Replying to Beginner freestyler, help me choose please! :D

I am an expert skier, 155 pounds, 5'9. I ski at Whistler and occasionally the Banff area. I am looking to buy a pair of skis that i will be able to keep up with my usual riding while also being adequate in the park and pipe, as i am interested in learning how to freestyle. I want a ski that is nimble but also stable for skiing in trees, steeps and deeper powder but also able to charge through some of the rough patches and hold a decent edge on groomed runs.

I think i've narrowed it down a bit to these skis:
Line Anthem
4frnt MSP
Line Blend
Line Elizabeth

Please share your opinions/knowledge about these skis and which one would be a good fit for me and why. It would be greatly appreciated.
