Leal/Guerrero should have the higher ceiling in Rome-style major conditions: heavier balls reward physical defense, structured transitions, and controlled aggression. Collado/Hernandez can compete if they speed up with early volleys and take time away, but in long exchanges Leal/Guerrero look better built to impose. Prediction: Leal/Guerrero in a tight two sets or three, edging the key points with superior reset-to-attack patterns.
