Speedline aerodynamic shaping is designed for less drag, faster clubhead speed and longer yards which equals more distance.
Speedline is a high performance 460cc driver with low aerodynamic drag, achieved through improved crown shaping, an optimized face area and heel/toe scoops.
Less drag from Speddline driver, equals 2.5 - 4.2 mph higher clubhead speed, equals 3 - 9 yards more distance.
Aerodynamic shaped crown equals less drag.
Redisinged areodynamic heel and toe equals less drag.
Optimized face area with improved transition from face to body equals less drag.
