I basically tie two versions. One version, the ones you have been seeing are my Gorge supply. They all start with 28" of Maxima Ultragreen #12. The trailer hook is a #4 and the main hook is a #2. They can be used either for spinners or hoochies and I have a combination of colors either tied with a single or double soft egg bead. Most of my everyday combinations are tied the same way only using two #4 hooks in tandem and #10 Maxima Ultragreen for the leader. Once the spinner or hoochies are done I simply wrap the line around two fingers 5 rolls and then put the tag end around the coil three times so they won't come unwound. Then I toss them into the bag. Depending on the dodger and the speed I'll tie a surgeons loop at the desired length at the time I put it on the rod. All of my leaders are eventually attached by this loop. My finished hoochie leaders are generally tied at 6 to 10 inches and my spinner leaders can be anything from 12 to 18" depending on water temps, clarity, speed and dodger type. Part science and the rest is just dumb luck.
