I dunno, imo the third one looks too thick. If you're looking for the ultimate head protection, you may as well buy a Bsuit. Then again, it could look completely different (and mostly for the better) with texturing. #2 solves nothing as the head is still exposed.
@Undeference: about that camo thing... aren't you describing an unhelmeted human player? They have a headband, and no protection.
