Designed specifically for leader and top shot applications. The FC Leader uses Sunline's E3 raw material that makes the perfect balance of tensile, knot strength and stretch for optimum leader performance. It also features Sunline's Triple Resin Processing (TRP) for better abrasion resistance and improved knot tying. This line is 100% Fluorocarbon with 1.78 specific gravity and low water absorption for negligible strength loss under water. The perfect leader to match up with Sunline SX1 braid. Available in 50 yard spools.
