Run the stops back to back. I run 4 stops on my ball. I have two of them set together so the ball stops while still in the water so it is not swinging around when in rough water and another set of stops so the ball stops about 2 inches below the pulley. These are also used as backup stops. I have noticed that if the is a lot of garbage in the water the stops will sometimes slide through undetected, (I have lost balls this way). You can also by a pulley from Scotty that will not allow the cable to jump off track. The stock pulley on the end of the boom is next to worthless. Any slack given to the cable and it is instantly wedges itself between the bolt and the pulley.
