ABSTRACT:
A racquet for hitting a projectile has a stem, which is a handle or a shaft with a handle, and a racquet head with a frame extending from the handle and supporting a tensioned string bed defining a sweet spot. The frame has an upper portion on an opposing end of the frame relative to the handle and a longitudinal axis extending from the upper portion to the handle. The string bed includes main strings generally running parallel to the longitudinal axis and cross strings running generally perpendicular to the longitudinal axis. The string bed has an upper end defined at an interior surface of the upper portion and a lower end disposed at an interior surface of a lower end of the frame near the handle. A length is defined from the upper end to the lower end of the string bed. The cross strings are only disposed at most within approximately an upper 70% of the length of the string bed.
