Hello. I am just about to purchase Victor Limited Edition Lee Yong Dae Brave Sword Badminton Racket. I would like to ask you questions about this racket. 1. For racket weight, I am thinking 4U(80g-85g). I just feel that it would be better because Victor LYD bravesword racket is head-heavy racket so why not go for bit lighter weight? 2. Is Yonex BG 80 similiar to VS 850 power string? Is it okay to use yonex string on victor racket? 3. For string tension, should I go for 23lb or 24lb or 25lb? I do play badminton twice per week and I would consider myself as intermediate or advance player. I only play doubles with my friends. My friends are telling me that I do have strong smash, good control and not too bad in defense. I also want to improve on defense so can you please tell me which string tension should I choose? I would like to hear your answers as soon as possible. Thanks!
