Bettinardi Super Stroke Flatso 1.0 Shaping the Future of Performance The SuperStroke CounterCore? Flatso? putter grips feature a revolutionary pentagonal profile to allow for increased consistency due to its wider flat-front and multiple edges with the added adjustability of CounterCore? Technology. Flatso?s also feature No Taper Technology as well as CROSS-TRACTION surface texture to help you with a smooth, consistent, and reliable putting stroke. Putter grip includes 50g CounterCore? weight and wrench. For those who prefer not to utilize the 50g weight, an aluminum cap is also included. CounterCore: Advanced CounterCore weighting reduces face angle rotation and improves path for a more consistent stroke. Adjustable Weight System: An adjustable weight system engages larger muscles for a more stable and repeatable stroke. No Taper Technology: Our patented technology helps golfers minimize grip pressure with a unique parallel design. The uniform lower hand profile assists golfers in quieting their hands and adding consistency to their stroke. Cross-Traction: The Cross-Traction surface texture creates a more consistent non-slip grip. Fitting Tape Included
