A few things to consider:
K2 measures their skis really short. A 179 K2 is more like a 183 from another brand.....that said, they are all rockered this year, so they will ski shorter.
The Silencer isn't really a stiff ski as far as park skis go. It is much softer that comparable counterparts such as the 2012 or the halo.
It is an awesome ski however, playful, buttery, and really really fun.
PBR is so much more than a breakfast drink.
Shake that bear.
