The advantage of Front Curtain Sync is that it reduces the lag time
from the moment you press the button, until the flash fires.
A common scenario, is to use a slow shutter speed to allow the
ambient light to light the background, while the flash illuminates
the main subject. If you are trying to capture a specific moment
(i.e. expression, look, event) front curtain sync is the way to go.

A local friend of mine and I were debating front curtain sync vs. rear.
I put forth the proposition that while I understand the advantages
of rear curtain sync in certain situations, I could not think of any
disadvantage to rear curtain sync and therefore have set rear
curtain sync as my cameras default.
Are there ever any disadvantages to rear curtain sync?
Is there any situation where you would rather use front curtain sync?.
