Callaway Tour I(Z)

Golf Monthly Verdict

Callaway have again created the softest feeling ball on offer in the form of the Tour I(S). This could prove particularly useful now that the groove rule is in place. The soft cover on Callaway Tour I(Z) & Tour I(S) does mean they have more of a tendency to cut up.

Callaway's HEX Aerodynamics replace standard dimples on the Tour I(Z) and help reduce drag for a stronger flight on long shots. The 4-piece design includes a dual core that helps increase distance for a wide range of swing speeds.

The new grove rule has meant that Callaway have made their Tour I(S) ball even softer to help provide added spin from short-range.
