If you're not playing a Tour ball that's been engineered and fit to your swing speed, you are giving up significant performance. The Callaway SR2 Golf Balls offers optimized aerodynamic performance for more distance for athletic swing speeds. A very soft urethane cover delivers Tour-level control and an incredibly soft feel. Superior spin separation regulates spin and control, increases ball speed, and maximizes distance.
The SR2 has the best aerodynamic performance for players with swing speeds between 90mph and 105mph. The HEX pattern is engineered specifically to optimize lift and drag with a long, stable, penetrating ball flight that holds its line in the wind.
This very soft urethane cover delivers Tour-level control on shots into and around the green and with an incredibly soft feel.
A soft inner core with low spin off the driver provides for long distance. A firmer outer core with higher spin rates offers more spin, control, and aggressive stopping power on short irons and wedges. Thin inner and outer mantles increase ball speed and reduce driver spin to maximize distance. That's the Tour performance used in SR spin separation.
Did you know refinished golf balls have been formally accepted by the USGA. Rule 5-1/4 of the USGA rule book states that it is permissible for such a ball to be used. So there you have it, Refinished golf balls are permissible in tournament play!.
