The Whale disc by Innova Discs was PDGA Approved as of 12-7-2014.

"Available in XT plastic, the Whale is a beefy, Aviar-like Putter that has the stability of Innova's Big-Bead Aviar Driver with nearly the same low-speed over stability as Innova's Putt and Approach. It flies like a driver and lands like a putter. The Whale is easier to throw side-arm because of its superior torque resistance. Available weights: 150 to 175 grams." - by Innova Discs
