I have been fishing with furled leaders that I make (wet or dry flies) for about 4 years now, wont fish without them. I make them from Fluorocarbon line for wet flies to Uni Thread for dry flies. If you have any interest in making your own furled leaders, you can purchase a DVD by Kathy for only $15.00 the DVD is called "Simple Furled Leaders by Kathy Scott” it is worth every dollar.
A friend let me barrow his DVD and this is how I got started making my own. The cool thing is you can play a D.V.D. on your computer and you can Stop & Play at anytime. Now in no way am I promoting this DVD, I just purchased one for reference only.
Here is some more information about Kathy Scotts furled leaders on the following website
