The SWFA Eye Fly is mainly a daytime fly which works equally well for both offshore (baitballs) or the flats.
For species actively feeding at the surface, cast to the area where fish are feeding, or cast to individual fish if possible. Retrieve steadily with a medium speed. In areas with heavy current, try a dead-drift presentation or cast across the current and let the fly swing...this can be deadly at times. If fish refuse your presentation, try a different color, vary the speed of the retrieve, or add a pause between strips. This fly resists fouling during rapid-fire casts to fish like Tuna, making for perfect presentations cast after cast.
