currently i'm using Apacs Lethal 85 which is BP 285 (head light) & medium flex, and it is very suit to my style of playing... now i'm thinking of to change to those two rackets which are Apacs Tweet 8000 International or Kason F9... actually my spec is BP 295 (little bit heavier than prev racket) & medium flex... i had hold these two rackets without string n try to feel the flex and BP & feel like the Apacs was little bit head heavier & stiffer than F9... now only the price is the issue where the Tweet i can get rm320 and the F9 for rm500... i need to hear your suggestion or anything u wanna say about these rackets... thanc for reply
this F9 thread is what u are looking for. http://www.badmintoncentral.com/forums/showthread.php/108581-Kason-twister-F9-review
tweet 8000 is much more heavier than your lethal 85. Go for tantrum 500, it is medium stiff and slightly head heavy, just suit your requirement.
