USO (Unidentified Sinking Object) Nymph
This is a favorite of ours to tie and fish. We enjoy it so much because it is such a visually stunning pattern, quick to tie, and deadly effective. We love the darker colors in the wintertime combined with a metallic bead to garnish attention, but it will work in a myriad of color combinations to your hearts content. We fish it as a searching attractor nymph, or in color combos to match Mayfly Nymphs in a variety of sizes from 12 through 16 on your favorite jig hook and slotted tungsten bead.
We love fishing this in a two fly set up as an anchored fly with an additional nymph, or a trailing soft hackle so we can hit two different depths of the feeding zone. We love how effective jig hooks are for attaching a second fly to the eye of the hook giving both flies excellent movement. With the Semperfli Krystal Flash legs this fly will have great movement on a dead drift as well.
