In a swap box a few months ago, I acquired a package of Spanflex material, and just found a neat-looking pattern called the Spanflex Buzzer, tied on a scud hook. I want to tie some of these, but I have no idea how to fish them. I've been fly fishing for over 40 years, and have never used a fly like this (I grew up in Texas, where most flies are big and mean...for bass).

I am guessing you fish it like a nymph, but I am not sure. can anyone enlighten me?
