Replying to Stiffer Skis

Hey everyone. So I've been skiing on some '07/'08 Line Anthems. They're sick skis, but I'm done with the butter-zones, etc. I don't butter much. I also land back-seat, a lot. I'm sure the majority of it is just because of me, but maybe the skis have something to do with that and the way I land.

I do about 70% park, 30% groomers. 50% Jumps, 50% Rails.

So, any suggestions on some stiffer skis? I was thinking either the Chronic or Chronic Cryptonite. I like the idea of having a wider ski (going along with the Anthems), but I don't know the necessity of it. Just from looking around, it seems like most companies offer more flexible skis. I'm having a hard time finding a stiff ski.

Any ideas? Thanks!!
