the better answer would be: speeeeeeeeeeeeedddddd. and lots of it. most of the superlight rackets are quite fast, which is a boon around the net.
however, most would lack in power, whether outright or regular. Also, there is the off chance that there would be stability issues.
Okay, this might be my very first time hearing if an actual 6U & 7U racket exists! I once heard there is 5U version of racket (pretty sure it ain't The-Big-Three; Yonex, Victor, & LiNing), but 6U & 7U, how does it feel playing with feather-weight racket? Please enlist me some of the rackets that have 6U & 7U version. I'm curious as to try 'em.
^^ Yes, but you will reach a point where the speed advantage of light rackets reaches the limit of human muscles; and from that point onwards, you will need to add mass to transfer more momentum onto the bird.
Essentially what visor mentiond has captured the main idea. I have covered this topic many times, but i guess no harm in writing it again.u sound reasonable, any1 else have any ideas?
Good point, a lighter racket often vibrates more and more mass it vibrates less. But I think its not only related to its weight. String, grip, shuttle, grommet, BP, stiffness, T-joint, cone, etc all can contribute to a racket vibrationAnd how about vibration ?
