The Crank made by Discraft was PDGA Approved on 7-8-2013.
"After more than a year of intense development and testing, the DC engineers have nailed the sweet spot with the Crank driver. Discraft recruited dozens of average players who wanted more distance, studied their form and power, and built a disc that works for distance driving every time. Crank combines intense glide with amazingly forgiving control that won't easily turn over or finish with a bite. Think of a well-seasoned Nuke, or better yet, Crank one out for yourself!" -by Discraft
