do the little balls (as you call them) move. if they do, they could be copepods and they are good. Not too sure about them being featherdusters, do they have little feathery tops? How big are they? (.) or bigger?

Are the swirl shaped? I have a bunch of these growing in my tank and they appear to be small feather dusters. I read that they stay relatively small (this type of FD). I scraped off the ones on the front of the glass and the sides but leave em on the back. I use a sponge back there to clean and it doesn't remove them most of the time if I am gentle.
