Allowing the fly to sink to the fish's level, the angler makes a retrieve. The fly comes directly at the fish, which suddenly sees its approach. As the small fly get nearer, the fish moves forward to strike, but the tiny fly doesn't flee at the sight of the predator. Instead it continues to come directly toward the fish. Suddenly the fish realizes intuitively that something is wrong(its never happened before), so it flees until it can assess the situation. An opportunity for the angler has been lost.

I personally feel that parachute files give a more realistic impression of an insect to the fish that views the fly, since the hackles are in the same position as the insect's legs, and when tied with brightly colored hackles, these flies are easier to see on the float. A final advantage is that in rough water, a parachute-hackled dry fly will float longer and better than a conventional one

Trout fisherman often give away their presence to the fish by the equipment they are wearing. The yo-yo hanging on the fly fishing vest that attaches to the hemostats or line clippers is often plated with chrome, giving off flashes of light. Some fly boxes that you wear on the chest are also bright aluminum-not a good idea. I recently fished with a fellow who wore a bright yellow hat on a meadow stream in Pennsylvania. From 100 yards away you could see his every movement,-I'm sure that trout near him could, too.

There's more B.S. in fly fishing than there is in a Kansas feedlot.

It is not a good idea, either, to attach material such as Krystal Flash or Flashabou, then trim all strands at one spot. This gives most of the reflectiveness at one location - where the strands were severed. Instead, clip off the strands at different lengths along the entire body - that way you'll see little sparkles of light throughout the pattern

Most fishermen use the double haul to throw their casting mistakes further.
