I am looking at a new helmet. My Shoei RF1100 is 6 years old and my last time at the track they let it slide but said it would not pass again. I love the RF1100 and Shoei in general. The GT-Air is a nice helmet but I just worry about the internal smoked visor. Seems in a big craxh that might be an issue and it's not SNell approved. Not a big deal on the street maybe but on the track I want all the protection I can get. Anyway are there any thoughts on these 2 helmets or helmets in general?
