Okay, so TS BS 720 has a lot of letters and numbers in it, which means it's effing hard. To our knowledge (which we take some pride in) this move has never been completed. Shane landed it on Sunday at Brostock on Lake Oroville in Northern California. Apparently you should have been there.
Rumors are that there is a sequence of the move, but Shelby Kantar's hand is in the last few frames as she was pumping her fists in jubilation, right in front of the camera.
