Yes C-Groove Tiffany Centre Shafted Putter. Since their introduction in 2001, over 100 tour players throughout the world are now using Yes! Golf C-Groove putters. On any putt, on any green, a putter's impact on the golf ball often results in skidding, sliding, back spinning, and even hopping before the ball can begin rolling on the green. Even when struck on the right line, these effects are the principal causes of missed putts. Therefore, the key to more accurate putting is to achieve forward rolling motion immediately upon striking the ball. The Yes! Golf C-Groove putter does just that, far better than any other putter in the game. Upon impact with the golf ball, the patented concentric edges on the C-Groove putter face grip the surface of the ball and apply physical forces which simultaneously lift the ball out of its resting position and impart an over-the-top rolling action. Using the Yes! C-Groove putter creates stabilization in the rolling motion dramatically sooner than any other putter. Forward rolling motion is as much as 6 times greater with the use of the Yes! C-Groove putter versus other putters. Over a 20 foot putt, the C-Groove putter was tested by an independent testing company against several putter models of the major golf companies. In all cases, the C-Groove putter dramatically outperformed the competition. Whether struck dead centre, a millimetre or even a quarter inch off centre, the Yes! C-Groove putter rolls the ball sooner, for more consistent length and more consistent direction. That translates to more putts made, no matter the circumstance, no matter the pressure.
