If this is the provder you're talking about, then I've seen her a few times when she used to go by the name of Li.  She used to work with a crew who worked out of Sandy Springs and advertise on Surpreme.  Even though these girls try to get you in and out very quickly, Li always went out of her way to make our experience special and I would ignore a lot of the bs.  I found her to be very good (I think it was her vollyball background and her stamina) but she has/is known to be very YMMV.  She is tall, sweet and sexy.  I would recommend--though I have not seen her in about a year.  Let us know if you see her!
