Face cage headgears are dumb anyway. If you like getting hit in the face with a big sheet of plexiglass more then you like getting hit with a fist, fine, I guess it's a coke-pepsi thing.
I think the cup is pretty much going to happen no matter what, and who's gonna check anyway? Besides, it keeps loose beef of your chin in the grapple. :P
I do think it should be stated that a third member or members ref the match - that has been the situation thusfar with most of the heavy TD sparring but only because of common sense, and that Knightmare is out there, and it doesn't have brains, or restraint, it just fucks up and fucks up and does . . . not. . . stop.
