I also like to fish from the meadows up to the Joss. And the fish DO strike a fly hard. But those same fish after two days will be in mid river areas and not nearly as aggressive.
I also will break off a foul hooked fish.....it's such a pain to be losing flys....and the salmon (after a week or so) start looking like grandma's pin cushion......adorned with all those breakoff flies, lures, etc.....it does get ugly!
Perhaps you are right....maybe the deep pools & stacked fish should be avoided altogether...(maybe protected?).
The issue becomes even more heated when it pertains to winter steelhead.
It's a tough one and thanks for your input.
Congrats on getting into those early Kings.....they do fight hard!
