Both are rated 8.4 and deliver exceptional value against premium Butterfly alternatives. The M2 is a lively, backhand-friendly medium-hardness tensor with strong catapult response to boosting; Fastarc C-1 is a forgiving all-rounder with outstanding spin and dwell on opening loops, a shared G-1 topsheet, and a high safety-margin arc. M2 suits intermediate-to-advanced loopers who play close-to-mid distance and value a high arc; C-1 suits intermediate-to-advanced offensive players (especially backhand users) who want premium tensor spin without the unforgiving demands of harder rubbers. M2’s bouncy nature can betray short pushes and passive blocks; C-1 excels at effortless passive blocks and consistency. Pick M2 if you boost and want responsive catapult; pick C-1 if you prioritize spin consistency and forgiving feel over raw top-end speed.
