Replying to Bunch of skis, pick one for me.

Yes another one of these threads.. I have narrowed my future purchase down to a couple of skis based on my style of skiing. I like to do 50% all mountain/powder skiing and 50% park skiing, i like myself a flexible ski for butters and landing back/front seat. Rails, man made jumps, and cliffs i like them all. At the same time i want the skis to be able to rip in the powder if there is any.

Which ski would you pick out of the following

2011 k2 kung fujas
2012 line blend
2011 4frnt VCT turbo
2011 rossignol S5

or suggest me a ski around those price ranges and specs

thanks +k.
