Replying to Kartel 108 sizing

Alright, I am looking into the kartel 108 but I can't decide on the length.

I am 17 years old, 176 cm tall and weigh 73 kg without gear. I ski comfortably all over the mountain ( except moguls, but that really isn't anything I'm planning on using these for). I Iike to go really fast and jump off every roller/kicker I can find. I want them to be be pretty easy to handle in trees and for some air (360, 540, maybe something a bit more complicated) but I still want them to hold up when going fast.

Considering the rocker profile, should I go for 176, 181 or maybe even something bigger? If you think that there is any other ski which might fit me better I'll take all suggestions!
