wherein a wall thickness in at least some areas of the heel portion is greater than the wall thickness of the center portion;
wherein an access for a hosel interconnection structure is in communication with and intersects the heel portion of the elongated channel;
wherein a ratio of the width of the center portion of the elongated channel to the depth of the center portion of the elongated channel is in a range between 3.5;
1 to 4.5;
1;
wherein the elongated channel has a front edge, a rear edge, and a width defined between the front and rear edges, wherein the width of the center portion of the elongated channel is substantially constant;
wherein the front and rear edges of the elongated channel are angled away from each other at the heel portion and the toe portion, such that the width of the elongated channel at the heel and toe portions increases from the heel end of the center portion toward the access and from the toe end of the center portion toward the toe;
wherein a rearward spacing measured from a bottom edge of the face to the front edge of the elongated channel is greater at the center portion than at least one of the toe and heel portions; and
wherein the wall thickness in the heel portion is greater in an area surrounding the access than the wall thickness of the center portion.

Abstract
A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball and a channel extending across a portion of the sole. The channel may be recessed from adjacent surfaces of the sole and have a depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion extending across a center of the sole, a heel portion extending from a heel end of the center portion toward the heel, and a toe portion extending from a toe end of the center portion toward the toe, wherein the width and the depth of the center portion of the channel are substantially constant, and wherein the depth of the channel is greater at the heel and toe portions than at the center portion.
