This monofilament leader was developed for Czech nymph techniques. Its tapered, knotless construction measures 4.5 m. The extra-flexible material has minimal memory, allowing for precise presentation of delicate flies. The transparent and camouflage versions range from 0.20 to 0.35 mm, while the two-tone version ranges from 0.20 to 0.50 mm. The breaking strength is 8 lb or 3.6 kg. The transparent version remains the most neutral, the camouflage version breaks up visual continuity, and the two-tone version makes it easier to track; be sure to select the diameter range that best suits your fly pattern.
