A rubber by professionals for professionals - and for everyone who places professional demands on their material. The newly developed nub rubber compound ensures a direct hit and excellent feedback when hitting the target. The sponge provides an extremely good catapult effect. But the most important recipe for success is the special composition of the upper rubber, which perfectly supports topspins even under difficult conditions. Result: The Bluestorm Pro is extremely dynamic and grips optimally even with very thin balls. The Bluestorm Pro Am, with a slightly softer sponge, impresses with the perfect balance between dynamics, control and rotation The control is extremely good with both variants in active and passive play, which is also due to the strict selection process: strict selection in terms of weight and sponge hardness minimizes series fluctuations and ensures consistent quality at a high level for each individual rubber.
