I've had real good luck with a glass bead caddis that uses 3 green beads for the body and an amber bead for the head. I tie some mohair between the first and second bead and some thread at the back end to keep the beads in place. It works great on pickerel.

" Fishermen, hunters, wood choppers, and others,
spending their lives in the fields and woods,
in a peculiar sense a part of Nature themselves,
are often in a more favorable mood for observing her,
in the intervals of their pursuits,
than philosophers or poets even,
who approach her with expectation."
Henry David Thoreau
