I'd watch Mike Radencich's video again. The technique of a bend just behind the horn's tie in point springs the horns toward the centerline of the fly., and minimal wraps should be necessary to hold it in place. Your head formation needs to avoid disturbing the horns, and if they are only held with a few wraps you might have trouble. One way to avoid this is to form your head, then tie on the horns (with only a couple of wraps, with thread untwisted), then varnish the head. One other thing, make sure that you are using the correct barb length for a given size fly. If you trim the base of a barb of macaw because it is too long, you are trimming out the stoutest portion of the barb. Note also that the longer the horn fiber, the more likely it is to droop, and Scarlet Macaw seems almost as limp as a wet noodle. That is why you see so many patterns with crossed horns somewhere about 3/4 down the wing to add structure to a very weak element. Drooping horns are no fun at all, especially if you have framed the fly... Cheers, dave white aka "Swill Gordon"
