RS2 Emerger Fly tying tutorial:

Tiny emergers can be the best way to trick fish on a feeding streak, especially when you are unsure about what they are feeding on. RS2’s can be tied in a variety of colors, but dun, pale yellow, and black are ideal. Fish these deep or mid column during autumn reservoir fishing days, or just in the film on a slow moving stretch of stream. Either way, trout will not be able to resist. #larvalace #fliesthatcatchfish #KISS #flyfishing #RS2 #emerger #puresilk
