What we say...
Mizuno reckon previous moveable weight drivers have been difficult to hit because the mass taken up creating the ports, weights and tracks raises the cg and moves it closer to the clubface. Their solution is the JPX EZ which has a simple 3 track weighting system and single 10g weight to offer the same levels of forgiveness as a non-adjustable model.
The three track adjustability offers a fade, draw or neutral bias so you can tailor ball flight to suit your game. Mizuno’s engineers have created a lightweight chassis inside the head which allows for the creation of the slide tracks and weight which also help improve moi. The whole set up means weight is positioned low and deep which for golfers means a high forgiving ball flight.
A larger clubface and front to back profile mean the JPX EZ have a larger more stable footprint which aids playability. Mizuno also reckon the rounded crown of the JPX EZ helps increase face flex particularly for slower swing speeds and off centre hits, whilst a “Quick Switch” hosel allows a 4 degree loft range adjustment.
Don’t expect to see these in golf shops until early 2016. When they do appear you’ll have the choice of a 10.5 deg loft with either a Fujikura Orochi or Fujikura Six shaft as standard.
