Geens/Guichard look like the more complete pair for FIP Silver tempo: Geens’ control and countering should stabilize rallies while Guichard adds weight on the smash and speed in transitions. Courrin/Seux can trouble them with early net pressure and fast point endings, but over longer exchanges they’re more likely to leak errors under Palermo heat and lively balls. Slight edge to Geens/Guichard in two tight sets if they win the middle phase and protect their serve games.
