Callaway unveiled their new line of golf balls for 2014. The balls, which Callaway calls "Speed Regime," come in three versions: the SR 1, SR 2 and SR 3.

The Speed Regime balls are designed to match golfers' swing speeds. The SR 1 is for players with swing speeds 90 mph and below.

The SR 2 is made for swing speeds from 90-105 mph, and the SR 3 is for better players with swing speeds in excess of 105 mph.

For the SR 1, Callaway designed a ball that helps players increase lift towards the end of their shots despite slow swing speeds. The SR 3 has a profile design that reduces drag at higher speeds. Golf balls fly fastest immediately after impact, which is the same time that drag forces are strongest on the ball, causing the ball to slow down. In theory, by reducing drag the balls should fly farther.

Finally, the SR 2 is balances the technologies for reducing drag and increasing lift found in the other Speed Regime models.
