Coffin Caddis
How many times has your fly sunk before it reached the fish or won't float in the riffle where all the fish are rising? With this fly, you can even intentionally pull under and it'll pop right back up. In fact, a deadly way to fish is to use this technique to imitate an egg-laying caddis. Use a bit of floatant to really make it unsinkable.
This extremely effective pattern gets its name from the shape of the foam before it's tied in.
