I wear mine. Feel naked without it. All the statistics in the world are great, but no two situations are the same (is your head turned when you get hit? Did you flinch? Did you get hit with debris? etc). Stats are are often compiled from controlled tests in "ideal conditions" which is an engineers favorite because they simplify things. No such thing as ideal in the real world.
