Another happy AT armor customer. What will you be doing while wearing the plates? Is this for a low vis rig in a high risk area or for a class rig/civil unrest rig? Your choice of a JPC seems to be towards the overt. If you are going "loud" , I'd look towards the 3810 as the slight reduction in thickness provided by the U210 (which makes it easier to hide, among other things) is offset by the fact that you have it in a visible military style carrier.
