here in the secret that ive had for doing like 2800 or whatever, insanely long spins. when your about to start the game right click and press zoom in. then once the skier gets in the air you take or mouse and " grab" the screen, and move up and down repeatedly and slowly, this slows down the rotation and the height he gets so you can spin more for longer. if this doesnt make any sense. sorry. it works for me.
