Hmmm...
I'm not sure if HANS (or similar) would have prevented the whiplash (which was lateral) in this particular crash.
HANS and other similar devices are really for head-on impacts, like this;
I truly believe that a seat with wings around the helmet (like I have in both 911s) would have helped though,
so perhaps upgrading your seat should be considered too.
Regarding specific devices, as you know I have the HANS branded device, and I use it on all tracks.
Mine has the sliding tether, which allows me to turn my head from side to side. I don't find the quick releases useful.
These considerations, plus brand and style are a matter of preference. All forms of club and pro racing require some
sort of device that is SFI-38 or FIA certified. I do not find it to be at all restrictive, and that took only an event or
two for me to get used to it. It's completely transparent to my driving.
To me it's just another piece of equipment, and certainly not the most difficult to use, but one of the more expensive.
If you do get one, the specific brand and features will be a personal choice, and I understand you are trying to build
up a knowledge base to make that choice. If you decide to get one, I do recommend that you make sure it has the
proper certifications for PCA, POC or other racing organizations that you might possibly go racing with in the future.
And of course, you can try mine out at Chuckwalla (either use my helmet - I have two set up for HANS), or have yours
modified with the hardware anchors.
