UV2 Roe Skein Yarn is a new material for us and is pretty amazing. First we make all of Roe-Gain egg patterns with it. The year is used to as a shuck that encases the bright egg yarn. The neat thing is it become almost translucent once wet. It is deceiving when you tie a fly with it. It really need to be submerged to see why we use it. I recently did a tying article in Fish ALaska magazine and showed how to tie a UV2 Roe-gain. These flies are soft and fish a lot better than the traditional egg pattern.
