Big toothy critters love to slam this fly. Be it a Pike in Alberta, a GT at Christmas Island, a Barracuda in the Keys, the axiom of "big fish = big fly" carries weight.
This fly could also represent a young Dorado and entice that monster Billfish to strike. This is another great pike or musky fly, or even throw it at Peacock Bass or Golden Dorado. It is willing to be eaten by anything. Just look into its eyes. That is fear that you see.
