I just got a set of minoura rollers a couple days ago. It was a little strange at first, but I got the hang of them after a couple minutes. Looking straight ahead definitely helps a lot. When I look down at the rollers I start moving all over the place. Also, I found it much easier to ride them while clipped in.. I had a hard time keeping my spin smooth while not wearing clipless shoes.

Also, I think if I had done it again, I'd have gone with 3" kreitlers. The minouras don't offer too much resistance without the mag unit (mine came without it), and it's actually pretty bumpy and loud. I hope all that vibration and whirring doesn't tranfer through the floor to the neighbors below me..
