I think people are missing the point. The idea is to have a lowpro setup that is built on to full kit. Using a CH (outside of a tenspeed setup, which sucks to work out of) is not going to be more lowpro then this belt setup, you are welcome to prove me wrong with video using the same cover garment as the last vid.
The other issue with the CH is that it does enhance the addition of armor or maintain the same mechanics between EDC style lowpro and full kit.
The belt allows speed reloads on rifle and pistol from the same index as your EDC pistol carry and allows RWR to come from the PC front. The belt also allows reloads on the rifle from positions that make the front of the PC hard to do.
Working out of a grab bag, diaper bag, etc. is good for TV (ala Jack Bauer) but sucks in reality.
Obviously when you take out the carbine things are no longer lowpro, but picture the scenario where you are about town with the carbine in the vehicle. When fighting back to the vehicle (thus heavy on pistol mags) haul ass out of the area and transition to the rifle as your primary, you now have one mag in the gun (one on the stock pouch?) and a speed load ready on your belt. No donning anything, no working from a bag or pack.
This rig will conceal under a long oversized shirt. Obviously not be hidden completely, most can't hide their EDC without printing, let alone add a radio, 3mags, 1 ar mag, WML holstered gun, BOK. To put all that in separate pockets and still have only a large shirt for concealment is going to require bulging cargo pockets I'm thinking.
I've tried to EDC a BOK with my normal G17, extra mag, P6 light and there is no place for it in a standard set of jeans when you consider the wallet and phone, keys, knife are also looking to use the pockets. I don't put anything in the back pockets for obvious reasons.
APX, you point about the waist line being the first place "AWARE PEOPLE" look is very valid. Most are not aware. Those that are aware will think twice about messing with someone wearing that kit and presenting the correct posture, I know I would.
The main criteria driving me this direction is having a pistol heavy loadout and MOA that does not change between "enhanced EDC" carry and the addition of a PC. I have been searching for days and this is the only thing that remotely solves the problem.
I think most are content to go from EDC to full kit. I see the bulk of needing firepower in SHTF in the "middle" of those two, and the pistol being the primary weapon with the carbine near by but out of sight.
