RE:Recipe For Fly At Top of Stony Brook Clave Link?
It's a good pattern to experiment with. The bait we are imitating does change it's coloration depending on the season and the location of the bait. We fished these with lots of deep green/olive and Rainbow angel hair as flash when we were chasing fish in deeper water off the beach. Juro used a version with a light tan / copper back and minimal flash when fishing the flats off Brewster and Monomoy.
The basic pattern is tough to beat. I use white streamer hair as an underwing to give it a little more action and less buildup than bucktail. Experiment and you'll like the results.
