I tie a lot of bombers on salmon hooks in the 1/0 range for coho. They do not catch as many fish as other patterns, but they are almost always the most memorable fish of the day… A little foam might not be a bad idea for getting them to stay on top… and still look like a traditional fly.
Bombers are one of my go to patterns for smallmouth bass, let them skitter down-stream and across on a tightline and hang on.
I love this pattern with the added foam. Your solution of using the dubbing loop is brilliant. Spinning deer hair on foam is difficult - I would probably go with a bunch of stacked bunches but that adds to the tying time.
