people will tell you all kinds of different skis, and the truth of the matter is, they are all okay at everything... it all just depends on personal preference and what you want to do with the ski. What I mean is, compared to old style skis, any new ski will do very well in whatever condition you put them in (ie forward mounted dumonts in the pow, or ep pros in the park), the skis are just plain built better and much more versatile.
some might tell you to jump on the missdemeanors, and you would do just fine on those. Others may say the invaders, which would also be okay. But depending on what you want to do, and how you want the ski to respond, you can probably get a better ski FOR YOU.
I personally think that if you want a true park ski, not something like the salomon foil (same exact ski as the lady's mynx), and you want it to be able to handle outside of the park just as well, I would go with the Volkl Wall.
I have ridden this ski a few times and absolutely love how it feels everywhere. It is the perfect flex for an all mountain style Park ski, and it holds an edge amazingly well for a center mounted ski. If you wanted something more along the lines of an all mountain ski, a Saloman Mynx would do fine. If you think you could handle a 167, another great option for a park ski that kills all mountain is a guy's Rossignol Scratch FS, but don't get the girl's version (it will be too soft).
