Ok guys! Toddfather's back to work putting in long hours and haven't had much spare time which accounts for my absence on the forum!
Briefly, Making furled leaders is a simple process that defy's clear explaination however. Making them consists of two seperate strands of thread (cotton, polyester, unithread, nylon, kevlar, flurocarbon, mono, etc wound on dowels anchored to a board. Each strand is made by connecting the loops in an interlocking fashion. After both strands are ready, each strand is twisted seperatly with a drill motor with a hook in a clockwise direction until the length of the strand shortens by approx 10%. After both strands are twisted (cw)they are joined and counter twisted (ccw) until the original length is achieved. A drop of super glue will keep the strands from untwisting until the preferred termination is implemented. The above explaination is over simplified and there are a few small details that make things go smoother but have been omitted for clarity.
Seeing is believing, you'd be amazed how simple the process is. It ammounts to making a rope on a taper. The taper is controlable, and the leader properties can be change to suit varied fishing conditions notwithstanding the finest tuning of your terminal equipment.
You can design tapers that will turn over with tremendous authority or softness as required. No spay contrary to some opinions. Almost no microdrag. High visibility. Sink or float as required. Able to handle very long tippet sections, and the list goes on. Admittedly, some people just can't seem to buy into them for whatever reason. Personally I believe the proof is in the pudding, and I fish nothing else. Actually once you use them it's hard to go back to anything else!
