I use an old outdrive, 600 sandpaper, and do several figure 8's to get a crosshatch on the rings for traction.
I've never mic'd the rings but actually had that thought tonight.
I got a 4x4 piece of marble. It has a really flat surface and place the paper on it. Use motor spray to lube the paper. Makes it nice and flat. No need to but the expensive aftermarket rings that are way overpriced.
