Haven't tried a load bearing belt. Like the modularity of using several smaller bags and just toting what I think I would need. Unfortunately, there is no such thing as the perfect camera bag, for my carry the camera, two lenses, and a flash, together bag I use one of the Crumpler multi-million bags in what they call snot green. It draws attention but for some reason doesn't stand out like a camera bag.

You are right about the camera gear standing out, but sometimes it can be a good thing and you can use it to your advantage.
