Hyper Elasto technology rubber upgraded by new chemical composition and new Carbo Sponge. Solid ball-capturing at the surface and perfectly matching sponge hardness promote extra spins and superb control. OMEGA IV EUROPE produces significantly higher ball trajectory to make a bigger window over the net. OMEGA IV EUROPE stretches the ball from opponent's court aggressively as if launched from speed-glued rubber. Clicking sensation at the ball contact also reflects the maximized built-in tension simulating full speed-glue effect.
