Dignics 64 is a low-trajectory, fast backhand rubber for blocking and spin insensitivity. Nittaku Fastarc C-1 is a forgiving high-arc tensor with outstanding spin and dwell time on opening loops. C-1 shares the G-1 topsheet for grippy, spinny performance, making passive blocks and mid-distance consistency excellent. C-1 offers strong value versus Tenergy 64 or 80 at a lower price.

Choose Dignics 64 if you block aggressively and attack fast. Choose Fastarc C-1 if you loop heavily and want forgiving arc and spin with premium tensor performance at lower cost. Both are excellent, but Dignics suits blockers; C-1 suits loopers.
