The Challenger OS is a more overstable, flat-topped version of the popular Challenger. This putter works best for driving, throwing into headwinds, weaving forehand approaches, and tossing hyzer putts. It is overstable enough to meet a majority of a player’s needs without becoming a meat hook.

The flight pattern is | 3| 5| 0| 2.5|.*
