Our GT fly is tied on a super stong, super sharp, 600SP hooks is size 3/0. This fly is unweighted, but due to the size and heft of the hook has a slow sink rate. Our pattern combines maribou over ginger and white natural and synthetic materials for both lifelike movement and durability. While these are candy to GTs, they'll work for lots of agressive predator fish you might encounter with a fly. Try 'em on Pike, Mahi, Jacks, or big Snappers.
