Hey bro Jeff. To stop the shins from rotating just add velcro on the upper part of your boots and the shin armor. Hope it helps. Regarding your application to EIB and Centurion for ROTK, did you know that on the CRL for level 2 and Level 3 they require us to have the butt and joint connection on the biceps, forearms using coverstrips? Our armor currently have the overlapping connection which is only allowed for Level 1. Did you upgrade your handplates to have a small indent on the front? This is required fir Level 3.
