With the optional Undersling attachment, you can use your Ergorig to shoot underslung while still transferring all the weight to your hips, totally bypassing your spine. The Undersling uses a small strap to attach to the top handle of your camera, and you can then use the elastomer band to adjust your shooting height on the fly. If you need a little extra height, throw on the Undersling Riser, which has the built in benefit of acting as a quick release to unhook the camera from the shoulder plate. The band also has some serious elastic properties, so it will take steps out when you're moving, in a way that other systems won't.
