Vest!
All that stuff literally rides lighter in a vest than 24 oz of water in a three-bottle waist belt. My first one is/was a Nathan Intensity, which I wore out but got Irulan to refurbish (she does great work BTW) - now I also have an Ultimate Direction Jenny. No bounce, very little slosh in either one; they fit a bit different, but both hug the ribcage and stay put. It does obviously change the balance of my upper body and I have to work harder not to lean forward at the waist, but I'm too far out in the country to run long without bringing water.
For bare essentials on runs too short to carry water, and also for gels while racing, I have a Nathan Gel Pak. The pouch part is well structured without being stiff, the belt part has just a tiny bit of stretch, so it sits snug and flat on the small of my back without any bounce at all. I tried like five different belts before I found that one.
