Replying to Durable Skis?

I am looking for a good, durable park ski thats fits my needs. I ski in the Midwest at a small hill. I love to hit rails and the biggest jump at our hill is 30 ft. I am also around 5' 7 and 135 pounds. I would love a soft ski, that is also very very durable so I know I won't have any problems with edges or a ton of top sheet chipping. The highest price I can go on a ski is $350. I have been riding 2 different pairs of skis this season and both of the bindings got ripped out of the ski. The first was a cheap pair of Elans and the Second was the 2014 Atomic Punx which were pretty good while they lasted. But now I am looking for a ski that I can trust and I know I won't have any problems with in the near future. Thanks
