Tying perfectly lifelike imitations of nymphs with vinyls, plastis, and SpaceAge dubbing materials is often at cross purposes. It’s the nymphal movement that stimulates the the trout’s feeding response, and most super-realistic nymphs I’ve seen lack this movement. I’d file most of these imitations under Arts and crafts. It’s how the nymph looks to the trout, not the angler, that counts.
