In addition a thinner clubface which is six grams lighter and the fastest of any Titleist driver thus far significantly increases ball speed at impact. The new lighter and thinner face is actually so thin the scoring lines need to be created by a laser. If you’re looking for a combination of distance and forgiveness the TS2 could definitely be the ticket.
The Z 585 is slightly more forgiving and features a high-strength steel face insert in the forged clubhead for higher COR and ballspeed at impact. A new internal “speed groove” behind the clubface further enhances face flex across a larger area of the hitting zone for extra forgiveness on off-center hits.
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.
