Hewei Yoshida and Ebony Seven are both positive gums, but their properties are different.
Yoshida Haiwei's positive glue is fast and powerful, which is suitable for near-table fast break and topspin. If you like to attack quickly, then Yoshida Haiwei may be a better choice.
The positive glue of ebony seven pays more attention to control and stability, which is suitable for cosco's pulling and backspin. If you prefer to control the rhythm of the game, then ebony seven may be more suitable.
