I've tried it in all the conditions that caused issues before as well as some triple digits and I'm happy. I still use the Aeroflow long rides for the wind blocking and noise.
I have come to the same conclusion about the Arai helmets. The bill just is not stiff enough. I am looking to have a carbon fiber version. That should fix the problem. I will report the results when done.
