The rubber surface of the MX-P50 HARD version is identical to the rubber surface of the already familiar MX-P (47.5). The professional players have already had this high-performance harder sponge available to them and due to the new generation of plastic balls, and now Tibhar is making this available for all players. The professional players have the choice between fine-pored and open-pored sponges, currently the MX-P (47.5.) is open-pored but now Tibhar is releasing the fine-pored variation, which is MX-P50 HARD. This fine-pored version plays noticeably differently with an increased forward and direct motion.
