Here is a short video on tying the Mercury RS2. This is the PMD version, but you can change colors easily to match any insect you want to . I only tie these in PMD and Adams Gray color. Maybe black as a third color. Do me a favor and tie your tails a bit shorter than I did. I didn't notice that they were a bit long until I looked at the fished fly in my hands. I was in a hurry to get this done. See what happens when you rush things?

A quick and easy tie, this is a true guide fly. Easy to change colors and to get a different look, this thing is effective in PMD, gray and black to name a few. I would keep the tails a bit shorter than what I did here.
