The R.A.G. (Red and Gray)d Gray) I really like flies with light blue dun wings for the rivers with smelt populatioins and flies with red colors always work well so this pattern was conceived while playing around with those 2 colors. Its a great brook trout fly and also a good injured smelt pattern for spring time trolling. Mustad 94720 Hook  $5.25 Select Sizes Size 2Size 4Size 6 Martinek Hook Display Fly  $25.00
