Replying to New Line Chronics?

I currently have the 05 Line 1260's and my edge's are cracking. i cracked one a little bit today of park riding but i dont mind that much. i was wondering if the new line ski's are stronger or the same. Its prolly cracking from the corners of boxes and rails like that. i dont have problems with butter boxes, shotgun rails, normal boxes, c boxes. its the ones with sharp edges that cut up my base. So i was wondering if they are stronger then they were. and if there is anything i can do to add some support to the broken edge.
