The Twisted Sister is a spin off of the UFO midge and the Bling Midge.
It's roots are on the San Juan River, but this version was designed and tested on the South Platte River in Colorado. It's a simple tie, the magic material is the Madera Wing. If you cannot find Glamour Madera, you can use Spirit River's Midge-Bodi Pearl. It's essentially the same thing.
