This variation on the Thunder Egg was Walter’s best steelhead pattern on small coastal rivers in Washington when he lived there from 2004-2006. It is really more of a “Great Lakes style” pattern: fast-sinking and quick & cheap enough to produce that you don’t worry too much when you lose one in the rocks.
The basic pattern also works as a trout fly, particularly when you’re trying to anchor something smaller and lighter, either an unweighted egg or a smaller nymph.
Hook: Egg hook #6-10, or scud hook #8-12.
Thread: 6/0 to match desired egg color, here light pink.
Tail: Two strands of pearl or pink Krystal Flash doubled back on themselves.
Eyes/Weight: Nickel brass dumbbell eyes. Desired size to match desired egg size. Original pattern used pink or orange-painted lead eyes.
Egg: Speckled chenille, here pink, wrapped in X-wraps around the eyes.
