Replying to Best skis to get but not to expensive

I am a skier that likes to do a lot of crazy stuff. Hit rails and try new things. Since I hit rails constantly I want a really durable ski that has pop in it for those high rails. I don't want to butter the ski and have it snap. I also like play for butter on the snow and bit to stiff. A pretty light ski so I can flip on jumps. My previous skis the edge shaped in one session so I want a ski that has a durable edge. I want a light enought skis for big jumps and flip them. I am 115 pounds and 5 foot 5.
