This 2-hook system is faithfully reproduced by Haruhiko Murakami, and is compatible with the decade-sized mushroom. Type1 11.8 - 13.8 inches (30 - 35 cm) long leader (Harris). The step design allows you to aim at the bottom and middle layer at the same time. Type2 7.9 - 10.8 inch (20 - 25 cm) short leader (Harris) creates tricky action according to the rod work, and reacts the bitter agne. As a jig head, the "leveling head ball-shaft hook" is standard equipped with a free knot. Ready to use with weights so you wont miss out on time. In addition, the long package prevents the leader (Harris) from becoming addictive and rotating beads that are difficult to twist and make it troubleless.
