I was using my ARCS ZS TH (3UG5) yesterday for the first time. To my surprise, it didn't take me long to adapt to it maybe just one game. I was using the 8DX for 3~4 games and then switch to ZS on my 5th game. I was anticipating plenty of mishits due to the smaller sweetspot as mentioned by many forum members. I didn't encounter any mishits at all. IMO this racket is more powerful than the 8DX. In fact, I have managed to make a few incredibles net shot. I am really loving it. Will be getting another ARC ZS tonight in 2UG5.
