The reflectors have kind of become my go to thing, especially being Assault Brigade, ie grunt infantry. It's a nod to real world military units and give the "friendlies" a reminder not to shoot me in the back lol. The thermal dets were an idea I got from Tassone... they are 2 for 1.00 air freshners. Rip out that nasty jelly stuff, glue the halves together, paint/weather attach. You're right about dead space too. With the Legacy backplate design and my kidney plate there is a large gap there where the MOLLE vest is exposed. I needed to hide it.
