hello sisters, finally after waiting for reviews of these two rackets according to your version. I've been using the Astrox 88D Pro for almost 9 months. In your opinion, between the Astrox 88D Pro and 77Pro, which part of the shaft feels stiff? especially I'm looking for a spare racket whose shaft is not so stiff. I'm thinking between 77 Pro and 11 Pro. In your opinion, between the 77 Pro and 11 Pro, which one is better, especially on the shaft, I'm looking for a shaft that is flexible, not stiff like the 88D Pro. Thank you
