OUR FAMOUS F-C "LUCKY-DOG" Knotless CoPoly-Mono Tapered-Leader "BUTT-SECTIONS" FOR TROUT RODS are the favorite of thousands every year. The butt (top) is a custom-fast taper for fast easy turn-over of 3x to 8x tippets. Length is 7-feet, with LOOPS IN BOTH ENDS (unless requested without loops). The copolymer-nylon material is "tempered" for long-lasting durability. Tippet saving stretch built-in. After storage on reel, simply hold it slightly stretched and count to six. The leader will be ready to fish. Designed for 4-wt thru 7-wt lines. Attach loop to loop, or nail or needle-knotted to fly line. Then attach 24-inches of tippet material to bottom end for an overall 9-foot leader system.
