I just received the plate armor I ordered for my vest. It was listed as having one curved plate and one flat(with the two smaller side plates). I opened the box, and both plates are curved. Is there any problems with having a curved plate on my spine? Will it cause me any discomfort? Should I contact the seller? The seller is taking off a week, so that will be a while before I get any feedback. What say you, INGO? Do I just go with it?
