How should I setup ai candidates to do this...

[racinjoe013]

In CM, I want to create a candidate pull of 10 different car types with an option of 5 different skins for each car type so there is a 50 car pool. Then when I go into a race, depending on the field size, I want the game\CM to pick at random from that list of 50 so that I get a variety and different cars and skins each race.

To achieve this, do I want to use Random or Shuffle for the 'Arrange Way' option? Guess I'm confused as to what the difference is between Shuffle and Random. Seems like they would do the same thing.
