Claim Text:
1. A set of golf clubs comprising: a first club having a first club head, the first club head comprising: a first toe end, a first heel end, a first front end, a first back end, a first top wall portion, a first bottom wall portion, a first face portion associated with a first loft angle defined by a first loft plane and a first front end plane, the first front end plane is perpendicular to a first ground plane, and a first weight, at least a portion of the first weight positioned along a first axis extending between the first front end and the first back end; and a second club having a second club head, the second club head comprising: a second toe end, a second heel end, a second front end, a second back end, a second top wall portion, a second bottom wall portion, a second face portion associated with a second loft angle defined by a second loft plane and a second front end plane, the second front end plane is perpendicular to the first ground plane, and a second weight, at least a portion of the second weight positioned along a second axis extending between the second front end and the second back end, wherein: the first face portion comprises: the second face portion comprises: a first center of mass of the first club head is positioned at or proximate to a first distance relative to the first front end plane; a second center of mass of the second club head is positioned at or proximate to a second distance relative to the second front end plane; a first height is defined as a third distance between the first center of mass of the first club head and the first bottom wall portion of the first club head; a second height is defined as a fourth distance between the second center of mass of the second club head and the second bottom wall portion of the second club head; the first thickness profile of the first region of the first face portion is different than the second thickness profile of the second region of the first face portion; the first thickness profile of the first region of the second face portion is different than the second thickness profile of the second region of the second face portion; the first thickness profile of the first region of the first face portion is substantially equal to the first thickness profile of the first region of the second face portion; the second thickness profile of the second region of the first face portion is substantially equal to the second thickness profile of the second region of the second face portion; the first loft angle is greater than the second loft angle; the second loft angle is greater than 15 degrees; the first distance is less than the second distance; the first height is less than the second height; and the first distance is defined by a first equation of ((−0.0024*θ)+1.28)≧x≧((+0.0024*θ) +0.98), where the first distance, x, has units of inches and the first loft angle, θ, has units of degrees.
