Marchetti/Arruabarrena project as the more structured, high-percentage pair: Arruabarrena’s control and experience should stabilize the left side while Marchetti can finish in transition. Borrero/Baldi are likely to be more streaky—dangerous if they win early net exchanges, but vulnerable if forced into long, patient points. In FIP Silver conditions, the safer bet is Marchetti/Arruabarrena via superior shot selection and better management of golden points.
