As one would expect from a Mizuno blade the 919 Tour features a Grain Flow Forged HD (high density) construction from1025 Elite carbon steel for the soft responsive feel aficionados demand.
Also new in the Z woods family are the Z 585 driver a non-adjustable model with the same distance-inducing technologies as the Z 785 as well as Z F85 fairways and Z H85 hybrids.
Since then however the JPX 900 models most notable the Forged Tour have been a huge hit with all kinds of players including two-time US Open champ Brooks Koepka.
A significant key to the Hot Metal design is the use of stronger and more expensive Chromoly rather than carbon steel in the manufacturing process. The stronger material allows for a multi-thickness cup face for more ball speed and distance than the previous 900 Hot Metal as well as redesigned sound ribs in the cavity for precisely tuned vibration and feel at impact.
Like the TS2 the TS3 features the same thin titanium crown for lower and deeper CG location thinner and faster clubface for more distance and improved aerodynamic shape for more swing speed.
