remember Bill, we don't see jack chains on anything but jacks. meaning low man on the totem pole as far as plate. i don't think they would work so well on an arming doublet with a bunch of other armour. If she's going for a "more plate" approach, I'd skip the jack chains.
Yeah, I admit to having mixed feelings about the jack chains... I think if I were suggesting it to be normal, then it'd be out of the question. I don't think it's entirely unplausible, though, and that's why I think Pamela could get away with it for the time being until she eventually upgraded. But your point is definately well taken.
(And FYI, in case I've never said this before, you and your guys have some FANTASTIC kit!)
