A golf club includes a shaft and a club head. The club head includes a body member having a ball striking face, a heel, a toe, a rear and a crown. The crown may include a forward crown region, a rearward crown region, and a crown transition region therebetween. The rearward crown region may have a lower height than the forward crown region. The crown transition region may extend generally in a heel-to-toe direction. The vertical slope of the crown transition region may decrease as the crown transition region extends from the heel toward the toe. The crown transition region may lie at an angle from a front plane of the club head. Optionally, a club head may include a forward sole region, a rearward sole region, and a sole transition region therebetween.

1. A golf club head for a metal wood type club, the club head comprising: a body member including a ball striking face, a heel, a toe, a rear, and a crown,the crown including: a substantially horizontally-oriented forward crown region extending rearwardly from the ball striking face;a substantially horizontally-oriented rearward crown region extending forwardly from the rear, the rearward crown region having a smaller height dimension than the forward crown region; anda substantially vertically-oriented crown transition region extending generally in a heel-to-toe direction between the forward crown region and the rearward crown region,wherein the slope of the crown transition region decreases monotonically as the crown transition region extends from the heel toward the toe. 2. The golf club head of claim 1, wherein the forward crown region includes a portion that includes a convexly-curved surface, as viewed from a side of the club head. 3. The golf club head of claim 1, wherein a forward crown transition feature is formed by the intersection of the substantially horizontally-oriented forward crown region with the substantially vertically-oriented crown transition region, andwherein a tangent to the forward crown transition feature, measured at a centerline of the club head, ranges from approximately 0 degrees to approximately 25 degrees from a front plane of the club head. 4. The golf club head of claim 1, wherein a rearward crown transition feature is formed by the intersection of the substantially horizontally-oriented rearward crown region with the substantially vertically-oriented crown transition region, andwherein a tangent to the rearward crown transition feature, measured at a centerline of the club head, ranges from approximately 10 degrees to approximately 35 degrees from a front plane of the club head. 5. The golf club head of claim 1, wherein the centerline breadth of the forward crown region ranges from approximately 25 mm to 50 mm. 6. The golf club head of claim 1, wherein the centerline breadth of the rearward crown region ranges from approximately 30 mm to 60 mm. 7. The golf club head of claim 1, wherein the rearward crown region includes a portion that includes a convexly-curved surface, as viewed from a side of the club head. 8. The golf club head of claim 1, wherein the crown transition region has a centerline breadth that is between approximately 10% and approximately 25% of the breadth of the club head. 9. The golf club head of claim 1, wherein the slope of the crown transition region, measured at a centerline of the club head, ranges from approximately 40% to approximately 70% of the maximum slope of the crown transition region. 10. The golf club head of claim 1, wherein a height dimension of the rearward crown region, as measured at the rearward crown transition feature at a centerline of the club head, ranges from approximately 50% to approximately 80% of the height of the club head. 11. The golf club head of claim 1, wherein the height dimension of the rearward crown region, measured from the heel to the toe along a line located at 60% of the breadth of the club head from the front plane, varies by less than ±20% from the height dimension of the rearward crown region measured at 60% of the breadth of the club head at the centerline of the club head. 12. The golf club head of claim 1, wherein the club head breadth is greater than or equal to 12.0 cm, and the club head length is greater than or equal to 12.0 cm. 13. The golf club head of claim 1, wherein the height of the center of gravity of the club head is less than or equal to 1.75 cm. 14. The golf club head of claim 1, wherein the body member is a square head member. 15. A golf club head for a metal wood type club, the club head comprising: a body member including a ball striking face, a heel, a toe, a rear, and a crown,the crown including: a forward crown region extending rearwardly from the ball striking face;a rearward crown region extending forwardly from the rear, the rearward crown region having a smaller height dimension than the forward crown region, wherein a difference between a height of the rearward crown region and a height of the forward crown region is 5 mm to 30 mm; andan elongated crown transition region extending between the forward crown region and the rearward crown region and generally extending in a heel-to-toe direction at an angle that ranges from approximately 5 degrees to approximately 40 degrees from a front plane of the club head, wherein the elongated crown transition region has a slope that decreases monotonically as the crown transition region extends from the heel toward the toe. 16. The golf club head of claim 15, wherein a majority of the surface of the rearward crown region is a substantially convexly-curved surface. 17. The golf club head of claim 15, wherein the maximum height dimension of the rearward crown region is less than the minimum height dimension of the forward crown region. 18. The golf club head of claim 15, wherein the crown transition region is located within the middle 50% of the breadth of the club head.
