Tied small - 18, 20, & 22 - it can imitate baetis species and midges. Yet, very visible!! in spite of your casting distance and light (weather) conditions!
Originally I started tying these just to add more colors in my boxes (really!). However, right off the bat, they were easily consumed by trout! Yet, these are easy for me to wrap up some quickly for next trips. These two immediately became my favorite, go-to, and most reliable attractor & searching patterns.
I admit the very first catch was this pretty Whitie on a small cripple during midge hatch.......
Here's a real proof! A nice hefty Yellowstone rainbow came up on #14 Cripple!!
