Mizuno’s Swing DNA System records 40 unique data points from more than 175,000 golfers every year – providing the basis for every JPX iron project.

Mizuno Shaft Optimizer

“We’re constantly evolving the JPX series based on more than 175,000 unique swings we capture every year on the Mizuno Shaft Optimizer. Recently we’re seeing an increase in the number of players with slightly slower swing speeds being fitted - and a trend to more shaft lean. Hence a slight increase in bounce angles through all the models and the introduction of the Hot Metal High Launch”
