Dennis Potter is a widely known Great Lakes fly designer. The Opal-X, a spin off
from Craig Mathews X-Caddis has served us well. The body appears a red color
here, but don’t be fooled. This is simply a camera lighting issue. The body color is
pearl. Dennis fishes this fly whenever caddis are present. It out-fishes every Elk
Hair Caddis out there...period.
