I've always used the thread type but they start to slip after a dozen or so fish are caught. This past weekend I tried the ones on the left of this pic and they slipped on my first crappie I caught. I'm using 8lb test line. Anyone know of a good stopper that won't slip? Many years ago I remember my Dad tying rubber bands to his line, what a pain.
