Perdigon Trout Flies
Perdigone fish best in pocket water situations when you will be making frequent close-in presentations. Pocket water requires that the fly gets into the strike zone instantly while being suspended under the rod tip. During these brief presentations, the fish only gets an instant in which to decide if the item is edible or not. The only way for a fish to determine the edibility of objects drifting in these fast currents is by taking it into its mouth and tasting or feeling what it might be. The fish either ingest or reject the offering in less than a second. I have seen this behavior while snorkeling. In deeper pockets, bright, attractive perdigones get the fishes attention quickly, and through the mechanics of tightline nymphing, hook themselves on our sharp hooks in the act of inspecting the fly.
