I just started making these, and so far I'm thrilled. Simplicity at last!! I live in central NC and fish both fresh and saltwater, and not a single fly shop for 200 miles. For years I've just bought extruded leaders, or went the blood knot route. Both of these are costly and require an inventory. Curiosity killed the cat, and I searched for a "better way". It never occurred to me to twist some mono and make a tapered leader out of it. I can probably get away with a cheap spool of 4# and 14#.... and make leaders for years. I'm sure I'll find the drawbacks with time. But, for now I'm thrilled I don't have to order supplies online and hoping I'm getting quality materials. Anyone doing the same, or have experience using twisted leaders?
