Agreed. I should have made it a little more clear my answer was half facetious. You have to balance safety and realism. Any time you train full head shots, you run the risk of concussive episodes - there isn't a helmet/head protector made that can prevent your brain from rattling around inside your skull. If you are only concerned about external/surface injuries, then take a look at full coverage helmets made by FIST, Redman w/cage, High Gear, etc...
