If both sides ar playing to win:Reading the quest book and figuring out which quest is the correct one for you classes/group size/skills is a huge part of winning as the heroes.
If you are playing for fun and don't mind if the OL kills the heroes sometimes:
Random is fine.
This is why I believe that the most experienced player, who has read the quest book, should play on the hero side. He can suggest the correct quest without giving away the story to new players.
