Onto part one of the teams --

Pros for them: Joe speaks fluent Mandarin Chinese. He also coaches youth sports which embody some good qualities for a racer (patience with others, will to win). Heidi lists traveling as a "hobby." Heidi also seems to be quite smart -- was voted "Most Likely to Succeed," "Most Likely to Win a Nobel Peace Prize," and class president in high school.
Cons for them: Heidi was also voted "Most Likely to Total Her Car." She says that Joe tends to be "intense, short-tempered, and thinks he's right all the time." Uh-oh. We've seen that before. I find that sort of racer hard to enjoy. Joe says Heidi can't multi-task. Huh? A mother who can't multi-task? Methinks Joe is wrong!

Pros for them: Jody may be over seventy, but this woman is in great shape! Triathlons are listed amongst her "hobbies." She's proud of the fact she decided to lead a healthy athletic life and leave her sedentary style behind. Shannon is young, listing running, dancing, and swimming as hobbies -- all hobbies which require some stamina. She also seems well-schooled.
Cons for them: Jody thinks she's a comedian. That doesn't always work so well. All she could think to list as a pet peeve for Shannon is that her clothes are sometimes too revealing. Shannon thinks Jody can get a bit carried away and uptight. I don't know. They look like a pretty solid team to me despite Jody's age. (Mind you, I have nothing against 71-year-olds -- they just don't tend to fare well on the show.)

Pros for them: Well, they're cowboys. If there's any horse-riding or bull-wrangling to be done, they're going to stomp the competition! On a serious note, they're both athletic, always a big help on the race.
Cons for them: Neither seem to be too well-traveled outside of the rodeo circuit, especially seem to be lacking foreign travel experience. Cord says Jet likes to voice his opinion (too much?). Jet says Cord isn't punctual. Both seem to think communication and decision-making might present problems. I wonder if they're going to wear their cowboy hats through the various countries.

Pros for them: They're (thankfully) not in the race to test their relationship or to work out problems one way or another. They seem to be a very solid couple with a good relationship. He seems to lean towards the athletic side while she's proud of her academic achievements. Both appear to be driven to succeed.
Cons for them: She says he burps. I so don't want to see a man burping all season. He better not! They don't seem to have any immediate big drawbacks. They might not be all that well-traveled in light of foreign countries and probably just speak English.

Pros for them: Brandy speaks Spanish. Both enjoy traveling and might even have some foreign travel behind them. They're both very confident women who want to prove a female team can win. Carol seems to be more the intellectual while Brandy is more athletic.
Cons for them: There might be a bit of conflict. Brandy thinks that Carol tends to be too rigidly structured at times. Carol says Brandy is a biter. Yikes! I can see her running up to other teams now, biting them so they'll screw up a challenge! I don't know. I'm not seeing any obvious flaws with the team, but as they say -- others are younger and might be faster.

Pros for them: Um. Well, they're young and healthy. They're both athletic. They're pretty people. Both have traveled a bit.
Cons for them: They seem a bit shallow. Both want to build their relationship. I don't know. Unless it turns out that their personalities are so intriguing that I want them to do well, I just don't care about this team. She got in there because she was dumb while pretty on national television.
Part two down the road, hopefully later today as I'm snowed in anyway!
