Mizuno introduced a sliding weight system called Fast Track to alter a driver’s draw/fade tendency. Mizuno has now evolved this break through technology to also be able to customize spin rate and launch angle in the JPX-900 Driver, JPX-850 Driver, Fairway, Hybrid helping all swing speeds achieve maximum possible total yardage.
“The genius of the new Fast Track is that it adds the dimension of launch angle and spin rate. Now the player is truly in control of maximizing all aspects of their ball flight off the tee.”
