[INTERACTIVE_SLIDESHOW]Make sure you have twin-tips and get used to skiing backwards. Find the in-run of a jump. Ski backwards towards the jump. Approach the lip looking over the same shoulder that you naturally spin towards. As you hit the lip, it's going to be a subtle movement. You have to watch the lip. Spin when you hit it. Look over the same shoulder as you spin and make a subtle movement.
By looking over your shoulder when you go big, you'll spin automatically. It's important to be really centered with your weight above your feet. If you're jumping small, you'll have to set some spin, but the bigger you go, the more natural it will be to just turn around. When you're used to going fakie off a jump, you completely forget the first 180.
