I use this
as a go-to fly when nothing else is working and I’m in danger of being skunked.
Normally I fish with size #12 flies but I carry this one in sizes #16 and even #20. This
unweighted wet fly imitates nothing in particular but represents everything
from a black gnat to a small stonefly nymph. It is tied with the softest Indian
saddle hackle, which will pulse enticingly in the current. On those days when
the fish are hesitant and not responding to my usual kebaries, this little
unassuming fly sometimes provides excellent results.
Hook:
any, size #16
