These girls were the ones I first started seeing some time ago - circa 2007
They were very much hit and miss. One of the best girls I've ever seen (Kimberley), and the one most responsible for getting me addicted, worked for them for a while before packing it it. However, by some distance the worst punt I've ever had was from the same group. Kirsty (I think her name was) was akin to f**king a damp sack of potatoes, and had a personality that'd make Hitler seem chipper and ebullient. She was a pretty girl, very petit, but a miserable cow.
I saw a couple more that were plain average, and given the prices they ask (£150-per-hour) I haven't been back for years. I can't comment on things now, but they've never struck me as a 'bait 'n' switch' outfit, as most of the girls I did see resembled the photos.
