1/80 or 1/64 oz. Grouse Fly here to start with and then if that don't work I go to a Little Pinky....1/64 pink/chart combo....and if push comes to shove I get in the secret box I keep in the bottom back corner of the big box and get out the KILLA'....Custom Painted head and tail combo that it would be dangerous to let out on the bream community......:D
