    Yes, I'm aware of the problems with collared catskill flies, I haven't use them for many years either, I always tie and use parachutes and comparaduns for that reason. This is a different situation, we are trying to get only part of the fly to sink, not all of it. Even when I've tied them parachute (clickhammer?) style, forward wing, or with CDC the butt of the fly doesn't want to brake the film. This is just the problem I've encountered with very small flies.

    I'd still like to know if there is a difference in the surface tension of different waters, I would think there is, but don't
    know if it would make that much difference for what we're talking about.

    Temperature of the water has probably the biggest impact on surface tension (aside from good surfactants). Surface tension increases as the water gets colder. It could be that the difference in surface tension between your room temperature water at ~20 degrees C and stream water as low as 2-3 degrees C is great enough to alter whether a fly will break the surface or not. You might consider using refrigerated water for your trials.

    I think the type of water is paramount as to if and how the pattern sinks. Most likely, the pattern will sink more easily in moving water than in stillwaters.

    Thanks Gary, that's what I was looking for, makes sense to me.
    GAT, I totally agree they do sink much quicker in moving water and maybe thats been part of the problem because most of my efforts have been for stillwater.

    In between the beer and girls, I managed to learn something in college!

    The image of the BWO emerger tied on an umbrella hook was tied by myself at the Ellensburg fly tying gathering. I have had great success using this design for PMD and midge patterns as well. In my experience, this style of pattern consistently sits below the surface film and presents a trigger to feeding trout. Thanks.

    Thanks for the postback. Not having fished these before, how's your hook-up ratio over normal hooks?

    Mark Mercer,
    My inverted midge doesn't always land in the correct position, but a little twitch of the line usually sets it right. Although my eyesight is about what you'd expect at 72, surprisingly enough the ends of the foam cylinder I use to represent the white gills (and to float the eye of the hook) can usually be seen as two tiny white dots at typical casting distances.

    Okay, now you guys have me interested in uses CDC for midge emerger patterns. I used the CDC for both the shell-back and the gills. Will it float correctly? Beats me but I'm going to try it anyway.

    Well, after testing the pattern in the sink, it does not float with the head up. The CDC can't overcome the weight of the hook. Back to the drawing board.

    well its a good looking fly anyway, I'm sure that the cdc helps it at least sink slower, as far as catching a fish I'm sure it would work. Maybe try white foam shellback with a puff of cdc if you want a surface pattern. just be sure to keep it back from the eye of the hook, foam can get a little bulky, And I cant really tell from the pic, but maybe use a finer wire hook.
