despite the fact that many guys on here say all AW feedback is bollox, i think sometimes it can give you some useful information. For example, someone has today left her a "timewaster" feedback. If you look at his feedback, it suggests that he is a genuine punter and i would be more likely to trust his review than certain other ones. Also if you look further back on her feedback, a punter has used another name (not hers) so maybe the profile has been "sold on" and therefore the good reviews maybe for a different lady.
Although i know nothing about her, and Bristol is not my area, I think you are right to use caution with her.
