombproff, pretty stiff ski but they are softening up and I like them more as I go. Next year STLs seem really improved...
