First Look: Callaway Big Bertha drivers
The newest Big Bertha is designed to max out distance for average players. It has a 19% larger sweetspot (the face area that provides ball speeds within 2 mph of max speed) than last year’s RAZR Fit Xtreme, and features the same 8-way adjustable hosel (four lofts, two lies) as in Callaway’s Optiforce drivers. The coolest update is an 8-gram weight that slides on a five-inch track along the back edge of the club. Moving the slider can shift the club’s lateral center of gravity up to 0.138 inches. Callaway says it translates to a 360 rpm change in sidespin, and a 15.6-yard dispersion.
In addition, a composite crown helps to keep the club light despite the rear track, while added perimeter weighting boosts forgiveness. Available in 9°, 10.5°, and 13.5° lofts with a 45.5-inch Mitsubishi Rayon Fubuki shaft. The club will be at retail on February 14, 2014. $399.
Its sister product, the Big Bertha Alpha, has adjustable loft settings to strengthen loft by 1° or weaken loft by 2°. The Alpha, for better players, has a first-of-its-kind removable carbon tube in the head -- heavy tungsten on one end and a light nylon on the other -- which allows you to alter backspin up to 300 rpm without changing loft. Positioning tungsten near the sole creates a mid-spin head; tungsten higher in the head makes it a low-spin driver. The club will be at retail on February 14, 2014. $499.
