This pairing looks like a classic contrast between a steadier Spanish-style build (Canovas/Rodriguez) and the more opportunistic, punchy axis you often get with an Italian-Spanish duo like Marchetti/Borrero. In a FIP Gold context, Shanghai conditions typically reward first-strike efficiency and clean transitions, nudging the edge toward the pair that converts short balls faster. Slight lean: Marchetti/Borrero in tight sets if they win the net battles early; otherwise Canovas/Rodriguez can grind them down.
