Hi Steve:
I hope to see you at Spring Mountain.
I know where you are coming from on the head tilting forward analysis. That HANS video link above is not the best one though. When you buy a HANS you get a CD with it. THere is a lot of educational video. I could not find online the one I was looking for. On the CD there is a clip of a high G impact. IN that video, the head moves forward at the same horizontal plane as normal. It does not rotate down at all. The body moves forward until the harness slack is drawn tight and the head just keeps going forward. That rips your head loose. A collar won't help that and when you watch the video I could see how it could just add to the leverage.
Hence, that is why I challenge people at both car and kart tracks to show me a study that shows a collar helps tangibly. So far no one has produced any....
