I'm completely new to the ski scene and really want to try it out.  Ive been snowboarding for about 3 years (don't be hating) so i'm not new the park or pow though.  I will be ridin mostly all park about 90%.  I want a good jib ski.  I found a pair of Line Invader's for $200 size 161 but have no clue what size to get.  I am 5' 9'' and 150 lbs.  I also wear a size 11 to 12 boot if that matters.  If you have any advice thank you.

Ok, I will check them out.  Are their any park specific bindings or boots that are more geared towards park riding?

yea the Saloman spk boot is designed for park riding. It's a really flexy boot that is pretty much one of the best bets out there right now. It's also pretty sweet looking which is rare for boots in my opinion. The 4FRNT deadbolt bindings will get the job done in any park.

the salomon spk boot does look prettty nice but ive been tryin 2 get my hands on a pair and i cant findem anywhere but the nordica ignitions look des too

ok thanks but what size should i get?

i'd go with the 176 ski.  its probably the most popular size with the average pros.  almost every company makes their park ski between 174 and 177.  that is the range you would want. 

and for the bindings: if you want a really light set-up(i'd recommend that)  i would go with the salomon z10's or z12's.  they are the lightest bindings on the market and after a season of hard park skiing i know my friend hasn't noticed any damage/loss of performance.

for thte boots: SPK.  thats all i have to say.

oh yea and if you might be interested in moment skis please talk to me.  their website is momentskis.com but it is completely outdated right now.  check it again on the first (of june) for better info.
