Replying to I need a bombproof ski...

so im coming to terms with the fact that my STLs probably wont make it through this season.  6 edge cracks and counting, and the pressure from me dipping my edge on boxes is starting to crack the layer under the base.  and this is all form almost a years use.  so im looking to invest in a new pair of skis soon, and i want something beastly.  id really prefer a symmetrical ski, i was looking at the walls, or maybe moment reno jibs/rockers.  so what im asking is, what are some good, durable park skis that i havent thought of yet?
