'Many of these findings influenced our thinking with FT Optiforce but also powered some key choices in the X Hot Driver, namely making it a lighter overall Driver product, compared to our previous designs.' Hocknell said. Hocknell and his team conducted an extensive study into driver length and driver weight. Due to launch to the market July 12th, the new driver is lighter than many recent Callaway drivers. 'However, we were so excited about вЂFalconвЂ™ that we decided to return to the prototype and see how we could push the concept even further by adding our newly developed вЂadjustableвЂ™ technology.' 'We then held onto this research for a period of time while we concentrated our R&D efforts on satisfying the consumer demand for вЂadjustable weightingвЂ™ products and introduced RAZR Fit Xtreme and X Hot Drivers.' We realised we could produce a traditional head shape, that doesnвЂ™t have any unusual visual features to it, but had a definite advantage in adding head speed at the point of impact, based on the same effort applied by a golfer. 'We had developed a prototype head that we had called вЂFalconвЂ™ which had the best aerodynamics of any Callaway Driver we had ever made above the 400cc volume range. We heard from Callaway's own Doc Hoc, Alan Hocknell, Senior VP of R&D, to hear learn more about the new driver, the design and what inspired it. You may have already seen the lightweight FT Optiforce driver in the bags of Callaway's Trevor Immelman, Tommy Gainey and Andres Gonzales. Known as the 'Falcon' or 'Project Black Tail' within the Callaway R&D department, the new driver offers adjustability, improved ball speeds and light shaft options. Lighter and more forgiving than the recent Callaway X Hot driver, the Optiforce driver also features a higher launch. Three days after they released the Mack Daddy 2 wedge, our friends at Callaway Golf have announced their new FT Optiforce driver.
