@Fred those are beauties fo' sho'!
If you haven't tried Borden Specials for the Bluebacks (sea runs)...get some. Developed decades ago by legendary Oregon fisherman Bob Borden. This is what they look like (pic below taken from the Caddis Fly Shop site).
Bluebacks also gobble up Rooster Tails with brown bodies and gold/brass blades. Because they mimic a major food source: crawdad babies.
