The "hands down" most effective all around fly pattern for Silvers in the Puget Sound area is the Clouser Minnow. Everyone has their own special color combination whether it be green & white, chartreuse & white, pink & white or olive & white. Most tie a size #4 to #8. My "go to " Clouser is a green "baitfish" angel hair over pearl angel hair tied somewhat sparsely in a #4. Second to that is a green poly-bear over white northern bucktail, also on a #4 hook. Do you need tying instructions for the Clouser pattern?
