I've played with belts set ups for a bit. I found 2 problems that I always encountered:
1) I'm always wearing a pistol & mags (and other 1st line gear) so a belt with the same stuff is a waste of time.
2) if I'm going to take valuable time to out something on, it will be my kit with armor, rifle mags, bigger IFAK, and a rifle.

I dont see see a use for a belt for the stuff I normally carry on a daily basis.
