I've tried the shrink method in the past without problems (I think
you have read my own description of the needed steps).
In other cases, I just copied the files (you get a free defrag too).
I'd trust cp, "tar c|tar x", rsync (all with powerful
"copy everything" options), but I would be a little worried
about dump/restore (in any case I usually work on reiserfs,
so dump/restore is not an option).

Dump is considered a bad choice by Linus himself; read this:

(a few years ago, but the words are quite strong)

Best regards.
