Replying to Picking this years ski ?

Had the suspect for 3 years, everytime i got a new pair id break the edge within a week just from sliding rails.   Im sure a bunch of you have had the same problem, and i was just wondering if rossignol or armadas go through the same thing.  Or if there are any other suggestions that won't do what my suspects went through.  Basically i cracked the metal edge, it starts to break off then the base is exposed and then i end up just sliding rails on my base.
