As you take off, bring your legs back up to your body and keep looking down at the snow under your leading arm (or back over your shoulder if you’ve taken off from your toes) – much the same as the frontside 360. Reach down and grab indy – it’ll help you achieve the best body shape for this trick.
By the top of your air, you should have swung around to face the kicker, and you should basically be heading bum-first towards the landing. As the landing comes back into view, focus on where you’re about to touch down. Unlike the backside 540, you get to see the landing from here on in, so things are a little easier.
If all has gone well, you’re heading back to the ground in a fairly upright position and can judge the angle at which your board is coming around. If you need more spin, pull your knees up. If you’re rotating too fast, open up your body. Extend your legs, lowering your front leg a little further than the other so that the board lands nose first on the landing (remember you’re landing switch, so your nose has now become your tail). This way, if you’re a little out on getting the board to land in the exact direction you’re heading, it will right itself.
Absorb the compression if you need to, then ride switch down the run-off until you’re completely back in control. Note that your board might want to keep spinning on the landing. To stop this, get that heel edge dug in once you’re pointing straight downhill, then get ready to turn the board back around (or even better, throw a cab 180 off the next kicker).
