I've not seen either of the Playmates girls so can't help there, sorry.
I haven't seen Candii either...but I completely know what you mean, there is something that has been holding me back and I can't quite put my finger on it. It might be the obviously false tits, it might be the fact she is very much the top end of the price range for Leeds (not counting Lexxi Rocks haha), it might be the fact that she has almost 1000 feedbacks on AW. I just don't know.
I've read excellent reports on here here and elsewhere, and I have had personal recommendations from a couple of guys on here who's opinions and judgements I respect and trust, but as yet I haven't booked her.
Maybe a Christmas present to myself is in order...
