i would reccomend the Armada AR5's, although they went through quite a redeisgn, if they are half as good as last years, they will be amazing. i found that ski to be a great all around, it held it's own in the park, jumps and rails (not to shabby in the pipe either), as well as through the crud and choppy snow. It wasn't too bad in the deep stuff, a little more float would have been nice, but nothing to complain about. on the groomer's it carved pretty well, wide turning radius, fairly responsive, but definetly not a race ski.
if you want a ski which is more big mountain specific, but still has all mountain versitility, go with the seth vicious'. the seth pistols were great last year, and i believe they have stiffend the flex for this season, which is very good. the pistols had great control in the deeper snow, although i found them a little soft for my likeing, although they stiffend the shovle i think, so i'm looking forward to trying them this year. out of the deep stuff, they were a really fun ski to take everywhere, even in the park of jumps, since they were so much wider then the AR5's they slowed all my movements down in the air... i dunno, they were heavier.
finally if you are looking for a park specific ski, the T. Halls would be my recemondation. they are really the only 'park only' ski out there. with a flex pattern specific for buttering, soft in the nose and tail, but stiff under foot, with rounded edges in the centre for easier rails. they are super light, and with a salomon binding on there, you'll feel like you have snow blades on your boots. but if this is the only ski you take to the hill, you will be stuck in the park for the entire day, it blows in the 'all mountain' department. The fujative might be another bet, park specific, but with a bit more all mountain.
