This racquet confuses me because I read some reviews that this racquet is comfortable, and some reviewers says that it is notSorry you misunderstood me. Ezone 100 is still more comfortable than pure aero/pure strike 2019 versions. No pain/soar/fatigue on my arm/elbow. It’s totally fine. I only wrote that it plays firm on ball contact like previous ezone. This racquet has nothing in common with DR line and i don’t know why TW testers mentioned it on their review. Dr/Ai/Xi versions are still the king.
