I have a Scorpion EXO-400 and a EXO 1000. Great helmets but don't quite fit my long oval head, had to modify them a bit. The 1000 has a couple nice features like the drop down sunscreen and inflatable cheek pads. They are nice but not really worth the price or weight.
If I hadn't got it for a steal I would have gotten another 400 or maybe a 700.
I just recently picked up a half helmet, a HJC IS-2 so far I really like it.
