My best snook fly is perhaps one of the simplest flies ever -- the D.T. Special (variation). When I first started sight-fishing snook in the surf, I used a Lefty's Deceiver. And it was effective.
However, Matt Hoover, a guide in Naples, Fla., sent me a D.T. Special and told me it was the only fly I'd ever need for beach snook. He was right.
Over the years, I've tweaked it a bit to suit my needs. I place four neck hackles at the rear of the hook and they face each other. On the original D.T., the feathers are splayed. Reason I face them is so that the fly sinks just a little quicker. I also add eyes and epoxy the head.
