ClubTest 2014: Callaway Big Bertha Alpha Driver
Callaway Big Bertha Alpha Driver
Category: Tour Drivers
WE TESTED: 9° with Mitsubishi Fubuki Z graphite shaft
KEY TECHNOLOGIES: “Gravity Core” rod in the head allows you to manipulate weight to optimize launch and spin. An 8 percent larger face with variable thicknesses helps to boost ball speed. Loads of adjustability for loft (+2°/-1°), lie (neutral/upright), weighting (heel/toe) and CG. Heavier head requires a higher-balance-point shaft.
DISTANCE: It’s long, period—one of the top-rated models; the Alpha seems to afford limitless distance when properly adjusted.
ACCURACY/FORGIVENESS: Tons of room on the face to miss it a bit without losing much distance; testers have to make a really bad swing to produce a lot of sidespin; shots hold their line—very forgiving and straight.
FEEL: Powerful “pop” off the clubface; you can feel the ball compress but it’s not too rigid; head is very stable through the impact zone.
PLAYABILITY: Very repeatable mid-trajectory flight that’s fairly easy to turn over; after adjustments it does what you want with a ton of consistency; testers are impressed at how the carbon “Gravity Core” rod is used to alter flight and spin.
LOOK: Our testers really like the shape, dark blue paint job and square set up; the contrast between a dark crown and metallic face make it easy to aim properly.
A few testers say the amount of adjustability might be overkill; trajectory is a bit lower than some guys prefer.
BOTTOM LINE: One of the highest-rated models. Ranks near the top in all categories.
HOT STIX'S TAKE: Launch - Low; Spin - Low
