It's ground up garbanzo beans, it was kind of a joke, I'm not going to bring it!?
Anyway, good buck tail is so darn hard to find. I open up the packages and feel each one, for the kind of jigs I tie, I look for the straightest, thinnest diameter I can find. There are also 2 good fly shops on Manchester Rd. Feathercraft and TJ Hargrove. They are close to each other near Brentwood and Manchester. But I still go to BPS and Cabelas too.
