I am abit confused with the definition of swing weight of the tennis specs. The tenniswarehouse definition has it as "Measure of how heavy a racquet feels when swung, i.e. maneuverability. Also known as Moment of Inertia or Second Moment". I am not sure i see the correlation between how heavy a ball feels and maneuverability of the racquet, although I have found that racquets with lower swing weights are not as manuverable. Also, does swing weights have anything to do with how "freely" a racquet swing through the air. I notice some racquets with high swing weights such as the prestige, diablo, and other players racquets have high swing weights and can be swung smoothly even though its wait is high. This as opposed to playing with an oversize, which i am accustom to, and not finding the racquet swing as smooth through the air. Any advice will be appreciate. Thanks.
