The Myth disc from Infinite Discs was PDGA Approved on 3-29-2018.
"The Myth is the first putter in the Infinite Discs brand lineup and we wanted to start strong. The Myth is a dependable, beaded putter with a comfortable rim that can be used for precision putting, or as a driving putter and approach disc. If your putting game can't be a thing of legend, then at least let it be a thing of Myth. Inspire friends and family to talk about your epic putts around late-night campfires for generations to come." - by Infinite Discs
