To be honest, I too prefer the Lorica Hamata. The only reason why Ive brought up the possible dates when the Segmentata was used is just for educational purposes, and to clear up any misconceptions as far as the dating is concerned. As far as I know, M. C. Bishop is a well respected historian, and a reliable source. But, with all that aside, even if you agree that the Segmentata would have plausibly been used as early as 10 BC, thats only the last 24 years of a 286 year long game. And as a few people have already pointed out, it is a rare thing to still be playing the game at that point. So spending the time and effort on the Segmentata would be a waste.....unless its made specifically for multiplayer.
