The Nittaku Fastarc S1 is the softest and together with the Fastarc P1 the fastest rubber of the series.
The slightly softer sponge with 44 ° and the grippy top sheet with pimples further apart has a strong catapult. The softer combination of the surface and the sponge result in a flat trajectory. The momentum of the rubber is high. Because the rubber can be strongly compressed, this rubber is a bit harder to control during fast rallies. However, the feel and control is very good on softly pulled topspin.
