The vendors area was pretty small. I went to the Arai tent to look a helmets. I told them i currently have an X12 Shoei that fits well and wanted to know what Arai would compare to it in features and fit. Well the head guy there looked at me like I'd just told him I have a raging case of herpes and head lice that just won't quit. He wanted $35 to do a "fitting".
I'll stick with Shoei or maybe give Bell a try.
Ask Bender, he nose stuff.
