Williams tech boss Sam Michael says it's a "no brainer" to run f-ducts in this coming weekend's Italian Grand Prix.
McLaren, Ferrari, Renault and Red Bull have all already stated that they may not run their f-ducts around the Monza circuit with all four expected to run tests during Friday's practice session before making a decision.
However, one team that can't understand why others would want to drop is the Williams outfit as Michael reckons the pay-off for using it far outweighs the cost of losing a bit of aero efficiency.
"I don't really understand why there is an F-duct issue (for Monza)," Michael told Autosport. "On the Monza wing we've got, there is a massive drag difference. I don't know why you would never do it.
"There is this debate that as you take drag off, it becomes less of a delta. That is true, but it is still a stalled wing so if the wing stalls then it stalls - for us it is a no brainer."
He added: "I think everyone will run it."
