Mena/Gonzalez Blanco look like the steadier, higher-ceiling pair in a FIP Silver setting, with more reliable point construction and likely better tolerance for long rallies. Aragon Herrera/Roglan Pons can upset if they speed the match up and win the first-strike exchanges, but they’ll need a clean serve/return phase to avoid being dragged into attritional patterns. Slight edge to Mena/Gonzalez Blanco in a tight match, especially if conditions are slower or heavier.
