A considerably thinner upper rubber, which is under correspondingly high tension, leaves room for a thicker sponge, which brings even more power. The Bluestorm offers noticeably greater dynamics with the same spin and speed characteristics, which is a sign of the trend. The thinnest sponge here has 1.9 mm, the middle sponge thickness is 2.1 mm – and the thickest version is called max +, because this sponge is even thicker than in the usual Max versions.
DONIC Bluestorm Z1: The lightning stroke
The Z1 with a medium-pored sponge and a short, wide nub structure is the hardest and fastest of the three Blue-Storm versions. He has huge power, but to use a lot of horsepower, a good driver should be at the wheel. If you train a lot and master the fast game accordingly, the Z1 is a powerful weapon. Topspins with this topping beat like the flash!
