The RS2 is a fly with a lot of information and story to back it up. You can read all about it and the inventor Rim Chung at the official site for the fly; http://www.rs2fly.com/. The video was produced by Juan Ramirez whom we have featured on here before and will no doubt feature again. He has some serious skills behind the vise and can back it up on the water. Enjoy and check out the RS2 site for a list of variations.
