The Tuna Profile as the name suggest is designed for our Long Tail Tuna. The fly cuts the air like a knife, able to be delivered quickly to fast moving Tuna without the worry of fowling. The hook is well exposed for maximum hook up rate. Flies tied on circle hooks has worked well with most fish being hooked in the jaw hinge allowing it to be released unharmed. I like to tie these fly’s three or four inches long for Tuna however we have tied them six too eight inches long on 6/0 and 8/0 hooks for Giant Trevally they work very well.
