Leaders&Tippets

This small article is a selection of questions and answers about leaders and tippets accumulated over the years. Martin Joergensen has harvested the most popular questions with the assistance of his fellow GFF partner Steve Schweitzer.

Production leaders

What is production leader tying? Tying more than 2 leaders at a time! But, if you are like me, you find out that tomorrow you may go fishing, so you scramble to tie just enough leaders (usually 2) to handle the day and go on with life.

Making loops

These loops are often refered to as Orvis loops. I don't know if Orvis invented them, but they do sell them -- and at high prices too.

Making a loop directly on a fly line

This is a way of making a loop on a fly line that will give you a very neat and tiny loop and a smooth transition between the different parts of a rig.
