Same. I just bought the Aeon last week and wore it for the first time yesterday. It was in the mid to high 80s, and I did a nice 40-mile ride. It was super breezy, so I wasn't aware of the ventilation difference between that and my Lazar helmet, but it's noticeably lighter, which I really appreciated.
