Well rather then explaining to me where your 38.1 sled data was you blew me off. So as much as I like your product philosophy, untill I am sure it wont be a waste of money I cannot invest in it when SCCA decides to require SFI 38.1 devices. This does not mean I will go out and buy a HANS, there are competition I am looking into, and will chose when I feel I have read what I need.
