ok am having an issue i'm on the heavier side and i need to know what to do with the thigh armor. i know to keep the front as accurate as possible but it leaves a large gap i will have to shim in back. however the shin armor fits perfect any ideas on what would be allowable for the back of the thighs gap is like 4.5in to 6in at the top and 1.5in to 3in on the bottom ridge to ridge
