Replying to Not another LOL HELP ME FIND A SKI thread.

Alright, so I got me these K2 PE's that I absolutely love all mountain, but they're just too stiff for park and I'm having a lot of trouble progressing there because I can't pop for shit. They have about one season left on them because they got some cracked edges and other bullshit. My plan is to use them for all mountain and finally get my hands on a dedicated park ski.

What I'm looking for...
1. All flexey and buttery and poppey and yay.
2. A ski that is going to last more than one season. As I said, my other skis are on their last legs and I don't want to be slapped with buying two new skis next year.
3. It does not have to be good all-mountain. At all.
4. $200-$350. I am very poor.

About me...
1. 6'0"
2. 150 lbs, but pretty strong, I work out
3. Been skiing for a long time, pretty comfortable/advanced as far as just skiing goes, but in the park I'm in the early stages of progression (270s out, 360s off jumps, etc)

I was thinking Invaders or Chronics as I saw them in the B/S/T forums, but I hear the Invaders are great for a season then they blow up, which made me a bit wary. Suggestions? Thanks!
