The Prisma Leader 9' is the choice when a fluorocarbon leader is preferable to traditional nylon. Its density helps work the tip below the surface and reduces visibility in clear water. The special coating makes tying knots easier and improves durability, even though the material is stiffer than a soft monofilament. This stiffness maintains good line speed, which is useful when fishing with heavy nymphs or wet flies. The choice of line variant depends on the desired tip action and strength.
