Hoot's River Juan is a must have.  It is a great go to fly working everywhere. Landing Rainbows (even 16" wild McCloud Redstripe at Cranecreek M.O), browns at Beaver Dam Tailwaters. I love using it as a dropper with a double dropper or a dry dropper set up. Depending on water clarity and size of the fly, 5X-6X tapered leader and tippet are great choices.
