fejas knows his shit, but i just wanted to add a few things.
according to tanner hall, "If you're doing a wall ride or some urban rails in the city, that's jibbing. If you're going skiing, you're going skiing. And if you're going jibbing, you're going jibbing." there are plenty of newschoolers jibbing in the backcountry as well -- off of trees and whatnot. (going backwards is called going "switch".)
"The Pocket Rocket, one of SKI Magazine's picks for Gear of the Year in 2001-02, is one of the original big-mountain super-fat twin-tips. [...] But with sidecuts ranging from 21 down to 15 meters, it's easily the shapeliest of the super-fats. And who says deep-sidecut skis won't skid in powder? The soft and supple Rocket does. [...] It's lightweight, nimble, and noticeably soft, the better to enjoy the sensation of powder surfing. And with twin tips, it's ready to go huge off backcountry kickers." (source)
i see a lot of people skiing inbounds with the pocket rocket and loving it. personally i wasn't even that impressed with it out of bounds, but i like a ski that feels a little more solid in the tips when the ride gets rough.
