Hi, I am a doubles player who likes to smash, but also likes to play net. I tried my friend's Windstorm 72 by Li Ning and I like how lightweight it is. I am looking at the Windstorm 500 right now and it seems like a good choice considering i liked the 72. Has anyone used it? If so how is it? Also I am looking at strings and deciding between the Li Ning no. 1 or the BG65TI by Yonex. Both will be strung at 23lbs. Thanks in advance.
