Like many golfers today, I was eager to see the new generation of Big Bertha and specifically the Callaway Big Bertha Alpha driver.
The idea Callaway had was to use the Big Bertha name to signal what they consider a major leap in innovation and Alpha is certainly worthy of the name. Callaway offered a couple of examples of the types of players and swings that suit core-up or core-down. They said someone like Phil Mickelson, who has a "steep" attack, tends to produce a lot of spin and thus uses the core down, to lower the spin rate.
Callaway say that it is a pretty even split on Tour between core-up and core-down, with around 60% of players choosing to insert it with the heavier end down. The look of modern drivers, especially at address, has advanced and varied vastly in recent seasons. Whilst the 'Captain America'-like sole design may be busy and full of technology and features, the Alpha's look at address was clean and simple with a traditional, slight pear-shape.
Alternatively, someone like Branden Grace who has a shallower swing and doesn't produce too much spin, needs to have the Gravity Core facing up to help add some spin and launch to his driver. The ball went further and didn't 'climb' as much as before. Whilst I was carrying the Alpha the same distance as my current TaylorMade SLDR White driver, around 250 yards, I was able to lower my landing angle from 35 to 30 degrees, meaning the Alpha will run more and perform better in the wind.
I would recommend this driver to better players especially and those who like to tinker and perhaps don't require the added forgiveness of the standard Callaway Big Bertha driver.
