Bead heads?
I don’t like too much bead heads flies but i recognize they are effective.
It is interesting to me use them in deep pools where the current is minimal.
After their sinking, I retrieve line very very slow with attention focused in the tip of my floating line where brookies report their presence.
They’re nice for getting to the bottom of deep plunge pools!
Utility over aesthetic!
