Hello people.. I would like to query those who owns both Yonex Muscle Power 55 and Yang Yang Tactic (8500 or 9000). Since the two rackets are famous and top of the line models, I am having a difficulty in comparing them in terms of power, control, durability...etc. So, I would like to make a favour: which one of the two rackets you like best? p/s: please don't tell me to buy the rackets, or tell me that it's your skill and strength that matters; i would just like to ask your true opinion based on your own experience. p/s: this is only a freelance question, no hard feelings!
