Based entirely on Bios:

Love (and this is Love in the sense of slightly positive towards them, these people are no Goths, Hen/Az, or Ron/Christina)
1. Aja & Ty (Required rooting)
2. Tony & Dallas
3. Terence and Sarah
4. Nick & Starr

Middle of the road:
5. Anita & Arthur
6. Kelly & Christy
7. Mark & Bill (Something about them screams "FAKE AND OVERBEARING" but who knows I might be wrong)

Worried that I'm going to hate
8. Andrew & Dan (Team SUPERBAD is just telling right there. At least they didn't pick mactor alpha male frats but still...)
9. Ken & Tina (He screams dumbass and she screams controlling bitch, sounds like... fun )
10. Anthony & Stephanie (Nothing is said of their personalities by the other racer, I think we have our new Nate and Jen)
