In 2007 Mizuno introduced a sliding weight system called Fast Track – to alter a driver’s draw/fade tendency. Mizuno has now evolved this breakthrough technology to also be able to customize spin rate and launch angle in the JPX-850 – helping all swing speeds achieve maximum possible total yardage. A massive playing profile with a low and deep extended weighting system launches the ball into an optimized, low spinning orbit – from whichever QuickSwitch setting you choose.
