Was a regular customer before my current punting hiatus. Tina runs a fine agency and is very helpful - feel free to tell her what you want.
Only downside is that she is a little lax with the photos - some of the sets on there are a good 8 years old at least (Alex, Tia) and her definition of 'fluent' english is somewhat more generous than mine.
There has been an unusual amount of churn on her books recently, with many of the established girls disappearing for various reasons, so I can't provide any firsthand info on any of the current crop except Alex, Tia and Alexa (in order - somewhat standoffish; bigger than her very dated photos; good fun and willing but lacking in the looks dept.)
However, when my finances improve I am likely to return - I've come to trust Tina's judgement, and she has guided me well in the past - recommending certain girls and saying she 'didn't think I would like' others.
