Shilton set out to create a robust monofilament shock leader for conquering large powerful species, one that matches the Shilton ethos of great quality at a reasonable price. Shiltons shock leader came about because our R&D team could never quite get the right kind of leader required for GTs and blue-water species, one that is relatively supple and doesnt sink like fluorocarbon. It could not be too supple as soft mono attracts significantly more bite offs. The result is a stiffer mono with a diameter equal to soft mono, has great knot strength and a way better bite-off ratio. Shilton Shock Leader comes in at 50 meter rolls of 100lb, 130lb and 150lb and is reasonably priced.
