Iiiiinteresting. With using a bunch of helmets from the Dark Age Warriors box, I've managed to come up with a mass of what I think make for passable Andalusian infantry. I'm hoping the GB cavalry will be able to be used the same way too.
Also:
I'd emailed GB a few months ago about something or other, but they had mentioned they were going to both a light and heavy cavalry box. I don't know any more than that, but I suppose with two boxes there'll be quite a bit of variety so that we can put them to the various uses we'd like.
