Roach

Discraft says this about the Roach:

Discraft Stability Rating: D-Line 0.0, Big Z Line 0.0
This disc has been thoroughly field tested as the 2015 Ace Race prototype disc, which was made available in Pro D plastic. This is the first time players can get one in Z plastic. A straight flier with extra glide, the Roach is crafty in avoiding danger while incessantly pursuing chains. Just point and shoot. It feels great in the hand too. We expect the Roach to be multiplying quickly on courses everywhere.
