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 TaylorMade Spider Tour Red for example, has a Pure Roll insert designed with 45° grooves that add topsin to get the ball rolling true as soon as possible. Another benefit of the Pure Roll insert is that it gives off a quieter sound and a softer feel compared with other inserts in TaylorMade's range.
