Callaway Great Big Bertha Epic Driver
Long name, long drives. The Callaway Great Big Bertha Epic Driver is the company's newest flagship, using clever technology to improve performance. During impact, a typical wood's crown bulges upwards while the sole moves downwards. The Epic and its Tour-ready Epic Sub Zero counterpart use a pair of parallel bars — dubbed Jailbreak Technology — to keep these pieces from flexing, instead transferring that energy to the face for faster ball speeds, added distance, and lower scores.
