I find that methods are easiest off heel side hip jumps, natural or in the park, the shape of the jumps puts your body in the right position. The whole thing pivots around your front leg, pull your front knee in and reach for the grab, then push the back leg out, at the same time rotate your upper body.
Grabbing in front of your binding or behind is a style choice, euro vs NW. Got to have your back hand up arcing over your head. In my avitar pic I'm almost grabbing my rear binding.
