buying a helmet...

[DC_T]

thanks guys for the comments. after reading this: http://soloracer.com/helmettech.html i was pretty convinced that i should get a SA rated helmet. After a little more research, it looks like autocross allows M or SA. Which, in all honesty, thats probably what i'll be doing most of the time, so a M helmet would do. But, if I ever decide to get into road racing or do a HPDE, it looks like some clubs require SA approved. Anybody know anymore information about this?
