I decided to use a nonslip mono knot as the focal point of the leader. This knot provides almost full line-breaking strength when tied correctly. It's also very unobtrusive, streamlined and easy to tie. Begin by tying the nonslip mono knot in a length of line, leaving a large loop and 2 to 4 feet of straight line. Making the braided-line portion one-third of the total leader length works fine. For example, if you desire a leader of 6 feet, with 2 feet between each fly, the first portion of the leader should be 4 feet, and thus the loop on the first portion would be about 2 feet and the straight line section leading to the first fly 2 feet.
