This is a wakestyle biggie because of the fact that its a powered handle pass trick. You're going to need to have your front rolls and basic handle passes down for this trick. Nailing a few frontside 360 handlepasses first is always a good way to warm up. The Key is getting your legs are high as possible to help you with the pass. When you're nailing these feel free to describe yourself as a darn good kiter.
Note: The S mobe is often referred to as an NIS which stands for a non inverted slim. A 'slim chance' is a fully inverted S mobe.
Ride fast, Kite at 45 and unhook
Pop a colossal front roll. Literally the biggest you can do from a straight pop. Throw your head and your weight over the back shoulder.
As you legs come around (completing the frontroll), pull hard on the bar
Throw your weight over your shoulder and let go of your front hand and look over your front shoulder. This shifts the momentum so that you can begin your spin in the other direction.
Thrust those hips towards the bar and hold on with all of your might as this is a tough pass.
Still looking over your shoulder, pass the bar and pull into your hips again to help you balance.
As you complete the pass, spot your landing and makesure you land downwind. Due to the forwards nature of this trick prepare to land fast. Saying that, because your legs are dropping down it makes for a relatively easy landing in comparison to other tricks. Sick!
