I would choose one of my very good friends who has travelled all over the world. With him being to australia, africa, the states, many countries in europe, south america all before he's even 26. He also can speak 4 languages: Italian, spanish, french, english
I've went backpacking through Europe last year and i speak 2 languages. (english & greek and a tad french) I think we'd make a great team. Too bad canadians can't join TAR though. It'd be soooo much fun.
