the best thing you can use is terry cloth towels.
i wouldnt suggest micro-fiber as the fibers catch most of the polish and it doesnt touch the ball. really the only disadvantage there is that you will be wasting product.
also using the towel or the back of abralon produces the same results. the advantage of using a towel is that you can use your favorite polish and just keep wetting it for each polishing session and just adding a little bit of polish, thus using all of the polish up each time instead of wasting it. its what a good pro-shop does, uses one polish and one polish "rag" over and over again till it looks soaked or covered in polish.
