<Some of the Hans alternatives look pretty scarey . The Hans restrains on a
horizontal plane at the CG of the drivers head . The others I saw , maybe to
get around the Hans patent , have straps that anchor at a lower point so
foreward on the head presses down on the neck .

Has anyone looked at the Isaac device. It appears that it hooks to the
shoulder straps, has cylinder dampeners that allow head movement, but
restricts on quick movement. http://www.isaacdirect.com/ Take a look and
tell me what do you think?
