FWIW sv650man comes across as an obsessive type. Multiple bookings with the same escort in relatively quick succession and then he moves to someone else. I wouldn't tarnish the SP just because of that but it does raise an amber flag with me. However, one of her other feedbacks looks very genuine. That punter also has feedback from 2 reliable and very down to earth girls whom I've seen.
In terms of her profile, she or her boyfriend/pimp/management just come across as not very bright. Doesn't mean she isn't a good shag. Other than that, she's 5'9", thickset (read chubby) with a big ass and likely swallows. If I were visiting Bristol, it might be a bit risky for an hour punt but, if I lived there, I'd try the £50/15 min option to see if she's worth a longer investment.
Also, if you want English and she ain't, then walk.
