The slim 3.0 is the most played 060203 on the Tour. The new slim 3.0 with counter core technology lets the golfer fine tune the feel and stability of the putter by adjusting the weight of the grip. Every new counter core 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. Our patented no taper design promotes even grip pressure, which leads to better putting. It can also be played without the weight if you prefer.
