I think it depends what you are looking for.   I follow the Dallas girls on a regular basis.  If you want a blonde, try Tiffiny of tvi girls as she always gets good reviews.  Great brunette at the same place, try Holly, somewhat hard to schedule but you won't be sorry based on her reviews.  Might also check a couple of independents,  either sara of texas, or caseyof dallas.com  I've seen her, she is the real deal.  If you want young and beautiful, try Laylonie.  She's the only one with a limited number of reviews that consistently rate her a 10 in looks.  Her performance is excellent also.
If you want asian, try Yumi, Bebe.  Hope this helps.
