Like Staff Model, Staff Model R is a Tour-caliber, 4-piece urethane golf ball that also delivers unmatched precision, speed and consistency. It’s also the first golf ball to feature an unpainted urethane cover that delivers a lower flight trajectory, and ”grabs” the wedge surface for enhanced greenside spin. For Staff Model, Wilson implemented a finely controlled paint application process. The result is a more uniform coat of paint that translates to more consistent performance and supreme shot-making confidence. This is the ball for players who demand the utmost in confidence and consistency. This is performance perfected.
