The answer (like so much with Jack and Ardour!) is that either will work.
I like to create a new track for the effected take, and route the
output of the old track to my effects chain then into the new track.
I have a patch bay to connect my Delta 1010 (8x8 to the patch bay), mixer 
(4x4 to the patch bay) and a half-dozen or so racked effects units.  
(Side note - this went from being a right pain in the arse to brilliance 
once I understood patch bays and how to use a normalized path.)

I was curious about this myself so I ran a little experiment, by zooming
in to a gnat's hair and trying to see how far back the effected track was
after going through a compressor and a reverb.  The unscientific answer
was that I couldn't see or hear any latency at all.
