Hi TS, i'm a user of T200 Apacs. I have recently switched to Lethal 90 (Fast Hex X-Section Frame Shape). What i would say is that Lethal 90 has slightly increased my game experience by its aero frame ability to swing faster. If you re looking for an upgrade, you can consider the lethal 90. In term of power, smash, i would say the lethal 90 is a better choice for me, as it gives a solid feel in hard smashing trust me if you get your hands on it. Of course, you must posses the right techniques in order to make good use of the racket features : )
, what do you want more of that your T200 doesn't quite give? What are you willing to sacrifice to get it? Those are the key questions that you need to answer before meaningful suggestions can be given.
