20 Incher Stone
The 20 incher is a phenomenal fly in its standard form on a variety of Colorado rivers (Lower Blue, Arkansas, Roaring Fork, lower South Platte, Eagle River, Gunnison River) that contain populations of stoneflies and green drakes. For tailwaters with Green Drake hatches (Frying Pan, Taylor, Blue) and more selective fish, tie the 20 Incher without a bead and color it black with a sharpie to match the Green Drake Nymph.
