We strictly had everyone on paper for a long time until we got some problem feeders, we switched them to aspen and we've seen a marked improvement. I think it has to do with feeling secure, with loose aspen they can burrow and mold it to whatever makes them content (my pastel makes the same exact burrow pattern every time).

On the other hand there are some that just don't seem to care, and I have a few that I've switched to aspen just for uniformity's sake even though they'd be happy with even sandpaper lol.
