Brush flies are one of the most common GT flies and have seduced countless fish! Once in the water, you start to strip as fast as you can and hope for the big bang. Have fun fighting these bulls ;-)
Besides GTs you can of course fish for any other predators like barracuda, bluefind trevally, snapper etc. and freshwater species like pike will love these flies as well!
Tied on a Gamakatsu SL 12S, one of the strongest and sharpest saltwater hooks out there.
