Thank u all for your advice. I thought of the li Ning n80 but the frame is smaller no? Same as the arc z slash smaller frame not a forgiving racket.
N80 has a regular isometric head shape, different from the Arc Z-Slash, and compared to F9, it is more head-heavy and the shaft is stiffer as well. Since you mentioned that Arc10 is not head heavy enough, I think F9 would not be "the one" for you.
