    摘要: The invention is directed toward a trial golf club head and method for determining the optimal loft angle for any golf club, and in particular a hybrid-type golf club. The invention includes a trial golf club head having a face portion, a leading edge portion, a toe portion, a heel portion, a back portion having a trailing edge portion, and a sole portion. The sole portion contains a number of equally spaced graduated indicia, which are substantially parallel to one another and extend from the toe portion to the heel portion. The distance between the graduated indicia is approximately 3.75 centimeters (cm), which corresponds to an incremental loft angle of approximately 3 degrees. The sole portion has a radius of curvature of 71.67 mm, which extends from the leading edge of the face portion to the trailing edge of the back portion.
