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 fairway woods the Z-series hybrids are not adjustable but come in a selection of lofts including 16° 19° and 22° models. Project X HZRDUS Black 85 shafts and Golf Pride Tour Velvet 360 grips come standard.
The new TS2 features several design elements that contribute to making it significantly longer than the previous 917 D2 including an extremely thin titanium crown that’s approximately 20% thinner.
