Current tiers (with commentary):
Upper
1. Shawntel - I don't care if she's a funeral director. I think she looks hot as hell and seems normal-ish. The lack of boobage is a concern. Brad seems to gravitate toward the better endowed. I suppose you can have all sorts of goals for this show. Brad parlayed his indecisive shtick into another season of globetrotting and humping on ABC's dime, so who knows what the right move is. I'd opt for her if I wanted the best chance at staying together. She seems to pass all of the initial diagnostics. You'd probably have to date her for a while to unearth the daddy issues or whatever resides under the surface.
2. Emily - Lacking her tragic history, she's #1 easily, but that baggage is just too much to overcome. The strange veneers are kind of weird too. They must be sort of new because she still sort of plays with them with her tongue. I not only think she farts rainbows, but possibly poops fresh raspberries and pees champagne. If you want a mom, here's your girl. She'll be hung up on the dead driver forever, so there's really no point to this this exercise. I probably would have cut her loose early on. If she ends up as the next Bachelorette, my opinion of her will change greatly. Could be a rabid opportunist in disguise, but is putting on a nice show and is auditioning really well for a shot of her own.
Middle
3. Chantal - Quickly losing ground after her episode 6 fiasco with that Bedrock-chic number and her sudden inflation. Her mental state seems to be in a constant state of flux as well. Somehow convinced Brad that her prior mood swings were out of character, but she obviously cannot handle this show's worn out format and is showing some serious instability. Seems to be lining up some new jealous girlfriend shtick that will be amusing to watch. I don't find her nearly as hot as most of you do, but she has her moments. The mams are just "okay" given what's going on elsewhere. If Brad picks her, they will hit splitsville in mere weeks. No long term potential whatsoever.
4. Ashley H. - Not a fan, but kind of perky and looks good compared to the lower tier dreck. I actually liked the other Ashley more, but they were pretty similar and perhaps shared a brain. She's been kind of invisible lately which is never a good sign for your future prospects on the show. ABC gave up fooling the viewer long ago and just features front runners. Two hours just isn't enough time to feature all of these epic journeys. The dentist thing continues to bother me, more than even the funeral director thing with Shawntel. Dentists are nuts. All of them.
Lower
5. Britt - Probably 90 pounds on a cookie binge day. I can't even comment on her as she's had no camera time. I think she's the fallback blonde option and must resemble Brad's mom or something. I can't figure it out. Based on looks alone, I think we can shelve this one.
6. Michelle - Pretty sure anyone with an IMDB resume like hers is there because her agent set it up. Not sure how ABC explains that other than to admit this is basically The Hills. I get the same feeling with her that I got when "The Wrestler" was on the Bachelorette. I put her at about 90% shtick currently. The real tears were impressive, though. If that's even a hint of her true personality, I'm sure a restraining order was filed at some point. Decent performance overall, but the act is getting tired. Brad's even having a tough time pretending to like her at this point. I liked Jackie infinitely more than her, but for the sake of ratings, Michelle was too important to the show. That choice should end all doubt (if there was any) that the show is horribly rigged.
