Sunline System FC Shock Leader Fluorocarbon 100% 

A FC leader who can persevere in battling fish near rocks and other structures. High sensitivity and resistance to abrasion. The design makes it possible for your jig or lure to perfectly transfer movement in order to hook a fish. Its smooth and resilient qualities allow it to tolerate significant impact even though it is made of fluorocarbon. The knot strength is really strong. Damage to the line surface is reduced by parallel spooling.
