Rig Rings are a wonderful addition to a Rig when trying to create a very dynamic Hair Rig presentation often referred to as a Blow Back Rig.
The addition of a Rig Ring allows the Hair to pivot and move up and down the shank of the Hook, giving greater movement for the Hook to flip underwater and catch hold in the fishes mouth.
