Tin Foil Time
Big flies, spoons, twitching jigs and bait - in order of increasing effectiveness. I've had reasonable success with flies in the Skeena area, much less success and much more frustration down here. The closest thing I have to a confidence fly for chinook is a bigger, longer winged and flashier version of the fly below tied on a tungsten tube. I use the longest fox I can find or sometimes Himalayan goat for the wing. I tried rabbit which I like for steelhead but it the fox/goat sheds water and makes for easier casting with the already heavy fly.

For the hatchery run I normally fish, I prefer to float fish with a centerpin. From a technical perspective (doing a bunch of different things quickly with low margin of error), I find it more difficult and more rewarding than swinging/jigging big flies and long heavy tips. But I also just like float fishing with a centerpin and it suits the water I like to fish better than swinging. You are free to execute your hazing strategy on me in the unlikely event we're on the same water. I'll respond by farting in your general direction.
I just signed on to a trip to Kodiak to target them this year which will be in shallow water with (what I'm told) are aggressive fish so lighter tips and all flies. in addition to the spey rod, I'll probably pick up a heavier one-hander and try some smaller flies up there for the helluvit.
I had pretty lights out fishing in Kodiak with a single hander, floating line and small pink and chartreuse comets with large lead eyes. Out fishing everyone with that setup. They really were aggressive chasing down on a pretty fast strip. The rivers are small and everyone is throwing giant vibraxes or baby fist sized gobs of eggs. The little fly was totally killer. I was fishing a 6wt since I broke my 8wt but an 8wt would have been nicer. There is no where to run for the most part unless you fish the last pool or two before the ocean. So I can’t picture needing very heavy gear and for the most part, you are looking at 8-12# Kings but there are definitely some big ass fish in those little rivers. I hooked fish north of 20# and have seen much bigger. Have fun kodiak is special.
