Similar to Holophile... I run a TT MAV (2 piece) with the X-harness and 6 x TT single mag pouches (3 per side). I also mount 4 x TT double pistol mag pouches on the inner most rifle mag pouches (2 per side). On the sides of the MAV, I mount a TT knife pouch on each side (one with a surefire flashlight, the other with a folder) and a dump pouch. On the back of the X-harness, I use an SDS FLC hydration pouch (holds 50 oz - 10 more than advertised). This setup may sound front heavy, but even with the hydration pouch empty and all mags topped off, the weight shift is not real noticeable. It is very well balanced with water in the bladder. I have worn this setup during pistol and carbine classes wearing Level II body armor underneath and had good functionality and no discomfort. YMMV.
