'can't speak for him, of course, but foggy' has reported fills in some of the high end Petersons so has sworn off them. If I recall, he used to have quite a few, now mostly Dunhills, and only specific series in those.
I have a number of what I think of as mid-grade Petes, and a few low-enders, and I have yet to spot a fill, so I've been lucky. Some of these are years old, so I think fills would have surfaced. They may have some, but they were done properly and don't show at all.
