I really like the feeling of TKF-enhanced and I have two of them. However, with recent bad experience with Victor claim process, I am thinking of moving toward Yonex. However, I am not sure what racket on Yonex side has the similar feeling. My first guess is Astrox 77 pro. However, I used to use the blue Astrox 4u4g before and it feels too sluggish while I heard that Ax77 red OG, or Ax77 pro are faster racket. Please advice, thanks.
