Just to chime in on the forehead furrow phenomenon: when I first got the helmet I got the hotspot after half an hour, just like in the pictures.
I'll admit, I thought about doing a little sculpting with my Sawzall, but what I ended up doing was taking my right thumb and pressing on the EPS under the liner at the appropriate spot. Worked like a charm. So far I've ridden for six hours and no hot spot.
That was easy.
