Abstract
Games racquets used in games such as tennis, squash and racquet ball normally comprise a head, a bridge, a throat and shaft area plus a handle. The deemed mid section of the frame of the games racquet includes the majority of the bottom half of the racquet head, the bridge, the throat, the shaft, and possibly some small proportion of the handle. The deemed mid section of the frame of the games racquet is manufactured so as to account for only twenty five percent (25 %) or less for tennis and twenty percent (20 %) or less for squash and racquet ball of the total weight of the unstrung racquet. This allows the remaining weight to be distributed in varying proportions near opposite ends of the games racquet thereby setting up a counterweight balancing system of large proportions.
