PM I think that there are several reasons why salmon fly fishing has not caught on out west here.
1. Salmon come in during some of the best steelhead fishing of the year and steelhead are 10 times the gamefish as any salmon.
2. Salmon rivers out here are almost always too crowded leaving no room for flyfishers
3. the people who do is successfully are very tight lipped about when and how because the fisheries are so crowded.
4 people don't own the 11-12 weight flyrods necessary for chinook fishing
5 we spend all winter throwing heavy sink tips and when June comes around we don't want to see them again until December.
I think the main thing is though that our best steelheading occurs at the same time as the Salmon fishing
Only steelhead matter!
