The Rhody flatwing is my go-to
You can adjust the color anyway you like as long as you remember to keep it very sparse.
I skip the peacock topping myself as it tends to foul and instead substitute some dark bucktail. Purple or Navy blue
Rhody Flat Wing
(I just read the recipe.... before tying in the tail hackle (step 3) you need a "pillow" to keep the tail from fouling
This is nothing more than a dubbing bump tied in on top of the bucktail wraps at the end of step 2.
I use the fluff off of the saddle hackle, but you can use anything that's sitting around)
