The Z 785 driver is revolutionary for Srixon for a number of reasons but mostly because it produces up to 3 mph more ball speed than the previous model yielding up to ten more yards of total distance. The key to the impressive improvement is a new Ti51AF Cup Face which is lighter and significantly stronger allowing it to be made 10% thinner for more COR and ball speed at impact.
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.
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.
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.
None of the above matters if you can’t aim your putter correctly Experiment with offset and straight-in hosels — you’ll definitely aim one type better than the other. Then check the alignment marks. Do you prefer lines that run parallel to the target? How many lines? These are important questions that can best be answered through a proper fitting.
