I setup my 9" boone birds with a swivel on the back side so i can swap it out with any rig I want to pull behind it. My question is I've been seeing these setup with a mono jumper going from a hunk of mono crimped to the front of the bird to the hunk of mono that the swivel is crimped to. I'm guessing in case the bird breaks. I would think the bird has a wire right through it. Anyone else do this?
