Not to nit-pick, but I recall the EB team said Lorica Segementata was not used too much, well not quite as much as thought. I also remember that roman helmet you displayed, I thought they didn't use that too much either. Or I am making it all up, I am not sure.
One thing I am relatively sure of, I thought the Xyston was used as a two handed lance by cavalry, whilst the one used by hoplites was called a doru, and I am not sure if these measurements are correct, but they were about 7-10 feet in length.
That is all, but remember the rest is very informative, I like it :)
