I'm really surprised no one has considered the Zapatera Tribe (Survivor Redemption Island) for this list, especially as the Ometepe got the Five Bad Band honors.
I've got two candidates for The Big Guy (Steve and Mike) and The Lancer (Steve and Julie); Sarita was called the Team Mom, making her the prime candidate for The Chick; if you ask me, David definitely qualifies as The Smart Guy and Ralph, by simple virtue of being shown to start it all, as The Leader.
