Hi All, Anyone tried the new version of Victor Auraspeed 90k 2? Please share here your experience using a 3U and 4U. What is the difference in terms of playing with the original version? I plan to get another 3U version of the AS90K first version so I can use them alternately during matches but I am also thinking if I just get a 2nd AS90K 2nd version racket and that way I can feel the difference. The 2nd version usually is the upgrade of the old version but sometimes it may not be a good upgrade too. Your thoughts please thank you.
