Our test team casts its eye over the brand's latest model in its Mizuno JPX850 driver review
The Fast Track weight system first seen in 2007 makes a return in the Mizuno JPX850 driver. It features two twin eight-gram weights that can be located on either a central sliding rail, or on slots in the heel and toe.
This allows for 10 settings, which can vary lateral trajectory and, for the first time, spin rates and launch angles. The face and crown are engineered to increase ball speeds.
Will suit… players after a great-looking head with plenty of adjustability on offer.
The JPX850 is also one of our top 10 best drivers for 2015
