Carolly: the neck is going to be covered by the yodare. As to the armpit -- yup, that's the weakest point in most yoroi . Of course, after the Genpi wars the back was far more open, too, since by then the code of bushido demanded that back armour was irrelevant except to a coward. Of course, that didn't mean everyone (not even all Samurai) ran around with no back plate of any sort, It was more of those stupid ideals that a society claims to live up to but knows are impractical, like the way the west believed sex to be evil for the longest time. Thank the Goddess we're over that. Huh? What? whisper whisper Oh, okay. Sorry. It appears that sex is still evil and bad and gives you diseases and sends you to Hell, which was what I was indicating above, of course, but my assistant pointed out that I may have phrased it badly. Don't do drugs, either. Burn the aspirin.
