Yep! I use cornies almost exclusively for clearing. In fact, in most cases the ale goes from fermenter to cornie in the aging chest to kegger. I'm planning on putting my Schwarzbier into a cornie for lagering in the back of the kegger. (I think I can squeeze it in).
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
