Yeah, I agree on pretty much all points. However, I've got to say that the Cho's never really got anything from 'Bama.
I'm not sure what the deal was with the Cho's, but they were so paranoid about going the wrong direction that they never really seemed to get anywhere. That might be why they waited for what appeared to be over 10 minutes for 'Bama to finish the tank challenge. If they were that unsure of their own ability to navigate, having another team along may have been a psychological safty net, but they certainly didn't get any advantage out of it.
And the women, sitting in the car complaining, but still letting the Cho's do all the work...Yeah, they made the right decision to go it alone, but they should have either stopped complaining or made the break sooner. Though it did appear that one of them wanted to make the split sooner and the other wanted to stick with the Cho's, so maybe it wasn't as bad as it seemed.
As for who to win...The couple (Rob and Jennifer?) seem okay still too. I would be okay with either them or the models winning, but I agree with you that the 4 teams left don't leave much to cheer for. The "barbies" and 'Bama have always been very annoying (for different reasons), so I would prefer one of the other two teams.
To be fair, now that the Cho's are gone, I would say 'Bama is definitely next, but it is possible that the Cho's were holding them back as much as the other way around. Now that they have to depend on themselves, maybe they'll do okay???
