Sone 720.

1. Ride straight down a well-conditioned medium to slightly steep slope, a notch faster than you would for a Sone 540.

   A backside (blind-side) double rotation needs both height and spin, and your approach speed feeds both. Keep it controllable, though. Too fast and you will under-rotate and land sideways.

2. Bend your back-foot knee deeply and draw your hips directly over the back foot, loading about 80 percent of your weight over and slightly behind the back foot.

   Let the front leg extend slightly and push the tail down through the back foot so the rear half of the board flexes like a drawn bow. That stored flex is what will bounce you onto the nose and pop you up later.

3. From that loaded position, lightly wind your upper body the opposite way, toward your toes, with your arms held wide for now.

   Loading the twist against the spin lets your body carry the rotation off the snow when you release it, and keeping your limbs out wide means tucking them in later will spin you up fast.

4. On the rebound of that stored flex, bounce onto the nose, moving your axis over it and pressing through your toes.

   At the same time unwind your upper body sharply toward the backside to build a twist, and use that twist to pop straight up off the nose. Your spin is set in that single instant of takeoff and cannot be added in the air, so make the switch, the upper-body unwind, and the pop flow as one move. Send your eyes toward the backside just before you leave the snow.

5. Once airborne, pull your arms and knees in tight to make your body small and rigid.

   For the same amount of spin, the more compact you are the faster you rotate, which is how you fit two turns in. Keep your spin axis vertical to the ground, never tilted.

6. Lead with your eyes toward the landing each rotation.

   The backside direction blanks out your vision for a moment on every turn, so keep your head and eyes turning ahead even when you cannot see, which holds your axis straight and lets you spot the ground early.

7. When the landing comes into view, open your arms out to the sides to brake the spin and bend both knees to absorb the impact.

   Spreading your limbs acts as a brake and stops you from over-rotating.

8. Land in your normal stance, weight even over both feet and centered on the board.

   Drive both knees and ankles deep on impact to soak up the landing, keep your eyes down the fall line, and bring your chest up.
