The Challenger OS is a more overstable version of its older brother the Challenger. It is flatter than the Challenger and works great as a driving putter. It is also ideal for hyzer putts, forehand approach shots and throwing into a headwind. This special run of the  Challenger OS is Chris Dickerson's preferred throwing putter and includes a Limited Edition stamp with his logo and comes in Discraft's Z plastic. 
The Z Challenger OS works great as a driving putter, allowing you to launch it off the tee with confidence.

D Challenger OS. This putter has the classic Challger feel with a bit more stability. This is a spin putters dream. Reliably overstable to not be affected by the wind easily. These putters have saved me strokes on the green.

Jared Pittman, Team Discraft
Challenger OS is one of the best throwing putters I have ever used. It goes straight with a stable finish everytime no matter how hard I throw it. A truly awesome disc.
