The leader is made from Uni thread in sz. 6, light yellow in color and tapered correctly to the weight of the rod it is used on. I don't know much about them but plan to learn. I know they last longer than a regular leader and can last a couple of seasons if taken care of. I'm just trying to find out how to take care of them. I'll be using it for Bluegill, Crappie, and White Bass.
