Nismo: what do you mean with a halo loop?
I didn't see Kevin doing a front and back 360?
I do up to 4 rotations no handed with a double board grab...a stopper or Microloop is needed.
And a kite that is parked in zenit, no where else!
Again, a slow !!! Kite will make you land it, an fast turning kite most likely send you to hospital.
15 knots with an 18 is 1000 times safer than 30 with a 9...
The liftoff and initiation is basicallly the same as a normal rotation jump, just once you start to spin you lock the bar and keep the momentum.
Open up your body to slow it down again.
See here at 0:54 the Front 1440 Double Grab.
