WB’s are tied and fished, whether intentionally or just kicking along, to be imitative of a leech and only indirectly a dragon nymph or damsel nymph or baitfish. If, as I wrote earlier, trout eat less leeches than we assume, then perhaps WB’s should be tied more often to simulate stout dragons or long dragons or slender damsels. Also, much can be done to imitate bait fish in appearance and presentation.
