Gavin has tied these flies using the finest of Hackles , Schlappen and Marabou available. On GT Flies you need to use the TOUGHEST HOOK. There is only one and that’s an Owner AKI #8/0. The AKI has a tough corrosion resistant, black chrome finish.
Aki’s are designed with OWNER’s unique Cutting Point. When the hook penetrates the resistance actually decreases as the cutting point penetrates through.
