Flynnc21i own a pair and they are a park ski but are not a top of the line park ski. you could definitely use them as an all mtn ski. they are prone to edge cracks but i think that will only matter if you are going super hard on rails.
You wont get an edge crack from carving hard unless you hit a rock or maybe a really big piece of ice (doubt it). Park skiing crushes skis. Accept it before you do it
