See Flies Through the Trout's Eyes - How Trout See Flies
Do you ever wonder why trout will take a certain fly one time and not another? Why will an attractor pattern sometimes work, and sometimes it doesn't? To answer these questions, we're going to metaphorically don our trout vision goggles, i.e. looking at flies through a trout's eyes by examining the trout's behavior and senses. One of the key points we will discover along the way is that you will be more successful fishing with specific imitations than with using generic or attractor flies.
