As has been said so clearly until now...you ravaged those skis.
Are they park skis? Yes.
Are they designed to be ridden in the park, and therefore on rails? Yes.
Will ANY ski you use on rails eventually blow out it's edges and get the damage you have on yours? Big fat yes.
Simple fact is that they warranty against "manufactured defects", like for instance your edge wasn't set properly, or something else that it came from the factory with.
Your skis from the factory were in awesome shape, you did all the damage, blatantly and on purpose by riding the way you did.
Move on, use these as long as you can, then make them your urban ski.
