Fluorocarbon leaders can be engineered with a varying degree of suppleness, rated ST1 to ST5, to perfectly match the fishing style and prevailing conditions. A fluorocarbon line with an ST1 rating is designed to offer maximum stiffness, providing excellent sensitivity and optimal control for precision casting and hook-setting.
At the other end of the spectrum a fluorocarbon line with an ST5 rating is engineered for maximum flexibility, allowing for increased knot strength and durability. Whether you need a stiff fluorocarbon line for finesse presentations or a supple line for improved handling, our range of lines with different ST ratings has you covered.
