These leaders were designed along with help from Madison Wisconsin Musky guide Jeff Hanson. Jeff produces alot of fish using this type of leader year in and year out and finds them very crucial in helping him get his baits "into the zone" where they need to be in order to contact fish. Available in 1oz. They are approximately 12 inches long and built on a 240# solid wire leader. they have our stealth 150# Ball Bearing swivel and of course a always reliable #5 Stringease Stay-Lok Snap.
