the McKenzie River near Eugene, Oregon, USA is a fabulous fishery. My best results using a Shark's Caddis Larva is when I used the hare dubbing sparingly. I have a tendency to use too much material.

Rado - How do you organize your fly boxes?
I evolved from wet and dry boxes to location boxes; (places I frequently fish). Now I organize boxes for specific insect species. Example: Blue Winged Olive - dry, emerger, and nymph patterns in multiple sizes and color. On my label, I note time of day for hatches and type of water habitat as a reminder to myself. I found this to helpful in selecting an appropriate pattern. What do you do?
