I must agree on the " Over / under " system of coiling anything from electric cords , fiber optic cable , or any other cable or rope as it's the preferred method of coiling it for storage including home run cables to the trucks from the "shed " for camera work for whatever event you're working at .
On many occasions I've taught the art of over undering camera cable to crew members as it keeps what could be total confusion under control when you have a camera person who is a runner to get the required shots for the event .
If you were to watch the Billings PBR events from years past there's a good chance that you'll see me at work as a cable page when I'm not needed as a house camera op .
