The Discraft Elite X Soft Challenger is an amazing overstable disc golf putter, stability of 1.0 (moderately overstable) and very popular with advanced players. It's a softer version of the Challenger. Whether you're putting or throwing hard, The Soft Challenger won't flip over in moderate winds. Players love the extra grip they get from Soft Challenger for a consistent release putt after putt. It can get around trouble for those long hyzer putts and is overstable enough to take a good amount of snap on approaches. Great for wind and distance putts.
