After many years of playing experiences, anyone can share about any rackets you feel is fast yet performs like a rocket launcher?
Nanoflare 800. Easy to play, it is actually a very good racket for immerdiate players who play double.
Yonor BS II and Vinex ZF 12 are the obvious standouts. But then there's the problem of availability...
Welp, compact head is a point but NF800 is probably not any stiff. I played her myself as an ordinary level player. Badminton Racket Review measured NF800, the stiffness was flexible. :v
