Varivas Nylon Shock Leader is one of the most popular leaders available for heavy tackle popping and jigging. The shock leader has a good amount of stretch to absorb the shock from violent attacks from big hard hitting fish such as GTs. Its supple nature gives it great knotting ability and strength. FG and PR knots also bite into the leaders surface perfectly for a strong connection to your mainline. The Varivas Shock leader has great abrasion resistance so you can be confident during long drawn out fights.
