Pluto is, depending on your point of view, a short medium-length bump or a longer short bump, but with a predominant tendency to a medium-long bump. The bumps are remarkably wide. Also, the bumps are slightly fluted, but noticeably less grippy than e.g. with the Friendship 563-1. The ball attack is rather hard. Pluto can be easily controlled at its medium speed. It provides more interference than short bumps and creates a dangerous and flat ball flight curve for the opponent. This flooring is optimally suited for a typical counter and block play. A rather medium elasticity and a lower catapult effect, on the other hand, make this surface seem rather unsuitable for a modern and spin-oriented offensive game.
