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.
As is the case with the drivers the TS2 fairway features a fixed CG location that’s low and deep for high launching mid-spin shots while the TS3’s CG can be customized via Titleist’s SureFit CG technology. In general the TS3 will produce a slightly lower trajectory than the TS2 and offers more shot shaping versatility.
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.
