Rocky’s Pullin’ Shanks are part of my quick change system. It allows you to fine-tune your baits. It lets you adjust your bait to run in the zone. It comes with three clevises spaced 6″ apart, so it can be used as an adjustable 3-way rig, for rivers & an adjustable bottom bouncer.
I usually run a 4-6′ (feet) leader off a ball bearing swivel attached to the clevis. A vital part of the system is the weight. Your weight should match your speed or the current. You always want to keep your line at a 45 degree angle maximum.
