I'll add to this: It would seriously behoove you to take an entire afternoon and camp out at Iron Pony. I know it's a 2 hour drive for you, but you get to try on EVERY type of helmet out there. The nuances are numerous, it seems like most every manufacturer uses a different type of head form to make the liners, some fit round heads better, oval heads, so on. I'd personally take the drive and the lunch with some of us over sending the helmet back. There might even be a good closeout special when you're there, but I would still check internet pricing. Picked up a Scorp EXO-700 for 160 when they were on sportbiketrackgear for 110.
