The "Roswell Wire Leader". Called that because Pandemonium Tackle just jokingly said they found this stuff on a UFO! It is a solid wire that is made from an extremely durable kink resistant alloy. They had it made in .034" dia. then they use the highest quality crimps, each meticulously lined up before crimping for maximum strength. We tested them to 130lbs and the cool thing is the wire will stretch 8% at about 60lbs and go back to its original shape. These leaders will take the abuse of multiple fish before replacing with no need to bend back straight. This 12" Leader has a swivel and is great for bucktails and tail rotating topwater baits. This is the 12" Length and has swivel.
