If you are interested in tying your own Light Cahill flies, see our fly pattern recipe below. Color, Light tan.

Rated 1 out of 5 by from Horrible There are more then a few great quality flies to be purchased at Orvis. These are total garbage, inconsistent tying, bizzare clor differences in the same batch, the wings are all banged up. Beyond poor quality. Purchased 20 of them. They looked like they were tied in 3 minutes.
