Just as he said; all the 2010 skis are pretty innovative. Instead of being skis that perform only good overall, pretty much every brand is releasing skis for different purposes. Personally, I ride for Dynastar&Lange, so I vote for their skis, and the reason for why I do that is because I've only been on the team since I turned 16 back in May, but in such a short period of time, their skis have impressed me far beyond what I thought was possible. I didn't really like the new design on the troublemakers, and the fact that the tips split up after a good three months of hard skiing, but besides all that the troublemaker have been, and always will be one of the best park skis out there. Now, they've released a new ski, double steel edges, wider, better design (god damn they needed that) and pretty much turned an old design into one of the best skis of all time; with the new 6th Sense Series. But since you want me to rate three skis, I'll rate you three skis and tell you something about them too, so you'll get a better piture of each ski and what you may use them for.
Dynastar 6th Sense SPIN - The reason for why I name this ski is the same reason for why I applied for a sponsorship deal with Dynastar in the first place: In my opinion it's the best ski out there, for mye purposes, which is bigger jumps, a huge variety of rails, in short term - A killer ski in the bigger parks.
LINE Chronics - This ski is worth every single nickle you put into it. The ski is slightly stiffer than the rest of the Line Setup, making it good for bigger jumps. As far as construction goes, I think I'll place it right behind the Völkl Walls and the Ar6. Although it's more of a jump-ski, I feel that it's got slightly better spesifics for railing, than jumping; although, as said a perfect ski for bigger jumps.
The third one I am going to mention due to the fact that it's proven to be extremely durable; the LINE Afterbangers. This is a lighter ski with the "skateboard"-technology everyone first was scepticle to, but soon learned that the ski's motto: Ski and Destroy had been given this motto, due to this "rail-proof" construction. I prolly should have mentioned the Ar6 from armada here, and the völkl Walls, but I find them pretty simmilar to the LINE Chronics, but in my opinion those two skis, are right behind, or beside the Dynastar 6th sense SPIN, so I won't bother tell you about those. Now, back to the afterbangers. The afterbangers is a ski, proved to cope with almost anything, but I've tested it, on everything from Small to big jumps, to sharp kink rails and whatever you can mention. Suberb control in smaller parks, but might loose to another big park ski when it comes to the bigger jumps, because it's slightly lighter than the skis mentioned above.
Good luck choosing, take your time; you're going to need it with this year's lineup.
