Okay, this is all great info. Thanks guys
The helmet in the link above should be SA2000. It has the followig in the description:
Snell SA2000 - It's open-faced, but I'm slightly claustrophobic and don't like having my head completely surrounded by anything. I'll go to a bike shop first I guess and try some full helmets on and see if I can deal with it.
My guess is that would satisfy requirements, but I'll be certain to check all the rules and stuff beforehand.
Thanks again! Hopefully next time I can get some video clips to show off.
