Trick starts like a layout somersault. After leaving the bar, perform a double somersault with a one and a half twists before opening to catch the stick. Twist can be performed: Full in first somersault, half in second ('Full in, half out') Half in first somersault, full in second ('Half in, full out') This trick can be performed straight, tucked or piked.
