Choose Fastarc C-1 for its predictable high arc and forgiving dwell time on loops and blocks. Choose Rakza X (8.4 rating) for a firmer, more linear response and higher topsheet grip, especially if you want a fast tensor that still handles short-game touch well.

Rakza X is the harder, grippier option with a predictable trajectory that rewards committed strokes. Both are rated equally (C-1 at 8.4), but Rakza X is heavier (69 g vs 47 g uncut) and suits offensive players wanting more grip without sacrificing control. Fastarc C-1 is lighter, safer on mishits, and better for players who like dwell. Rakza X is the upgrade path if you loved Rakza 7 but want faster play and more linear feel.
