Use a 4X tapered leader off the butt section for bigger dry flies like Skwalas, and hoppers. 5X for small mayflies or caddis. This is the same leader I use for sub surface fishing in shallow water at Lake Davis and Frenchman Lake, especially during the damsel hatch. The stiff 40 pound mono turns over efficiently delivering your fly to the intended target accurately.
