F-duct debate drags on ahead of Monza

Many teams are yet to decide on running their F-duct at this weekend's Italian Grand Prix at Monza, as they look to balance the pros and cons of using the device on the quickest track on the calendar. While Red Bull, McLaren, Ferrari and Renault are all considering their options, other teams, including Williams, are expected to run the F-duct.

Speaking a fortnight ago about using the F-duct at Monza, McLaren's managing director Jonathan Neale said the team would wait until they had data to hand from the Belgian Grand Prix to make a decision. "We have the option to run it or not," said Neale. "At the moment we're just looking at all the options. We'll watch carefully where the end-of-straight speeds come out at Spa."
