Some interesting flies however you might consider some smaller verisons as well. Over the decades my most effective flies for both coho and Chinook have been smaller than want many folks use. The majority of my success on Chinook and coho has been with size 4 flies though will step up or down a size or two depending on the situation. Also very rarely use weighted flies

My personal best Chinook was a 51 inch beast that took a size 8 black woolly worm variation. And yes I was targeting Chinook when I caught that fish - one of 15 or so I took that day while my wife added another 1/2 dozen (including her personal best of more than 30#) while taking turns with my fly rod. All those fish were caught on various black marabous and wooley worms size 4 and smaller. While black was the color of the day on that trip other times olives, oranges, etc were better choices.

Have had similar success on various PS river coho with smaller flies - pattern of choice would be #4 Knudson spiders in various color combination.

In short there seems to many ways to attack the salmon fly fishing game.
