Hello everyone.
I've got a couple of ideas on this. I'm in the Army and I recently returned from Iraq.
For me for day to day use, I can do an awful lot with quite a bit of stuff fixed to a regular old pistol belt. I used a VERY good thigh holster from an outfit called High Speed Gear, Inc., a canteen, a knife pouch, gerber multitool, and a magazine pouch setup similar to the thigh holster. All the weight rode on my hips, which didn't bother me too much, but might not be good for some. I don't think the "Y" or "H" harness is much use unless you are carrying a butt pack. I could carry my ruck and everything was out of the way. I strongly dislike the LBV, you can't breathe too well in it, you sweat a lot, the strings and straps and flaps are always getting in my way, if you have to go prone with it on you end up laying on your spare magazines, it's really just a nuisance to me. I guess it all depends on what you plan to carry, too, but that's what worked for me.
