My take on the OPs selection:
Hot & Horny - was on my HL for 6 months+ and no increase in FB. SUggests she's retired. Shame as she's hot bodded. Love the pics of her on the beach at night
Carmen Elite - on AW for 18 months, feedback of 9, three from same punter in a 2 week period. I'd call that suspicious.
Rhona - EMailed for a date, didnt have courtesy of a reply, so history AFAIC
Phoebe - Bum fun not listed. Plus I'd rate on looks 4.5 to 5 max.
Jury is out on:
Veronica Wet - For the price, tempted as she's a non-smoker, and for an hour, I'd risk the cash.
Diamond - Vicki has left me dry every time I've seen her. And no issue with anal. Always seems to be service oriented.
