Hydropsyco and Rhyco Rat
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.
