Discraft says this about the Ringer (GT): Discraft Stability Rating: X-Line 1.7; Jawbreaker 1.7
It's a beefier Ringer! Your short game will get an instant boost when you deploy Ringer GT. We've taken all the best attributes of Ringer and added a subtle Groove Top that increases grip confidence while shifting the stability of Ringer from 1.5 to Ringer GT's 1.7 rating. Players use it more often for driving and approaching when a soft landing is mandatory and wind needs managing.
