From my experience it is purely up to you...What would you like to see? The only advice I would have is to run your fog throughout the night...maby less during your slow sets. Your fog will accent the beams of light and it is more effective when you have the faster tempo moving the lights like CrAzY!!! Gives off a since of excitement!!!
I like to use a strobe to mix up the beat a bit...just hit it temporarily during a bass hit or multiple snares. Just my preferance.
