Currently for BDUs i have a Tru Spec made BDU belt.
For the first line there has been normal Alice belt, with and without beltpad, TT molle belt and dozen other 'tacticool' belts. Suspenders doesn't work for me, because when i 'hug the ground' the belt ends up somewhere around my chest, completely the opposite, which is weird.
The idea in the picture in my opinion is great, and probably many people use those like you do. Only concern to me is the short torso that i have... oh well.
