I really think that this alliance was serendipitous. The stars were in alignment for those teams, at that time, at that place. I don't think it will be repeated because these teams won't be there. Some teams in the future (fingers crossed) may -try- to repeat it but then one team will take a wrong turn and get lost for six hours, or one teammate will break down at a task and won't be able to finish (Mika, Jen, Flo), or a team will decide to break away (Karlyn & Lyn), or the tasks won't lend themselves to 'sharing' (swimming, diving, dancing, needle in a haystack etc.) I think this was a pretty unique set of circumstances that will be hard to replicate rather than becoming common.
