Speed Regime Covers The Spectrum

Swing speed is an increasingly important factor when it comes to determining the ball that suits golfers best, and a recent example of that development is the new Speed Regime from Callaway.
These tour-level balls with urethane covers come in three models, and each is geared toward a specific range of player. The SR 1, for example, is designed for those with swing speeds of 90 mph and slower, while the SR 2 is best for those players who range between 90 and 105 mph. As for those who swing faster than 105 mph, there is the SR 3.
The big differences between these balls are the individual aerodynamic profiles, which are a function of surface geometry, and the makeups of the covers. Consider the SR 3. Callaway engineers say they worked to minimize drag as much as possible during the start of this ball’s flight, when it is experiencing its highest speed, so that it will fly longer. But they believe that minimizing drag in the first stages of ball flight is not as critical for those swing speeds slower than 105 mph.
