A good bump rig starts with a B'n'M 3-Way Bumping Swivel designed especially for this stationary technique in which you slowly ""walk"" a bait rig downstream with the current, bumping the bottom all the way. It's incredibly effective, and this super-tough, flexible 3-way swivel does a great job of keeping your line, leader, and dropper properly positioned at all times. Also great for many 2-way applications. 3 pack.
