If you want to get low level to your subjects than a skimmer pod (or homemade job) is the way to go. Something I noticed lastnight when trying to move the gitzo flattened out is that the legs were brushing against reeds and making a lot of noise. The skimmer pod is like a frying pan (but only ways 18oz - ideal for travelling overseas with weight restrictions) and has a standard thread (3/8"?) for a Wimberley, Ball or QR Clamp. With that you can slide through mud, sand, dirt etc. I'll take a read of it later, but that's my first impression.
