I'm not too worried about a heavy helmet, as my HJC is pretty heavy. I also have a fat neck to support it.
Will look into the Scorpion. My only previous requirement for a helmet was one that would be comfortable with my glasses.
I used to think that too...until I got a lightweight racing helmet. I still wear my Shark modular 99% of the time but I have to say, for comfort my Shark RSR2 is pretty neat in terms of weighing nothing compared to the Evoline. The function of the Evoline wins me over though.
