Raven at Foxy Ladies
I would agree that the majority of SPs in the Hat are a waste of time and potentially money. The only one that was worthwhile and quite worthwhile at that was Raven at Foxy Ladies. Not sure if either she is still there or for that matter the agency, but if she is she's definitely worth a shot. Raven used to work in YYC at Dunes, that in itself dates it, and was superb. Tall, longish dark hair and a great attitude.
I saw her a couple of times when traveling through her new home and it remained fun. Last time though was about 18 months ago.
If you do hook up with her, let me know - she's worth a trip in itself.
