I've had several large hits without a H&N device. Might have been a little soar after, but nothing major. In my closed top car, I will not use a Hans. The window net must fall down (when the car is right side up) and I believe the Hans could cause me issues getting out of the car if if were not right side up! (See Joey hand video and read the interview - linked a billion times on most race sites)

That is why (if I keep racing) I wont be using a Hans. The defender looks better, bit the risk of the belts hanging up is a concern as well. I know there are devices that use webbing tied to the body and those devices do not interest me.

I'm still for allowing folks who feel they are needed to use one but would prefer to not be required to use one.
