Ready to get the most of your putter grip by using back-weighting technology? The Countercore allows you to fine tune the feel and stability of the putter by adjusting the weight of the grip. Every new Flatso with CounterCore putter grip comes with a 50g back-weight that engages larger muscles in the arms, shoulders and back, which results in more of a pendulum motion. The Super Stroke Flatso design utilizes a pentagonal profile along with a wider flat-front and multiple edges. With the back-weight in place, you'll instantly change the feel and response of your putter. Allowing you to gain more stability and remarkable control.
