2.O circle limit is equivalent to mechanical intervention earlier than 4.0 racket head
3. The impact position is optimized and the center area is protruded to prevent the outer ring from being stressed.
4.POM is lightweight and reduces high-speed inertia
5. Changed from 4.0 split to one-piece design, higher shooting limit
