Tungsten bead head kebari sinks fast and is a great option to bring your fly down to the fish hugging the bottom. This is what Brent likes to use these faster sinking bead heads to ride the bottom of the water column. This fly has a 2.8mm tungsten bead.
BRASS bead head kebari sink slower but still have that flashy bead head. The BRASS bead head is what I see Tom Davis using most of the time, he is not looking for it to sink super fast but wants the shiny bead head pattern.
This fly pattern comes from a fly I have seen Tom Davis mentions he uses in the article "The Marvelous Bead Head Futsu Kebari" and I have found it to be a good producer in deeper runs or during non-feeding times of the day.
Tied on a high quality size #12 Short Shank Moonlit hook.
You get 12 flies.
Casting bead head flies on a tenkara setup needs to be done right as they can damage your rod if it hits your rod, see the article "Safely Casting Beadhead Flies on Tenkara Rods" for instructions if needed.
