Your release needs to be on your rigger cable/line not the ball. When you load up your rigger rod if the release is on the ball you will change the way your rigger ball travels and get a royal mess. If you tried sliding another release down the cable while moving it will never reach the bottom with a line attached to it. When your rigger is up and the ball is just under the surface you want your release where you can get to it without the ball breaking the surface protects your boat and riggers.
