DONIC ACUDA BLUE P1. Donic Acuda Blue P1 is meant for all out attackers and you will find it a pleasure to play with. ACUDA BLUE P1 has a 50° medium hard sponge, the latest in sponge technology. This blue sponge with medium sized pores is softer than previous sponges, despite having a higher degree of hardness. The rubber topsheet features a new pimple geometry, thin long pimples with extra space between individual pimples. The rubber topsheet is of the latest generation which is very grippy, as with Bluefire M1 Turbo and JP 01 Turbo but with slightly flatter ball arc.
