[Power-Seven]

XIOM beschreibt das so:

Omega 8 China:
X FACTOR Sticky for Forehand Drive
Chinese rubber stabilized in quality. Less weight than J&H C, but powerful performance. Softer X FACTOR sticky rubber developed by AI.

Omega 8 Hybrid:
Hybrid of Tension Rubber & Chinese Sticky
Hybrid with unique click feel and very speedy topspin. Low and powerful rebound from opponent's court to dominate the rally.

Der eine also mehr "klassisch chinesisch", der andere etwas "moderner".
