Anyone see OL Adcock and Ed Ashby's newest thing. They are looking to reduce the surface area of fletchings (2 1/2"), make noise pretty much non-existant, and stabilize a fixed blade broadhead. The fletch is put on straight with a helical clamp. FOC is exteme. That red ring is not paint, it is called a turbulator. I guess it's from an aviation concept. Interesting.
