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.
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.
In addition both models feature an improved version of Titleist’s Active Recoil Channel technology in the sole creating more face flex particularly on low hits yielding higher launching lower spinning longer shots.
