Replying to Buying new skis now... need some input

last weekend i broke both my skis and bindings (salomon crap) during a competition :(
so now i need some new skis and bindings fast.. I am currently deciding between:

mainly
176 mik d pro or 183 stl

but I can also pick up some
07 Invaders and 07 Trouble Makers

..I really want the mik d's, but they only come in 176,
and im 181 cms 68 kgs
(5'11 150 lbs i think) so..are they too short?

I only care about the performance in the park.. what would you suggest?
Thanks for fast answers
