Challenger OS

The Challenger OS is the most overstable of the Challenger putters, rated 2/3/0/3 with a beaded rim: no turn, low glide, and a fade 3 ending on a putter frame. It is the family's wind and utility disc, for approaches that must finish left and short drives that need to die on command.

Overpowering it is nearly impossible, which is its job description: flick upshots, headwind lay-ups, and spike-hyzer approaches all end the same way. The bead keeps the release consistent.

Discraft certified it in September 2017 (PDGA cert 17-107), a month after the understable Challenger SS, giving the 2003 classic Challenger siblings in both stability directions.

Putter Line and Pro-D are the base feels, Jawbreaker, CT Jawbreaker, and Crazy Tuff cover the firm blends, Rubber Blend leans soft, and Big Z plus Signature Z Line runs carry the premium and collector stamps.
