Flood Tide Fly
I tied this up the other night on a whim and had great success with it the following day on reds in the grass. I'm not sure if it is someone's fly or idea, but it's simple and looks great in the water. I was going for something crabby with the splayed feathers, tarantula brush and then the hackle and the front. It's tied on a Gamakatsu B10S stinger in #4 (maybe #6, can't remember).
