Replying to Fischer's Addicts - the right ski for me?

Hi All!

I'm 178cm and 66kg (I hope the european dimension is ok for you)
I've started to ski one year ago with salomon 720 (161cm). I spend the most time (50%-60%) with my girlfiend and friend just cruising.
With the new ski I don't want to do BIG JUMPS and BC because of my damaged knee (6 years aggressive inline skating). I want to grind lower rails and boxes also do butter trick and ollies. Very important for me is riding switched (I love it) But don't forget the 50% percent cruising.

The skis I would choose from are:
1) Fischer Addict: perfect for riding switched and stiff - good for crusing? Maybe to stiff for my low weight and for doing butter and ollies?

2) Fujatives: perfect for park but what about just cruising and ice?

3) Salomon Foil: ???

What about the lenght of the skis - is 170cm ok?

I hope to get helpful answers :)
