The Witness disc from Dynamic Discs was PDGA Approved as of 2-17-2014.
"The Witness is a great fairway driver for players with lower arm speed. An understable flight path and tremendous glide make the Witness an excellent choice for players looking to gain distance without sacrificing accuracy. Bigger arms can use the Witness for controlled anhyzers, hyzerflips, and rollers." - by Dynamic Discs
