Any suggestions? Here are a few I've had my eye on. Any help is greatly appreciated.

Cammy has had some good reviews - http://orangecounty.backpage.com/TranssexualEscorts/super-sexy-ts-barbie-and-these-are-my-actual-photos-come-see-why-im-so-addicting-22/12594124

Daisy -  No info, sorry.
Lina - probably traveling with Nelly but those pics are fake.  A so so provider.

From your links....my opinion is as follows:
Top choice is Nelly. Pics are spot on, smoking hot, and if a newbie you will leave going what the fuck just happened, how can that hot thing have a tool.  

Second choice is Cammy.  I saw her pre-boob job and had fun but I hear she is a bit flakey now and not as accomodating as she was in the past. I could be all wrong. Regardless, she is also smoking hot..pics are accurate.

Nelly has been in porn...she had a preview vid on shemalepornstar.com but not sure its there now.  The only thing I do not like (and its pretty critical) is she wears these striped leggings or stockings in most pics and her vids.. reminds me of Dr. Seuss....not my idea of sexy but she must like them.

Good luck.

P.S.

Scroll about half way down and you will see "Nelly".  Its a preview vid.

Id go with Nelly, ive seen her posting on BP in LA before and shes just fuckin hot.  If you do let me know how it goes, ive been wanting to experience her

The link you posted for "Nelly" in the OC and this link for "Nelly" in San Diego:

Would appear to be the same girl.  However the link that LaTSdog posts for the video preview would appear to be a totally different girl.  Which one is the one that is getting the rave reviews?
