I tie both ways, fancier for flys I give away and simpler for myself. For example I tie my Hare's ears with no wing case or legs. Haven't noticed in any difference in appeal to the fish. I admire beautiful products of the fly tyers art and try to tie them myself. Do the fish care? I think not. I think impressionistic beats realistic in fly fishing . Some think that impressionistic flys look more alive than realistic. Maybe they're rigkt.
