D esigned to control slices and temper draws, the sliding weight on the pe- rimeter of Callaway’s new Great Big Bertha driver is hardly an extraneous feature aimed at only the most demanding golfers. “Controlling the lateral shot shape is the most important factor for improving performance,” says
Evan Gibbs, Callaway’s manager of woods R&D. The Great Big Bertha, an update of 2014’s Big
Bertha, saves weight with a lighter ribbed face and a composite crown. This allows the sliding
weight to be 25 percent heavier (at 10 grams) to help reduce sidespin. The Great Big Bertha has
an eight-way adjustable hosel, and with Callaway’s 19 no-upcharge shafts, it can play between
295 to 325 grams ( 9, 10. 5, 13 degrees; $450, in stores Aug. 28). —Mike Stachura
