wherein the plurality of first grooves extends a depth D1 into the club head, the plurality of second grooves extends a depth D2 into the club head, and the recesses extend a depth D5 into the club head;
wherein D1, D2, and D5 are measured in a direction perpendicular to the ball striking face;
wherein D1 is greater than D2; and
wherein D5 is at least two times greater than D1.
