Replying to Semi-urgent: new skis, Volkl Karma or Dynastar Troublemaker?

Like the title says, I need new skis for this season, and if I get new ones, I'll probably go for the Dynastars for ~$200 no bindings. (I'm looking for a ski that's good everywhere, but especially in the park) I also have the option of getting a pair of lightly used Karmas for $250, also no bindings. The only things that worry me are that the Karmas are supposed to be really heavy, and they're 177cm (I'm 5'9" and low 160s), the Dynastars come in 168 and 175, not sure which is better for me, probably 175.

So, should I go for the Karmas? Thanks, everyone.
