The leader is the most important item of your line setup. Throughout my life, I have used countless hours educating fly fishers all over the world about how important the leader is. The leader has been my main focus for many years. The leader is a mass that controls how well and how far you will be casting. It also determines how well your fly will be presented on the surface and how it will be fishing across the water. The mass of the leader consists of air-resistance and weight-resistance that have to be measured 100% correctly to match any given line weight and fly size. We are very serious about this responsibility.
