Leader Formula.

Those that fish with us know we are big fans of hand tied leaders. Most agree that the performance is better than store bought extruded leaders. A really good formula we use on small streams is listed below. For butt and mid sections we use Maxima Chameleon. For tippet we like Rio Powerflex.
This is a stiff leader that will help drive a bushy dry fly in tight quarters. It can also handle a small beadhead dropper. Allow a little extra butt material if you prefer a nail knot or a blind splice connection.

Don't worry if your off an inch or so. The leader length should be about seven feet. If you feel that the sections need to be exactly as listed you have entered fly fishing geekdom.
