Back in 09, PSD teams in Iraq were converting from high-profile, upper body molle vests/racks capable of holding a minimum of 10 mags....to low-profile gear. The high-pro gear was too threatening and offended the Iraqi's (good going Obama). You had to wear everything you needed on a belt and throw a big overshirt on to conceal it as best you could. I used a lot of belts and there was a major issue of the tops of the molle belts curling down due to the weight of the ammo/mags/pouches/holster. I went through a few before finding what worked.
The best one I found was the VTAC Brokos belt. It has stiffeners built into the padded belt to prevent the curling. I considered my molle rows vital for ammo pouches and did not want to waste rows attaching my suspenders. The VTAC has attached suspender attachment points which is great. Some belts don't. I carries 4 M-4 mags, 4 Glock mags, pistol holster, radio pouch, med kit all on my belt. Every molle column was used.....if the suspender attachments weren't there, I would have lost 4 columns (front and back) which is space for 2 M-4 mags.
This was nearly 10 years ago but I don't know if it could get much better than that setup.
VTAC Brokos belt
Inner belt with cobra buckle
Blue Force Gear suspenders
Blue Forge Gear rifle/pistol/med pouch
Diamondback Tactical radio pouch
Now if you're looking to get into the prone for PRS stuff, you'd have to lose the stuff on the front of the belt.
Med kit not attached in picture but you see the spot for it. I had 1 unused column and had a tourniquet attached via rubber bands.
Hope this helps.
