This story begins in 2011 when I made a three day trip to the Conejos River. I chose this destination since the northern portion of Colorado was locked in an exceptionally long snow melt that year. After an afternoon on the lower river near Aspen Glade Campground with minimal success, I paid a visit to the Conejos River Angler fly shop and asked for advice. The store salesperson directed me to the upper river below Platoro, and as is my custom, I purchased some flies in exchange for information.

The salesperson suggested some flies, and his guidance included salvation nymphs and green drake dry flies. The dry flies were the bushiest imitations I ever saw, and in fact they struck me as olive bodied stimulators, but they produced some very nice fish that day and the next day on the upper Conejos River. I deployed these green drakes on numerous occasions subsequent to the purchase, and they seemed to perform best during the initial stages of green drake emergence periods.

During July of 2015 I made a return visit to the Conejos River and camped at Lake Fork Campground in close proximity to the upper stretch where I experienced stellar success in 2011. Once again I knotted the heavily hackled green drake to my line and enjoyed splendid results during the late morning hours on two successive days of intense fishing. Of course extended usage of a fly exposes it to loss, and I depleted my supply of bushy green drakes to two bedraggled versions in my front pack.

I resolved to tie some more, but I did not know what they were named. Fortunately our modern state of life offers a tool for such a dilemma, and it is called the internet. I typed hair wing green drake in my browser, and I was pleasantly surprised to observe results that included Harrop’s hair wing dry fly. I scanned the images on the screen and rejoiced when I spotted a green drake that matched the two remaining flies in my possession. I continued my search and found tying instructions for Harrop’s hair wing green drake and printed them.

I am pleased to report that the step by step instructions were superb, and I cranked out five size 12 Harrop hair wing green drakes. My versions appear to be slightly more sparse than the purchased varieties as they possess a narrower abdomen, but my intuition says they will be productive additions to my fly box. The newly completed flies are slotted in my boat box, and they taunt me every time I spot them. I can hear the siren call saying, “You have seven months to wait before I can torment large trout and entice smashing top water takes.” That may be true, but at least I no longer worry about depleting my supply of these amazing fish magnets.

Light Gray Comparadun 12/27/2015 Photo Album

Up until several years ago the light gray comparadun was my preferred fly for matching the pale morning dun hatches that are prevalent in the western United States. I was always perplexed by the effectiveness of this fly since it possessed a light gray body yet most of the specimens I collected displayed light yellow and even cinnamon bodies. Despite this misgiving, who was I to argue with fishing success? I hypothesized that the light gray poly dubbing contained strands of yellow fibers, and this explained the positive feeding habits of targeted trout during a PMD hatch.

The light gray comparadun was so effective on the Colorado River near Parshall, CO that I encouraged my friend Jeff Shafer to tie some prior to a trip to Colorado. He asked me to take a photo, and I used the margin of a page of the Wall Street Journal as the background. We both felt that using a newspaper that documented financial results was suitable given the effectiveness of the light gray comparadun, and we jokingly nicknamed the fly the money fly.

Unfortunately change is a constant in fly fishing, and I began to encounter situations where the money fly failed to entice feeding trout during pale morning dun hatches. Exhibit A for this circumstance was the Frying Pan River where I endured several outings when the light gray comparadun left me in a disillusioned state relative to my dependable comparadun. Fortunately during a September trip in 2013 I stumbled across the cinnamon comparadun as a more effective imitation for the feeding inhabitants of the Frying Pan. In addition to body color, I also downsized my flies to size 18 instead of the previously favored size 16.

My conversion to size 18 cinnamon comparaduns has not caused me to totally abandon the light gray comparadun. I continue to find scenarios where the light gray money fly performs at a high level. I can only theorize that different river systems harbor pale morning duns with different shades of PMD body color.

I reviewed the status of my light gray comparadun inventory and decided to tie an additional ten in size 18. These have been completed and added to my fly storage container. These flies should enable me to test whether size of fly or color explain the change is success from the light gray to cinnamon comparadun. Stay tuned.

CDC BWO 12/24/215 Photo Album

I do not have much to add regarding the CDC blue winged olive that I did not previously convey on my 03/11/2014 CDC BWO post. This tiny fly continues to be a must have for my fly box throughout the season.

On November 23 I visited the Arkansas River tailwater in Pueblo for the first time, and I was lucky to experience a fairly dense blue winged olive hatch during the afternoon despite a clear blue sky. My size 22 CDC BWO produced three fish during the early stages of the emergence; however, it was largely ignored during the peak activity. I was in a prime position next to a long pool where at least twenty fish fed aggressively on tiny blue dun mayflies, and yet aside from a few temporary hook ups, I failed to land any fish.

Size 24

Near the tail end of the lesson in frustration I seined the water and inspected the specimens that appeared in my net. I estimated that the mayflies were a size 24, and this probably explained my lack of success. I vowed to tie some size 24 CDC BWO’s, and I fulfilled that pledge during the first couple weeks of December. I tied ten minuscule blue winged olives, and then because I was not satisfied with the look of my carryover size 22’s, I manufactured ten more.

CDC, Microfibbets and Size 24 BWO's

Despite its small size this fly is fairly easy to tie as it only involves three materials. The most challenging step is sizing the clump of CDC that is used to form the upright wing. I discovered through experience that an optimal amount of feather is necessary. If I make the wing too sparse, it mats readily and does not present a viable wing imitation. In addition once it gets wet it is very difficult to fluff back to the desired thickness. If the clump is too thick, the fly does not present an accurate silhouette, and the fish ignore it. In order to counter these difficulties, I strip CDC fibers from a feather and roll them into a clump. I gauge the thickness for proper bulk by focusing on the area just above my pinch because this section does not contain air spaces and more accurately portrays how the wing will appear once tied to the hook shank.

Cinnamon Comparadun 12/23/2015 Photo Album

Up until several years ago, I relied primarily on size 16 light gray comparaduns to match the pale morning dun hatches in Colorado. During a trip to the Frying Pan River in September 2013 I encountered a heavy pale morning dun hatch, and the light gray size 16 comparadun was soundly rejected by the educated fish in the upper tailwater. Fortunately I searched through my excessive number of fly boxes and discovered some old size 18 comparaduns that I tied for the Dolores River. I blended light olive and maroon dubbing by hand, and these flies not only saved my day, but they produced spectacular results.

Of course this experience prompted me to produce some newer versions, and I purchased a bag of Hareline cinnamon dubbing for this purpose. In the two years since the Frying Pan River success story I tested the cinnamon comparadun on the Eagle River and Yampa River along with the Frying Pan River, and it delivered solid results in these additional settings. These encounters with positive results using the cinnamon comparaduns convinced me to tie additional numbers for 2016. I consumed quite a few of my size 18 imitations, so I began by producing fifteen of these and then added five size 16’s.

Overview

The two keys to tying effective comparaduns are split tails and a deer hair wing that is upright or even angled backward a bit. I was not completely satisfied with my ability to split the tails. My standard practice was to make a small ball of thread at the end of the hook shank, and then I attached the microfibbet tail fibers individually at an angle on top of the hook shank. Next I wrapped backward to splay the fibers against the thread ball. This worked reasonably well most of the time, but occasionally the near fibers rolled up, and the split tail fibers were not on the same plain.

Finished Batch of Cinnamon Comparaduns

I performed a search on split tail fibers and uncovered a tip on a fly tying forum. I adopted this technique for the comparaduns that I tied for 2016, and I am quite pleased with the outcome. When I attach my thread to the hook shank, I wrap back to the end of the hook, and then I hold the tag end of the thread angled upward at a sixty degree angle while I create a ball using figure eight wraps against the taut thread. I do not clip off the tag end of the thread, but instead allow it to dangle from the end of the hook. After I move forward and build the wing, I return to the middle of the abdominal area and attach the desired number of microfibbet fibers to the top of the hook. Once the fibers are adjusted to the proper tail length, I wrap back until I am approximately two or three eye widths from the thread ball. At this point I pull the tag end of the thread forward and evenly split the tail fibers and then angle it down along the side of the hook shank. This causes the near side fibers to splay, and I then lock them by placing some wraps around the tag end thread before I snip it off. I then carefully wrap backward while holding the far side fibers so that they splay against the thread ball and remain in the same plain as the near side microfibbets.

The other trick to creating attractive comparaduns is to leave a gap behind the wing as you wrap the dubbing forward. After you complete the abdomen, allocate a gap and place some tight dubbed thread wraps against the front of the wing while using your left hand to push the wing backward. This causes the wing to angle backward into the gap. After the wing is cocked properly, make some loose dubbing wraps behind the wing to cover any thin spots under the wing.

There you have it. Use my suggestions to create attractive and effective comparaduns of various colors, catch a lot of fish during hatches, and save a bunch of money by not buying expensive dry fly hackle feathers.
