The large head is counterbalanced by a 15-inch, 125-gram grip, which increases “stroke stability,” which is your ability to swing the head on a smooth and accurate path. Counterbalancing amplifies stability by up to 60% compared a traditionally weighted putter. The putterhead itself is also extremely stable, with an MOI measurement of 6,000+ to help it resist twisting on mis-hits toward the toe and heel. That protects you from losing ball speed, helping you get the ball to your target instead of running out of speed and coming up short. Spider Si Slant also delivers outstanding feel and roll, owing to its PureRoll Surlyn face insert that’s designed to promote smooth and consistent roll as the ball leaves the face. And the face is easy to aim with accuracy, thanks to the simple, elegant head design and contrasting crown colors. Spider Si Slant has already been put in play on Tour, as more and more players make the switch to a counterbalanced putter.
