The Orange Ruthless has long been one of my favorite striper flies. It’s a simple pattern, and a good place to start if you’re just getting into flatwings. I like this fly about 2 1/2″ long, but I’ll tie it even smaller if the bait size warrants. The Orange Ruthless gets a lot of swim time as part of a three-fly team; I tend to place it in the point position. Although it’s a clam or cinder worm, it does double duty as a grass shrimp (or at the very least something that looks alive and good to eat.)
The SC15 hook does not sharpen well, but it is sticky sharp out of the pack and holds its point for a long time. I chose it because it’s easy to find and very light. You can get away with strung hackle for both the tail and the body, but make sure the feathers have plenty of web.
If you have Ken Abrames’ A Perfect Fish, you’ll find a fly called the “R.L.S. Ruthless” in the chapter on single-feather flatwings. This is a variant of that pattern, taught to me by Ken himself at a Tuesday night tying session many years ago. It was the first striper fly I ever tied, and I had the good fortune to be seated next to the artist, lashing bucktail, flash, and feather to hook under his watchful eye.
