Replying to What twin tips should I get?

Okay in the past I have skied on just about whatever I could get cheap, but still halfway decent. I am coming off Atomic E3s, and I would like to get some twin tips as I am starting to make more appearances in the park. I am also going to be starting my first year on the ski patrol, so I figure I need to look at least halfway proffesional. My price range is $300-$400. I need a ski that comes somewhere in the mid to upper 170s too. Any suggestions?

Oh and please no "You should get because I have them so they must be awesome" Some reasons why your suggestions are good would help. Thanks!
