you dont need a huge quarter pipe for a good one. A good one is one that throws u up at least a good 20ft. That one prolly wont pop you more than 10ft out because you wont have enough speed by the time you get to the top of it.
but the pipe sloped away from dumont, giving him an extra couple of feet. i know dumont can go bigger but thats cause hes on skis not cause hes more hardcore.
