Surveyors' tape starts to loose its usefulness as wind speeds increase. You may need to try something heavier. My Hood flags came equipped with relatively heavy, red cloth ribbons, which were eventually replaced wit surveyors' tape, because of the lightness of the conditions that I usually shoot in. In windier conditions, Skip Otto had two tails on each flag. The heavier one hung from the bottom of the vane forward of the back corner, and was made from the heaviest black, crochet or knitting yarn that he could find, perhaps a half a dozen strands that were all knotted together every six inches or so. The lighter ribbon was attached behind it to the back lower corner of the vane. Because the heavier one was in front, they did not tangle, as the lighter one maxed out, the heavier one would have picked up. It has been a long time, so if I have any of the details wrong, someone jump in and correct me. I am not a fan of daisy wheels, but I still see them in pictures of matches that are held back east, some someone must be. IMO they reduce responsiveness to wind angle change during light conditions. Perhaps the reason for the regional difference in their use is because of the differences in typical conditions. I have a half dozen for my Hoods sitting on the shelf, fitted with brass tubing bushings to improve their fit, with one blade painted black. The other problem that they have is that if they are too well balanced and have little friction, they do not stop rotating when the wind does, and when the wind is doing fast changes may confuse things because of this. The best way that I know to compare flags, or components, is to put them both out, so that neither is in the other's wind shadow and watch them to see which one looks like it is picking up first with a change, and how much information is available about speed and direction. One more thing, for tails that may want to spin, ball bearing snap swivels, that you can usually find at a fishing tackle store, make an easy to use method of attachment to vanes. They are not needed for surveyors tape, but are handy for heavier tails that may want to spin, and in doing so bind up at their point of attachment.
