A golf ball having a North pole and a South pole, an equator and a primary meridian, the equator and primary meridian divide the ball into North, South, East and West hemispheres, and Northeast, Northwest, Southeast and Southwest quadrants. A grid pattern projected on the ball surface divides the ball laterally and longitudinally into a number of overlapping zones. The dimples within the zones have average depthsex,sx,px,ei,si andpi and selected values of Δe, Δs and Δp which are the difference between the minimum and maximum values of the relative ratios of the dimple depths,ex/ei,sx/siandpx/pidetermined when the ball is rotated by a value of θ from 0 to 360° about its polar axis.

Disclosed golf club heads include a body defining an interior cavity, a striking surface, a sole, a crown, and a hosel, which is configured to provide improved aerodynamic and inertia generating properties of the golf club head. Certain embodiments include an inertia generator positioned in the sole between an area proximate the club head's center of gravity and a position toeward of the center of gravity at the rear of the golf club head. Some embodiments include fixed or removable mass elements, weights or weight assemblies positioned in the sole, including, in some instances, within or adjacent to the inertia generator. In particular embodiments, one or more weight assemblies are movably retained within a weight channel defining a path along the sole.
