Brad, since my favorite wash media in general is "The Bone", which is a microfiber covered sponge (it's a special "non-split" microfiber that's supposed to release the dirt), I also use that for rinseless. It does hold a bit too much water, which is why I mentioned that I have a bunch of Meg's QD Sponges that I got at Big Lots when they stopped making them (in 2004, I think), that are similar but have a less dense sponge inside, which over time breaks down to leave more of a flat sponge, if you will.
Some guys use the MF mitts which are a similar microfiber material. I have several but I'm not sure I've actually used any of them. I will also use Muppet Head (microfiber chenille) wash sponges, they used to have microfiber terry on the back, but now they usually have a scrubber which is not so good, although I see Sonax is selling one with terry on the back. Then of course there is a "madness" microfiber wash material this is supposed to be the best of all worlds, but it's very expensive.
Over at MFT they have all this stuff, their version of the "madness" (bright green) in a mitt and sponge, as well as a mitt and pad with the "Bone" material on it. The pad is huge and feels rather stiff, I just bought a couple but haven't used them yet.
