I don't think I'd say Vancouver SPs are just average looking. I think recently we have had SPs that were in Playboy, FHM and Maxim, Claire Frost and Bella Ferrari were two SPs that come to mind that advertised this and that should qualify them as being well well above average looking. There have been other recent SPs that were former strippers at Brandi's, cheerleaders and Cactus Club waitresses, and those jobs pretty much required them to be above average looking as a qualification, so I'd say there are lots of pretty SPs here locally.
I'm not sure about people exaggerating SP's looks to win favour, it could just as easily be said that the people that call SPs 6 or 7s instead of 8s or 9s are trying to be elitist. I don't know how you can call someone a 6 if you've never met a 10. But then again everyone has a different curve and different tastes. For example, I think Jennifer Lawrence is pretty and I'd definitely have sex with her, especially if she was wearing her Mystique outfit, but I wouldn't call her gorgeous or stunning like the media refers to her as, but that's my taste. She seems like she'd be pretty fun to hang out with though, would be a fun evening to trip over red carpet and watch Homeland DVDs with her...
With respect to Sasha Carmelle, I have never met her and likely never will, I filled out her form and everything and never got a response
