Callaway GBB Epic/Sub Zero
Our Review:Both versions (standard and Sub Zero) feature the company's signature face that wraps around the crown and sole. The edges of the face function like hinges to expand the flexing to a wider area. Weight is saved through the use of a carbon crown to lower the center of gravity, compared to last year's Great Big Bertha. That makes these adjustable heads more stable and easier to launch off the ground with less spin.
Specs: 13.5, 15, 18, 20, 21, 24
