Discraft Z Mantis: it preys on chains!
The Mantis (Ace Race disc) from Discraft was PDGA Approved on 12-1-2013.
"The Mantis (formerly the 2013 Ace Race prototype) is a utility driver for experienced players, and a distance driver for newer players. A touch of overstability enables control at slow or high speeds. Rip it hard for a hyzer flip or "S" distance shot, or hold a straight line at slower speeds. Try Mantis for straight thumber shots too! Arriving at disc golf retailers now." - by Discraft
