My versions (still in need of some trimming) of Bonefishdick's (yeah, look him up :) ) fly
titled "The Betsy"
There is enough info "out there" on Dr. Google for you to follow.
For now:
I also tied a black version.
These use ultra hair for the tail and collar, Farrar blend for the body.
Blue and White use florofiber for the throat.
Can't wait to fish them!
