What river(s) will you be fishing?
That would help us out a bit.
One thing for sure these fish are real brutes, a 9w rod is a mandatory piece of gear. Add some 10-12# maxima green for leaders and you are set.
I have had my best luck with dark flys, black, purple, and olives seem to work best for me anyways.
Resist the temptation to run your fly thru the pods of fish, you will foul 99.9999% of them. Fish the darker water below the pods, you will be suprised with fresh run kings, browns, coho, or even a steelhead or 2.
