Lots of great advice here. Personally, fly fishing for steelhead has a lot of parallels to golf. Sometimes when things are not working I have a tendancy to overthink the game. When I get into a stretch like this on the river or the golf course, it helps me to dumb everything down and just stick with the basics. It improves my confidence to stick with techniques and bugs that I have been successful with, and largely ingnore the subtleties of conditions. Fish with confidence that each cast could be the one. I have caught fish on big gaudy bright bugs that conventional wisdom might consider a no-no in clear low water conditions. I fish those because I have confidence in them, and it tends to keep me focused on presentation more than picking the correct pattern. Maybe I am just lucky, or inexperienced, but it works for me.
