White chicks???? Don't do it man!
Just kidding; Dupond, 7 Star and Studio Wet (love that name), probably a few others, have ethnically challenged girls I believe. Can't say I've partaken of that variety in recent history, but maybe some of the more adventurous guys could shed some light (get it?) on the matter.
As far as the best AMPs - they're all good, depending on what you're looking for. I think you need to center your interest and search on the girls rather than the location. As I've mentioned here on a couple of occasions - read, read, read and read some more. There's a wealth of info if you're willing to take the time.
Good luck.
