Nothing wrong with VBR, but you need to take care when munging it once
more.
Vorbis codes completely differently than mp3 and has far less audible
artefacts, in general. It's also easier to "tune" Votbis to avoid its own
artefacts, ime.

It all depends, as always :-) The music content will also dictate the
choice. And it might be appropriate to use different encoders for
different musical styles.
I guess it seems like a lot of work to some folk, but a 12 hour flight is
the wrong time to discover that your chosen type of music sounds crap now
you are really listening to it.
Anyway, the OP is going to mp3, so he's screwed whatever he does, imo :-)
