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.
The newest version also features a forged construction similar to the Z 585 and Z 785 irons but is built with a hollow club head and high-strength face insert that allows the club to behave more like a wood. What this means is higher launch higher flight and more distance for a wide variety of players.
Other features include a low compression core for excellent feel and low-spin distance on long shots and a 338 speed dimple pattern for less drag improved launch and solid performance in windy conditions. Less sidespin for straighter shots is an additional benefit a wide variety of players will appreciate.
In addition the Z 785 comes stock with the exceptional Project X HZRDUS Black shaft which is hand made in San Diego for the utmost consistency (fyi – they go for about $300 in the aftermarket). For those considering this good-looking new stick it promotes a more boring low-spin trajectory and enhanced workability over the non-adjustable Z 585 model.
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.
