I am not saying all other are equal, i highlighted what is the deal breaker for me and could be his. I owned 88D, 88S and VT80. All rackets plays differently and has their own characteristic. VT80 is a great racket to play with, excellent in many aspects. If only compare to 88D, VT80 is not as forgiving as 88D. Being both rated as stiff, 88D with new NAMD technology and rotational generator system, Astrox series feels a lot better when come into playing feel especially miss hit. I switched to Victors from YY 3 years ago with JS 10 and 12 and thought I would never go back to YY again but Astrox change my mind and now I am committed Yonex fan once again.
