Edwards has used the French rubber in his entire MotoGP career and won his two World Superbike titles with them in 2000 and 2002 with Honda. He's also done thousands of miles of testing with Michelin technicians.
But when I asked Lin Jarvis if Yamaha were talking to Bridgestone - just one of the rumours seething round the pits here - he confirmed this.
"It's not 100% clear what we will be doing," he said. "We would like to continue with Michelin in the future, but there have been discussions with
Bridgestone. It's quite clear that Bridgestone riders at this moment have an advantage. At the moment we are in deep discussions."
Saturday pm - Stoner Puts the Big Calm on MotoGP
Casey Stoner unintentionally summed up this weirdly calm season of MotoGP racing when he said, after wrapping up his third consecutive pole position here at Brno: "Even when things are not working perfectly, we still end up with a good result."
And it is calm here - totally becalmed. The buzz that normally hangs over this paddock isn't there.
Nicky Hayden has just scored his first front-row start on the Repsol Honda, but he's way past being a championship threat. His team-mate
Dani Pedrosa got his seventh pole of the year, but he's now so far behind that in the points that he also can't seriously run for the title in these final seven races of the season.
Everyone's assuming that Stoner and Ducati will now just roll onto the first world championship for both the factory and the rider. It's odd now to think that only a couple of seasons Ducati were thought of as those wonderfully mad Italians who could put together two or three wins in a season, but nothing more serious than that.
Everyone at Ducati is denying that there's any tension in the team and that they don't yet talk about winning the championship. "We all know it's possible," Stoner said. "But we don't say, 'We'll keep this setting because it's good for the championship'.
