Hello guys, I am planning to buy a Yonex Voltric Z-Force 2 racket. I have never bought a racket before so I am not sure how much tension and what type of string I should buy. I would say I am an intermediate player. I like to be offensive player and I like power and control. I am thinking of buying a Nanogy 99 string with ~24lb tension. Any tips or suggestions on string and tension? Thanks for helping!
