Replying to New Piste & Park Ski's

Hello, my name is Bart and I ski in The Netherlands (indoor snowworld). I am an ADVANCE TYPE 3+ SKIER that skis everything. but, what I'm looking for in this future pair of skis is a ski that is 70 % park and 30% piste.
i ski 2/3 times a week for 30/40 weeks a year. i work at the ski dome, and there are 2 red piste and 1 park with 3 kickers 9 rails and a few little stuff, so there is where i would use the ski the most of the time.

and i go 1 time a year on ski holiday to Austria

I am 23 years old 183CM long , 185 pounds. and my BUDGET IS no more than 500 euro (+-550 dollar) with bindings.

I now have my 4 year old rossignol S2 pro 160 cm and Marker 11 bindings, they are now way to small for me and they are not center mounted.

i prefer the new ski length to be 174 - 185 cm

i would like to have the new ski's to be center mounted, and i have search for a few ski's and would like to know your opinion and advice :)

My searches:

Atomic Punx 182 2015
Völkl Step 179 2015
K2 Domain 174 2015
Volkl Wall Flat 185 14/15

also i would like to know witch binding is the best for me.


Thanks in advance
