Weighing In: GBB Epic Driver vs. GBB Epic Sub Zero Driver
Callaway has two of the hottest drivers on the market this year, the GBB Epic driver and GBB Epic Sub Zero driver. While the two models have much of the same technology, there is a distinct difference to consider when choosing one.
GBB Epic Driver Technology
The GBB Epic and GBB Epic Sub Zero drivers share two exciting new technologies. First is Callaway’s new Jailbreak technology, which consists of two titanium bars running from crown to sole. Located directly behind the club face, these bars stabilize the face flex upon impact. The thinner, more stable face, provides more consistent energy transfer from a greater portion of the face. The energy transfer produces higher ball speeds, more forgiveness, and a better sound.
Multi-material Crown Construction
Callaway’s head construction, the second new technology, makes the Jailbreak technology possible. A titanium exo-cage combines with a crown and sole made of triaxial carbon. 46% of the club head made of this carbon, saving enough weight to place the titanium bars behind the face. Using the lightweight carbon let engineers ideally place the CG to increase the MOI and forgiveness.
Difference – Weights
The difference between the new Callaway drivers is the weighting systems. The GBB Epic driver features a sliding weight on the back of the clubhead. It allows for up to 21 yards of ball flight direction correction, ideal for the player looking to customize ball flight from side to side.
The GBB Epic Sub Zero driver, 2 weight ports take the place of the sliding weight. One port is located in the front of the sole and one toward the back. Adjusting the 2-gram and 12-gram weights vary launch and spin for trajectory and spin control. Putting the heavy weight in the back increases launch and forgiveness. Switching the heavier weight to the front allows for more penetrating ball flight and less spin. The GBB Epic Sub Zero maintains the level of forgiveness of its counterpart, with options to launch higher or lower.
Weighing Your Options
Depending on what you desire out of a driver, either the GBB Epic or the GBB Epic Sub Zero could be the right choice for you. For help with left or right ball flight, choose the GBB Epic. For the player preferring to adjust their flight up or down, the GBB Epic Sub Zero is for you.
