I hope someone can explain this for me. My limited understanding of racquets says that when comparing two racquets that have equal or very close strung weight and balance the swing weight of the two racquet should also be equal or close. Is this right ? To be more specific based on TW specifications, comparing LM prestige MP to RDX 500 mid, both have very close strung weight as 11.9oz. and 11.8oz respectively. Also the balance is the same. But, the swing weight is very different, 325 vs. 318. I have both racquets and when I swing the racquets I can empirically feel the difference in sw. There is got to something that I am not understanding correctly or missing. Could the experts on this board help me understand ?
