The Sting (2017 Ace Race) disc by Discraft was PDGA Approved on 11-7-2017.
"The global Ace Race evaluates a new Discraft prototype each year with the help of 20,000 testers, and last year the players were once again pleased with the results. The design goal was to create a disc that is easy to control, holds an almost perfect line on all throws, and fits comfortably in most hands. The Sting achieved all of this.
Here's what the disc can do:
- Holds an almost perfect line on big throws
- Even new players can hold an anhyzer line with long glide
- Rip it for high-speed hyzer flip drives
- Delivers long flights to reach maximum distance
Stability rating: 0.0 | Available weight range: 160-174 | Suitable for all players" - by Discraft
