One of the somewhat surprising successes for Srixon in recent years was the Z U65 utility iron which very nicely blended the distance and versatility of a hybrid with the added control of an iron.
Other features of the new Hot Metal include the aforementioned “stability frame” design for higher MOI and improved launch as well as Mizuno’s new Pearl Brush non-glare finish.
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.
There are differences however including most notably more adjustability in the form of Titleist’s SureFit CG technology that allows for more specific spin rate and launch angle tuning. The TS3 also features a more traditional pear shape and tends to produce more of a mid-launch as compared to the TS2’s higher launch.
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.
