Replying to I need some good advice on some good skis

I am crossing the pond after christmas to spend my winter in Whistler BC. I am planning to use my Fischer Atua for park and complement with som semi-fat skis. So the question is: what should I buy if I am planning to do some big mountain but mainly just backcountry?

I am 186 cm and 87kg. As I see it I have got four options.

These are:

Volkl Gotama 190
K2 AK Made´n 189
Armada ANT 191
Scott P4 191

So share me your words of wisdom if you have got some experience of these skis.

PS. If someone has got a hook up for some good accomodation in whistler please contact me.

DS.
