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.
This extra degree of strength allows for a thinner more flexible clubface and enhanced ball speed at impact. The thinner clubface along with a new hidden micro-slot in the sole not only increases COR but also expands the effective hitting area across a larger area. The micro-slot also allows for more weight to be redistributed for a lower and deeper CG location yielding improved launch on mid and long iron shots.
Featuring a blade-like clubhead with a small cavity and relatively narrow sole the Z 785 has more mass behind the sweetspot for improved versatility as well as a new Tour V.T. sole that improves turf interaction.
