Unlike driving off the tee or hitting into greens when they have to consider the wind, club selection and much more, on the greens, like Carnoustie’s 18th (above), all the pros have to worry about is line and speed. The latter relies on getting the ball rolling quickly and smoothly, which is helped by the faces on modern putters.

The PING Vault 2.0 Voss for example, has an individually milled True-Roll face pattern that varies in depth across the face. This design helps speed up putts struck off-centre so fewer putts finish short of the hole. After all, it doesn't matter if your putt's on line if it comes up short.
