I adjust accordingly to the mood of the fish. If the fish are real active and are attracted to the hum of the rigger cable I will have them tight to the ball like 10ft. Like Mike C said you don't wanna run them too far otherwise you'll get a tangled mess. So about 40ft lead length is the max for me when running flashers. If their still not hitting that then I rely more on dipseys, leadcore, wire, etc....
