The Callaway Tour i(s) golf ball is slightly softer than the i(z) and feels this way when you hit it. It feels great on and around the green and the hexagonal dimple pattern continues Callaway’s excellent reputation for golf balls that are more stable in the wind. The Tour i(s) is a much better ball than the previous Tour i not only because of the feel, but principally because it feels longer and is right up there with the best performers in this sector. That said, we think that the Tour i(s) will suit those who prefer a softer than average feeling ball, as the Tour i(z) has the feel/firmness balance just about right and would be our choice for most golfers.
