Perdigon Beadhead Nymph - Set of 4 This is a pattern called "Gasolina" from the classic Perdigon nymph used in Euro nymphing. I tied these myself, so there are some variations in appearance, but they have a proven track record. (Tokachi River system, Hoaki River, Hakone Hayakawa... etc.) The fish don't seem to mind the appearance too much.
