My go-tos are Simona on Sint Annenstraat, Veronika on Stoofsteeg, and Desi, who is now in Singel on Spuistraat. Ella on Bethlemsteeg is also nice, and Agnieszka also gets very good reports, but I've never managed to see her.
The trouble is, most of us regulars on this site have our favorites already, and tend to stick to mostly seeing them, so not a ton of new girls get reported. We don't get a ton of new blood here, and when we do get new posters, a lot of them seem to post maybe a handful of times and disappear without contributing, so the girls section has stagnated somewhat. Nothing against this site, of course, it's a fantastic resource and the people here are great, it just is what it is.
What I do from time to time, and I've had good success with, is to use the hookers.nl map:
http://www.hookers.nl/maps/showmap.php?f=F9aIf you notice, quite a few of the girls there have pretty good ratings, and many are unknown/unreported here. I like to make a list of some of the girls on the map and try to find one or two of them. That's actually how I found Desi, back when she was in De Wallen. It's a bit of a risk, of course, but I've had some very good sessions that way.
