Check them out and see if one is right for you but keep in mind the TS2 is aimed at those who want high launch low spin distance and forgiveness while the TS3 is aimed at those who want mid launch low spin and enhanced workability.
This improvement saves weight and lowers and deepens the CG for improved launch and carry distance. As a result of the weight savings in the crown and variable thickness clubface the TS2 actually features the lowest CG of any Titleist driver to date increasing MOI over the previous 917 D2 by as much as 12%.
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.
Aimed at low-handicappers and pros the 919 Tour model replaces the 900 Tour a.k.a. the Brooks Koepka model and features an improved shape with a bit thinner topline that the many Tour players who game the iron prefer. A new more durable Pearl Brush finish reduces glare while providing a bit more refined look than the previous matte finish.
However it’s also fair to say that the company’s handsome big sticks were somewhat known for being a bit shorter than those of some competitors due to slightly higher spin rates and a design aimed at more control.
