So, I know that FX armor can't make Centurion. But I'm not sure why. I understand that it's not accurate enough, but I'm wondering, what it is about the armor that is so inaccurate? The general measurements? The details on the Ab plate? The way the pieces fit together? I have some FX, but I'm making it into a Sandy with basic approval as my goal. But as I do this, I'm trying to make it as well as I can.    So what about the FX is so bad that it isn't acceptable for Centurion?
