Replying to 1080 PR PE Which one???

Hi everybody!! This is my first post. Ive got a doubt It should be great if you can give me advice about this matter. Im gonna bye a pair of twin tip skis but I don´t know which is better for my style of skiing. I want them mainly for powder but they must be twin tip because I wanna practice in the park. I´ve said that I want them for powder but where I live this kind of snow is not too much usual so they should be the most versatile as they can be. Anything more?? Haha Well so I spent some time in piste I´d like that this skis had a good sidecut so the radius must be as small as possible and with the toughness not too soft.
What I really want is a twin tip for all mountain.
The shop where I´m gonna buy them sells the 1080, Pocket Rocket and Public Enemy. I don´t know if the 90 mm Pocket Rocket waist is too big for going on piste and my style of skiing. Besides everybody say that foam core of salomon skis sucks. Has PE wood core?? Perhaps PE is not stiff enough to go strong. Wich is the toughest one?
Finally people talks very good things about Mad Trix Mojo but I can´t buy these in this shop.
What do you think?? Which is better for me??
Thx
