Callaway SR2 Golf Ball Prototype

This is the unreleased Callaway SR2 Golf Ball scheduled for 2014!  SR stands for Speed Regimen and these golf balls will come in Callaway SR1 for swing speeds lower than 90mph, the Callaway SR2 (pictured) for swing speeds of between 90 and 105mph and the SR3 for swing speeds greater than 105mph.  We’ll be taking these golf balls for a test drive soon so stay tuned to see the first review of the Callaway SR2 Golf Balls.
