The FASTARC C-1 is designed for offensive play, featuring a softer sponge compared to the G1, with a hardness of approximately 43° and enhanced catapult effect. The top sheet’s closely spaced pimples provide a firmer stroke. This combination results in good speed, although the slightly softer sponge produces a lower trajectory and slightly less spin compared to the Fastarc G1. Despite this, the C-1 offers higher momentum, making it a dynamic choice for aggressive play.
