Well, I guess I should start off answering my own question for the SPs I've met at Smart and maybe others can help me with info about the others I haven't met yet. I'm only a part-time resident of the Richmond area, so I don't get to visit the spa that often, but I've had great experiences whenever I have. Here's a summary:
Judy - I know... she isn't there anymore, but I miss her. He soft skin, her beautiful young-ish body, her sensuality, her desire to make you feel good all ranked very high in my experience. Her massage techniques were probably average, but when she undressed and climbed on the table with you, a heaven-on-earth was ahead. I've tried to contact her at SL, but she only wants to serve FS and I am not interested in that, so I don't know if she'll want to see me again.
Jennifer - I ran into Jennifer downstairs when I last met with Judy a couple of months ago. She has a very perky, energetic, athletic body and attitude that I find very attractive. She works out every day and the results show well. Her body is slim with long legs and very nice breasts. She is friendly and really seems to enjoy giving you enjoyment. While you're still face down, she undresses completely and then climbs on the table at your feet and uses both her hands and her feet to pleasure you at the same time in a way that I'll just leave it to you to experience to understand (of course, YMMV, but treat her well and she'll treat you well). Then you flip over and she's still on the table and it just gets better from there (still only HJ though).
Yoyo - She is younger and it shows. Unlike my experiences with Jennifer, Yoyo seems to be just "doing a job". She is polite and will undress during the 2nd part of the session, but she just doesn't have the same massage skills or sensual experience that Jennifer does or Judy did. I don't think I'll return for future sessions with her.
However, that leaves several others like Lulu, Lisa, Rebecca, Mary, Lucy, Cici and maybe others there. I hope some of you will share your experiences with these and that my reviews are useful to you, too.
