Clubface with zero roll produces a higher launch angle on shots hit low on the face, increasing distance with softer landings.
Precision shaping of the face thickness in each club increases the size of the sweet spot, generating hotter ball speeds for longer distance.
Increased head size of the standard model creates better forgiveness, producing shots that fly higher, longer and straighter.
The Tour models have less offset, giving skilled players the versatility to work the ball more easily.
