1. A golf ball having an outer surface with a number of dimples thereon and having a north pole and a south pole, an equator and a primary meridian, the equator and primary meridian serving to divide the ball into north, south, east and west hemispheres, and a northeast, northwest, southeast and southwest quadrant; and wherein a grid pattern on the ball surface forms a number of overlapping zones, said zones comprising;
A) an equatorial zone, E×N, in the northern hemisphere between the equator at f=90° and a line formed by a plane parallel to the equator at f=65°;
B) a shoulder zone, S×N, in the northern hemisphere between the line formed by a plane parallel to the equator at f=65° and the line formed by a plane parallel to the equator at f=25°;
C) a polar zone, P×N, in the northern hemisphere formed by a plane parallel to the equator at f=25°;
D) a region, NEiE, in the northeast quadrant defined as collectively two regions, the first between the primary meridian arc at q=0° and the great circle arc at q=25° and the second between the great circle arc at q=155° and the great circle arc at q=180°;
E) a region, NSiE, in the northeast quadrant defined as collectively two regions, the first between the great circle arc at q=25° and the great circle arc at q=65° and the second between the great circle arc at q=115° and the great circle arc at q=155°; and
F) a region, NPiE, in the northeast quadrant defined as the region between the great circle arc at q=65° and the great circle arc at q=115°; and wherein;
G) an average depth of the dimples in each of the E×N, S×N, P×N, NEiE, NSiE and NPiE zones in the northeast quadrant is defined as hex, hsx, hpx, hei, hsi and hpi respectively; and wherein
a) the golf ball has a total number from 275 to 475 reduced equivalent depth dimples on its surface; wherein
i) from 5 to 9% of the total number of reduced equivalent depth dimples lie in the NEiE region, from 5 to 10.6% of the total number of reduced equivalent depth dimples lie in the NSiE region, and from 5 to 7.1% of the total number of reduced equivalent depth dimples lie in the NPiE region;
ii) from 5 to 9.6% of the total number of reduced equivalent depth dimples lie in the E×N zone in the northeastern quadrant;
iii) from 10 to 14% of the total number of reduced equivalent depth dimples lie in the S×N zone in the northeastern quadrant; and
iv) from 1 to 3.1% of the total number of reduced equivalent depth dimples lie in the P×N zone in the northeastern quadrant; and
b) the golf ball has greater than or equal to 3 different dimple diameters each of which are from 1.0 to 6.5 mm;
c) a depth of the reduced equivalent depth dimples are each from 0.06 to 0.200 mm;
d) the average depth of the dimples in each zone in the northeastern quadrant, hex, hsx, hpx, hei, hsi and hpi are each from 0.060 to 0.200 mm;
e) the depth ratio in the northeastern quadrant hex/hei, hsx/hsi, and hpx/hpi are each all greater than or equal to 0.75 and less than or equal to 1.20; and
f) a total dimple volume, TDV, is from 380 to 500 mm3.
