An old question I know but I actually put less work into researching than I used to.
The dickheads on Prossynet always accused me of not researching enough hence my disappointments.
They couldn't actually be more wrong. Prior to a trip to London I used to spend hours and hours trawling through agencies, indies, together with Capt 69 and auto-censored Fr's. My method was usually to first find girls I liked the look of and then see if they had any feedback on auto-censored or particularly Capt 69. I usually took little heed of any feedback on agency sites themselves. The problem with this was that girls I often liked the look of had no feedback. I then tried it the other way and looked at feedback first. This was often disappointing too as I frequently didn't like the look of the girls with the feedback.
Later I also started trawling through AW and posting reverse booking requests. This was more often than not even more frustrating. Often by the time my trip was due I was fed up of looking at girls on the net, and in the days before 'smartphones' and ubiquitous wi fi I often spent hours of my time when actually in London still trawling through sites in Internet cafes in an attempt to find something - not ideal I know!
However I'm now luckier in my old age and have barely done any research at all, as this time I have simply arranged an appointment with Nicoletta and one with Karolina who I haven't seen before, but is highly recommended in the good providers section by my good friend Jerry whose judgement I trust implicitly. In turn she was recommended to Jerry, just as Nicoletta was recommended to me (I wouldn't have picked up on her otherwise) and I recommended her to Jerry and others.
Proof that word of mouth works and is a damn site easier than spending hours trawling through websites.
Should either of these punts fall through or should I fancy another one I can always fall back on Anna's Angels whose girls have always satisfied me.
Easy really innit now I know how!
