haha not that strong wan try only, why fu haifeng use mid flex and almost even balance racket to generate awesome smash. im curioussss~~~
for personal opinion, i tried to hold and dry swing kason F9 before, the feeling is like swinging Arc10, but the head is lighter than arc10, swinging is faster than arc10... something like Arc Z slash but definitely better than arc z slash... now i waiting VT Z Force LTD 4UG5 olympic edition.. then my next racket will be Kason F9.
wahahaha u sure collect many racket eyh alan. me too would love to get my hands on F9 as im used to head heavy racket, want to try something different this time.
