Hi guys. I think I read somewhere here that if you put lead tape on Yonex Rackets at around 10 and 2 it would improve it and unlock super special powers . Lol your racket turns into like a samurai sword. Well it is japanese ,so you never know. But really, Does anyone remember reading this or perhaps has benefited from your it. I play with the ezone xi 98 with poly tour spin 60/58. Thanks. Would love to test it out. Yonex users, where do you put lead, how much, and how long??
