Hi All, I'm currently using Voltric Z-Force stringed with BG66 Ultimax @ 27lbs. But i feel uncomfortable with this string setup. I noticed my smashes not as powerful as with my previous old racket. Abit stiff when time to smash. Can advise me for Voltric Z-Force, what string setup is recommended for an offensive player like myself ? I'm a mid intermediate player. Thanks in advance.
