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.
All of them feature the company’s signature RifleScope alignment technology. Happy also focuses on alignment by offering a customizable design. Bloodline putters feature a unique weighting design that allows the putter to stand up on it’s own so you can get behind the ball and check your aim.
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.
