Bidahorria/Caparros project as the more stable pair in Bordeaux’s indoor/controlled P2 conditions, where structured point-building and clean volley selection are rewarded. Kurz/Fassio can disrupt with pace and first-strike aggression, but they’ll need sustained net control to avoid long, defensive exchanges. Slight edge to Bidahorria/Caparros in consistency and transition management over three sets.
