It's a decision we make every time we approach the water. You've done it hundreds of times, yet we still struggle with the decision. My first instinct is to match what?s flying around, be it a major hatch, or just some local everyday caddis. No insects seen, no trout rising, my second choice would be an attractor. This is the mental conditioning I received from years of reading trout books and magazines. Your methods of fly selection are probably different then mine, and the method by which you were conditioned may be different then mine. But we all still go through the mental process. How often has your first selection of a pattern been so right that you fished with that pattern all day? A quick browse through my fishing log reveals to me that I switched patterns as many as nine times in one day.
