Copy from r.b.t;
> So how do we know which to use? Is there a method of measurement or design
> criteria that determines which to use?
Top-swing should fit all applications that work with a seat-tube clamp. If there's
clearance on the seat-tube above the large chainring for the clamp, then bottom-swing
should work as well. Bottom-swing has fit all of my bikes.

The bottom swing is the old style high clamp front derailleur. Many full suspension bikes need this style due to the lack of a clamp area as low as the top swing (low clamp) style needs. As far as I know, there is no performance difference except the recent (but not '03) XTR which is a version which the inner and outer plates of the cage move independently. My Jekyll, for example, needs a bottom swing front derailleur.
