Callaway Golf's Big Bertha driver line is on the verge of expanding after a "Big Bertha V Series" model landed on the USGA's List of Conforming Driver Heads.
The equipment manufacturer has yet to release details on the new driver, but according to information listed on the USGA's website, the club has an adjustable hosel and "Speed Optimized Technology" written on the the toe of the club.
Unlike Callaway's Big Bertha and Big Bertha Alpha drivers that were released at the beginning of the PGA TOUR season, the Big Bertha V Series is lacking the adjustable weight system that made Big Bertha and Big Bertha Alpha two of the most discussed drivers on TOUR.
The lack of adjustable weight ports and the addition of the words "Speed Optimized Technology" on the toe leads to the assumption that Callaway is trying to reduce weight and drag, which in turn would improve clubhead speed and ball speed.
Following the release of X Hot and RAZR Fit Xtreme last year, Callaway unveiled a driver with a similar design at the Greenbrier Classic called FT Optiforce. The 290-gram driver came in two head sizes (440cc and 460cc) and featured an aerodynamic profile and lightweight, forged composite crown that reduced drag during the swing by 20 percent, when compared to some of Callaway's other driver models.
It didn't take long for players to take notice of FT Optiforce. The driver quickly became Callaway's most used model late in the season, with everyone from three-time PGA TOUR winner Patrick Reed to 2003 U.S. Open winner Jim Furyk, who used the driver to shoot 59 at the BMW Championship, putting it in play late in the season.
