Dimple patterns with surface texture for golf balls

A golf ball having an outer surface comprising a plurality of dimples, wherein at least one of the dimples comprises ten linear channels on the surface thereof;

• the ten linear channels comprising five linear channels of a first type and five linear channels of a second type;
• wherein each of the linear channels extends radially outward in a direction from the centroid of the dimple toward the perimeter of the dimple without intersecting the dimple's centroid;
• and
• wherein each linear channel of the first type has the same channel length L1 and the same channel width CW1, and each linear channel of the second type has the same channel length L2 and the same channel width CW2;
• wherein L1≠L2 and/or CW1≠CW2;
• wherein the first type of linear channel and second type of linear channel alternate about the centroid of the dimple;
• and
• wherein none of the ten linear channels intersect the perimeter of the dimple;
• and wherein the linear channels of the first type are spaced about the centroid by the same separation angle θS1 of 72.0 degrees, and wherein linear channels of the second type are spaced about the centroid by the same separation angle θS2 of 72.0 degrees.

A golf ball having an outer surface comprising a plurality of dimples, wherein at least one of the dimples comprises twelve linear channels on the surface thereof;

• the twelve linear channels comprising six linear channels of a first type and six linear channels of a second type;
• wherein each of the linear channels extends radially outward in a direction from the centroid of the dimple toward the perimeter of the dimple without intersecting the dimple's centroid;
• and
• wherein each linear channel of the first type has the same channel length L1 and the same channel width CW1, and each linear channel of the second type has the same channel length L2 and the same channel width CW2;
• wherein L1≠L2 and/or CW1≠CW2;
• wherein the first type of linear channel and second type of linear channel alternate about the centroid of the dimple;
• and
• wherein each of the twelve linear channels intersect the perimeter;
• and wherein linear channels of the first type are spaced about the centroid by the same separation angle θS1 of 60.0 degrees;
• and linear channels of the second type are spaced about the centroid by the same separation angle θS2 of 60.0 degrees.
