Great. My husband and I tye flies. He works for the company that manufacturers and distributes for Orvis. I have access to any flies I want, I have boxes full cluttering my sling-pack and kayak bag. I go out with the full intention of using different warm water flies but It seems I always end up with a "little fatty" on my line. Sizes 4/6/8 depending on conditions and what rod I'm using. I've gone to mostly buying/using white and if I want another color I pull out a sharpie. Drives my husband nuts, we have been teaching FF for NH F&G for over 20 years and he says I am passing on bad habits. But my students catch fish, I just wish they would not lose so many of my precious fatty's.
