The new Big Bertha Alpha's Gravity Core lets golfers adjust spin independently of launch angle, a natural (and dramatic) extension to loft adjustability in a driver head. This adjustability breaks the fixed relationship between launch angle and backspin for the first time, providing a major asset in the fitting process to find optimal distance for a wide range of players' abilities.
The Gravity Core sits within the club head in a carbon tube that connects the crown and sole. It has a tungsten end, weighing 10.5g, and a glass fibre reinforced body, weighing just 1.5g. The gravity core can be inserted into the club head two different ways, which allows golfers to change the vertical centre of gravity and alter the spin rates based on how it is positioned. When the tungsten end is closest to the sole, it will create a lower centre of gravity and lower backspin. When the tungsten end is inserted first and therefore closer to the crown, it creates more of a mid-CG position.
Generally, players with above average head speeds or those who are trying to prevent excessive spin will benefit from the lower centre of gravity, which a creates a flatter, more penetrating trajectory accompanied by more roll out. For those looking for a more controlled and workable ball flight and less roll out, the mid CG position is recommended. Player testing has shown as much as a 600rpm spin differential between the two Gravity Core settings without a change in loft.
* The Gravity Core lets you adjust unwanted spin independently of launch angle, so you get completely optimized ball flights and longer distance.
* Together with the adjustable hosel, get even more ball speed and distance.
* Dial in your preferred directional bias with the adjustable weights, enhancing a Draw or Neutral shot shape for more accuracy.
* Premium Mitsubishi Fubuki Zeta Tour shaft
