What's up, guys! :)
I absolutely love this driver! I'm gaining at least 10 yards further off the tee. Even in heels ;)
As it's big claim to fame states, you won't leave any yard behind with the Great Big Bertha. With the Next Gen R•MOTO Technology and 19 different shaft options and head weight configurations, you'll be sure to find the best fit to gain more yardage with the GBB.
The best thing about the 19 different shaft options is that they come with no up charge. Saweet!
Here's a cool study Callaway did with the GBB explaining why they created the technology they did in the development of the driver.
I'll also leave a list of the different shaft options and specs for you guys which you can also find on Callaway's website:
