Northern CA & ID Posts: 2604	Hi Silverexprs, Welcome to the forum! The answer depends on water type. On still waters I usually fish them deep with a short twitching retrieve on a long leader/tippet near weed beds. Some advise the occasional pause (as do the naturals), but I don't do this as my patterns are heavy enough that they sink too rapidly in an unnatural manner when paused. Use of sinking lines to obtain depth and the use of lighter flies would allow this, but I like the visual aspects of looking for the twitching leader. If there is a breeze making it difficult to see the leader (there often is with cloudy weather), I use an indicator and fish the fly slower as the riffle will apply some action to the fly. Capture samples for a given body of water to dictate size and color. A bug net swished in the weeds will bring up plenty of samples if they are present and available as a food source worth imitating. I use specialized imitative patterns to match the naturals. On moving water, I generally fish them dead drift. There are a few spring creeks where the more imitative flies are perhaps best, but I generally rely on the Zug Bug, Bird's Nest and especially a heavily weighted Sawyer's Killer Bug. Having said all of the above, IMO the only time they are worth fooling with are when populations actually exist in worthwhile numbers and when I'm on the water fishing during the low light of dawn, dusk or cloudy days. During the bright midday hours, they are buried pretty deep in the weeds and unavailable except to "rooting" fish. Best regards,

Northern CA & ID Posts: 2604	Sure do! I don't use yarn. After searching the world (or so it seems), never came across one that even comes close.:) So, I experimented & experimented until I came up with a dubbing blend that matches the heathered tan color with a pinkish cast about as perfectly as possible. I think it looks even better from a texture standpoint. Even if I had a skein of the old Chadwick's 477 (only have about six inches left, kept for reference), I'd still use this stuff. Besides, I could sell the skein on Ebay for enough to pay for a fishing trip! :) Dubbing blend - 50% Hareline hare's ear, 50% tan "Buggy Nymph", a smidgen of red angora goat You can tie the fly conventionally by using copper wire and starting the dubbing at the head and tying it off at the tail with the wire, but I use pink or tan 6/0 Danville's tying thread over 16 wraps of .020 lead wire (size 12 hook). Using copper wire in the tying as per Sawyer would work better on waters like the Avon I suppose, but I find this method more successful on our heavier western rivers. When you've covered the lead to the point that it's mostly hidden, apply the dubbing thickly and dub it tightly as possible with your fingers (about 3" or so). Do it in layers rather than all at once so you can build a tighter, more consistent noodle. Form a loop by hooking the thread below the dubbing with a spinning tool and wrap the tread around the shank a few times. Now spin it up tight clockwise if you're right handed. Wrap forward and tie off. It takes a few to get the amount of dubbing to apply, but once you do, it's the easiest fly in the world to tie (most guys tie them too thin, IMO). The photo below makes the fly look pinker and lighter than it actually is, but you get the idea of the texture and look of the finished fly.

Northern CA & ID Posts: 2604	Louis, Those two photos point out how different the same fly may look in different conditions - one photo wet and backlit (trout looking up?), the other dry and in the hand. In retrospect, I don't think this is due to camera aberration. Hmm... This may be evidence/example that Sawyer's speculation that his tan fly took on a pinkish cast to the fish when wet (due to a few red fibers in the yarn) and led to their excitement? Other examples of this phenomena are replete in discussions of fly color in our literature. A study of highly successful flies photographed wet and backlit vs. dry and in the hand would be interesting...
