Jerry Criss and I go back a long time (at least as my fly fishing adventures are concerned). We were both members of the Central Oregon Flyfishers and were just a very small minority who enjoyed the pleasures of soft hackled flies and spiders. Jerry is a wonderful and studious tier and fisherman who spends countless hours on the water "testing" patterns. I like to fish tried and true patterns, tweak them a bit, change colors etc and hit the water confident that I'll catch fish and not too concerned with catching the most fish. Jerry is one of those types that will go after the same fish in multiple days with different variations of a pattern until he catches the fish. Most of his patterns spend a lot of time wet in the Fall River of Central Oregon. Not an easy river. Gin clear, quite a bit of pressure, and smart fish. I can usually be assured that if he says it is a good pattern, so it is.
Anyway, I took a photo of the fly in question here that he was tying. Notice that the dry hackle is very short, purposefully. It only serves a functional purpose, to give your pattern a longer float, but allows the partridge hackles to lay upon the water and retain it's attractive movement. It is not long like many of the Jingler patterns. He also uses Coq de Leon fibers for a tail to aid in a longer float time.
