I've got the 2015s, and use them as my only park ski. They are pretty awesome IMO. They are quite soft though, so keep that in mind. I'm not sure of the exact size of the edge, but I have one edge crack in each ski after probably 30 + days of consistent rails. I think that's pretty good. Top sheet chipping is pretty much nonexistent which is nice IMO. Overall I've been really happy with them. I'm 6' 150 lbs btw, ride the 184, and it is true to length. Feel free to pm me if you've got any more questions...
