The Berserker disc by Viking Discs was PDGA Approved on 1-17-2017.
“Long anhyzers and rollers are easy to handle with this fast control driver. Beginners can use Berserker for s-curve distance shots. This understable disc will pop up from hyzers to flat, and glide a long way to maximum distance. Don’t fear Berserker, it will help you improve both technique and distance!
