Hi Communitiy, i have a question and hoping to find an answere here... The manufacturers produce the same racket in different weights. For example Yonex U3 and U4. My question is, if the lighter U4 and the heavier U3 version is just a result of the thickness of the grip, or come the weight difference from diffences in the frame??? In other words, is the extra weight of the 3U only in the grip? So if the wooden grip would be cut of the racket, would be the U3 and U4 frame the same or different weight? That the weight difference results just out of the thicker/thinner grip would be logical for me, because 1.) The heavier 3U alwasy come with the thicker grip, and the 3U always with the thinner grip. 2.) I hardly can believe, that the manufacturer designs and produce in the high end line of rackets frames with two different weights... It would be a big extra work... On the other hand some people say, that playing a 4U is completely different than a 3U racket, which can´t be, if the extra weight of the 3U is only in the grip... Thanks in advance for any feedback!
