Fastarc C-1 features a softer 45-degree sponge with outstanding spin on opening loops, forgiving high arc, excellent passive block consistency and controlled mid-distance power—ideal as a backhand rubber or forehand allround option. Fastarc G-1 has a firmer 47.5-degree sponge, heavy spin combined with real speed on either wing, Tenergy-like durability and a proven popular all-court attacking style, though it requires more committed and technically sound strokes.

Choose C-1 if you loop heavily, prioritize arc and consistency over raw speed and want premium tensor spin on a softer sponge. Pick G-1 if you want a heavier-spinning, slightly faster rubber with exceptional durability for either wing attacking—it’s the versatile choice for intermediate-to-advanced players, though the firmer sponge demands better technique.
