Replying to Karma vs. Tweak

Ok, I'm going to get some new skis this year, and I want something that will be good in the park, but I'll probably mostly be spending time on the rest of the mountain. I love the Volkl Karmas, but they're expensive. I like last years Atomic Tweaks too, and they have a much more managable price. Both seem to be a pretty good fit for what I want to do. I know most of you will say the Karma is better, but is it $200 better? And has anyone by chance skied both and compared the two? Any input is appreciated. Thanks
