Array loading Random MovieClips

So…I have a main Movie and on certain frames I need to play a random MovieClip which contains a quiz/question…drag/drop…multiple choice…or whatever…so…I’m wondering out of the many ways my mind wants to do this…which would be the smartest.

  1. Put all those MovieClips into a main Movie…and have the Array jumble up the frame number to jump to…when it’s been used…take that frame number out of the pool…

  2. Have just the Actionscript on that frame when you land on it in the Timeline…have the Array jumble up the external movies…and then pick one and load it on that frame…and then remove that choice out of the pool…

If anybody can think of anymore ways…please feel free to throw it out there…thanks…
