Most Holy Trinity Seminary in Reading, PA and St. Peter Martyr Seminary in Verrua Savoia, Italy are both excellent.
I do have the impression that those would be excellent seminaries at which to study. I would need to study the material-formal thesis more though and see if it was something I would accept, for it must be held in order to enter those seminaries from what I understand.
I wonder how the CMRI seminary is.
I do very much sympathize with the sedevacantist position now, although I am not one, at least at this point.
They training seems more impressive at the sedevacantist and Resistance seminaries more than the SSPX and indult seminaries, of course.
Almost two years ago, I was able to see on a retreat the former location of St. Thomas Aquinas SSPX Seminary in Winona, Minnesota, now Holy Angels Novitiate for the SSPX Brothers. It was wonderful to see where Bishop Williamson used to teach. Even more so, it was great to an old Dominican monastery there.
If I was a priest, I do not think they would put for too long or at all doing travel for chapels and missions, but I would probably instead be more of a professor at a seminary.
