But I didn’t want to get too excited. I was hitting in nice weather conditions so thought it would be for the best to do a more in depth review back home in the cold winter weather.
Callaway GBB Epic driver review – The technology
There’s no question that with the introduction of a revolutionary new technology Callaway have produced a better performing driver here.
Jailbreak technology promises faster ball speed with increased distance. The two titanium bars behind the club face work together to reduce how much the sole and the crown of the club deflect through impact.
The clubhead features Callaway’s latest titanium Exo-Cage meaning that almost half of the head’s surface (46%) contains triaxal carbon with the crown weighing less than 10g and the sole just 5.8%.
These weight savings means that this is the lightest crown ever designed in a Callaway driver.
Epic’s increased shot- shape control comes from the sliding track weight system. In the new model the track is shorter compared to previous models and has a heavier sliding weight.
This heavier weight helps increase MOI in the driver as well as offering 21 yards of shot-shaping which is a 22% increase from the Great Big Bertha.
Callaway GBB Epic driver review – The results/NCG verdict
At the start of my fitting session out on the range at TPC Las Vegas we noticed a bit of a fade which is very common for me.
After a few tweaks, noticeably moving the sliding weight all the way across into the maximum draw setting, my shot shape was completely different and if anything, producing more of a draw shot.
Out in Vegas I hit four shots on Trackman with an average carry of about 260 with a total of 280.
Bu in order to make it a fair and honest review I wanted to look more closely at the numbers I got back in the cold weather in England.
I was very pleased with the results, despite not hitting it great on the day I still managed to average over 270 yards in total distance.
What was also very pleasing was my spin rate was down.
I am known for having a very high spin rate with the driver so to see some shots result in less than 1800rpm is definite cause for optimism.

To have a driver that gives me a lower launch, with a lower spin rate and a longer carry and total distance is just what I’ve been looking for.
The Callaway GBB Epic driver gives me all of this things.
As a 13 handicapper my obvious target is to get down to single figures, and with this driver in the bag I feel a lot more confident than I did without it.
Despite a quite expensive price I can’t give any faults with the performance or the look of this driver. It has a very premium feel and is giving me about 20 yards extra distance.
