The Bluestar A2 is a softer version of the Bluestar A1 rubber. Sponge hardness
of the A2 goes down from 52.5' (A1) to 50' (A2) giving it more dwell time and
making it less fast and less "throwing". The sponge is equipped with small pores
and makes Bluestar different from all other Donic rubbers. A grippy top-sheet
makes it possible to control the trajectory of strokes well. Perfect rubber for
players who rely on feeling but need additional power for the winning shot. A
perfect rubber for aggressive play with a degree of feeling, that demands
practice to be able to use.
