The Strike King Tour Grade Tungsten Carolina Rig Weights are designed specifically for the Carolina Rig technique. Tungsten's density makes it much harder than lead so you can feel the bottom and detect strikes much better. These are internally polished to eliminate line fray, shaped for less hang ups and to minimize damage to glass beads.
