The Czech Competition Leader Hends combines a low-memory colored monofilament, a float, and a micro-ring leader. This design is intended for nymph fishing on long rigs.
The 6- and 9-meter versions are available in several diameters and rated strengths. Each option provides these three pieces of information: the length allows you to set up the rig with your rod, while the diameter and strength characterize the leader itself.
