RIO's King Wedgewing Flies were designed by long time guide Jonny King. King has created an exacting wing to match mayfly profiles beautifully. The Wedgewing is so close to the natural you have trouble distinguishing your BWO or PMD or March Brown from the natural bug on the water. Using natural stacked hackle, synthetic yarn and CDC the Wedgewing sits up nicely so you can see it as fish gulp it up.
