Golf balls including at least one modified dimple group are disclosed. The modified dimple group comprises one or more modified dimples forming an axially symmetric pattern about a Correction Area Centroid located on an axis of symmetry at a latitude greater than 0° , where 0° represents the hemispherical pole and 90° represents the equator. The modified dimples can be altered, for example, by changing dimple coverage, dimple diameter, dimple depth, dimple edge angle, dimple volume, dimple cross-sectional shape, and/or dimple plan shape. Optionally, the dimples have a catenary cross-sectional shape and the modified dimples are altered by changing the shape factor and/or chord depth. Such modifications preferably produce a golf ball that flies more consistently regardless of orientation when struck than a corresponding golf ball without such modifications. |

1. A golf ball comprising a plurality of dimples forming an overall dimple pattern on the outermost surface of the golf ball, wherein the golf ball consists of two hemispheres, each hemisphere consisting of two first regions and two second regions, the two first regions having an identical first dimple pattern and the two second regions having an identical second dimple pattern, wherein each of the first dimple pattern and the second dimple pattern comprises a plurality of unmodified dimples having a circular plan shape and at least one modified dimple having a non-circular plan shape selected from the group consisting of polygonal, oval, and irregular plan shapes. |
