The Mizuno JPX 900 driver is the most adjustable driver for launch parameters on the market. The Infinite Fast Track in the center of the sole raises and lowers the ball flight and spin with 2 8-gram weights. Those weights can also be put in the outside tracks to promote more draw and fade bias.
Also on the sole of the Mizuno JPX 900 driver is the Visual Face Angle Adjuster, or VFA. This is an adjustable weight plate that changes the look of the face at address. Doing this gives the user confidence as they set up to the ball.
A new CORTECH Face on the Mizuno JPX 900 driver boosts ball speed by 5 mph over the JPX 850 on hits in the sweet spot. It also thins out the areas on the outside of the face to give more distance on mis-hits.
