Two new flies i've been using with good success have been a Hydropsyche and Rhyacophila imitation. Using them as a secondary fly to a lead attractor dry fly. Dabbed with some Frogs Fanny and away I go. The dry shake in-beds the dubbing and soft filaments with a coating that seems to create or hold tiny bubbles that add something that the trout turn on to. I like using the fine Gamagatsu emerger hooks for these patterns. Nice gap to hold large fish. Finer than average wire to add a tad of stealth to the profile.
