I saw Fred's tutorial on his website last year. Even though my bullfrogs weren't anything near as nice, they did catch a lot of nice fish for me last year. The best part about this fly in my mind was that I could fish topwater any time of the day and expect to catch nice fish. I even had one fish come screaming over and smash the fly from over 10 feet away. Watching that v-line coming from so far away completely sold me on this fly.
It takes sometime to tie it but its well worth the effort.
