I know a HANS type device is the best, just now sure how much my wife and daughter would hate it. Thinking about a helmet support from Necksgen. They come in various sizes and I think having one would be much better than not having one in case of a lawn dart. Any real world experience with these? FWIW, most of our time is duning in SxS's (not a rail going 120+) although I do bring the rail on some trips.
