I'm puttin my money on Lund...
I have found steelhead don't seem to care as much, but kings especially can get locked in on a certain egg cure. One day last fall we had three cures with us fished maybe four hours, fish completely ignored two cures, hooked 12-15 on the third cure, on other days sometimes it was a different cure. I agree pressured fish in Washington & Oregon can be way more picky on what kind of eggs they bite. We use to catch kings in AK on some of the crappiest eggs, the fish were simply less pressured and less selective. Unpressure steelhead in Washington/ oregon on the other hand couldn't care less what kind of eggs they bite for the most part.....
