Trick starts like a layout somersault. After leaving the bar, perform a double somersault with a half twist before opening to catch the stick. Half twist can be performed: Going into the first somersault ('Half in') Coming out of the second somersault ('Half out') This trick can be performed straight, tucked or piked.
