I think I agree with your selection. I have seen Nancy and really loved her vibe. I didn't try BBFS with her, because she wasn't ready on that particular day and time. Overall, she is my 3rd best choice.
I have seen YangYang as well and she goes by different names (Honey and Helen?). I also dared to go BBFS with her and absolutely fun!
I have seen Lily (Encino right now) and she is good too. She is really fun and gives a lot of attention and works hard to please.
According to my taste and liking, I rate Ivy (not on SA anymore at all) the BEST!!! She treats her customers like a KING! Too bad, she is with other agencies and now works only in the SF Bay Area.
I haven't tried Wa'ner at all. Not sure why she is in Valley Village most of the time. It would be better if she moves around and gives other hobbyists a good chance 🙂
Here is my top 5: Ivy, YangYang, Nancy, JuaJua, Lily and Cindy (currently in Thousand Oaks).
