Two methods depending how fussy you are.
If you're not particularly fussy - ie don't have really specific requirements - then just go to the UKP review section for your region, read all the positive reviews until you find one you like. Simples.
The longer version - start on AW, go to Search Members, create your search filters (sex, age, incall/outcall, likes/dislikes (ie exclude barebackers, include FK, OWO whatever is your thing), personally I mostly search those with pictures and with viewable ratings but up to you.
I also then go to the proximity tab and put in my postcode and select a distance (for me 10 miles is normal but depends on your travel options).
I do also sometimes filter by height on the "Interview" tab - fortunately I prefer petite women so under 5'4" works for me. Unfortunately you can't specify custom heights so it's a blunt tool. Not much else on the Interview tab I find useful but YMMV.
Click search and that should find a bunch of girls that match (hopefully) - then you go through, check the pics to see if you like them, then copy their AW ID from their profile page into the UKP search window and see if anyone has reviewed them.
The AW ID is displayed at the bottom of their profile page:
"Link to this Profile Page using
External Link/Members Only2019595..."
or in the URL:
"
External Link/Members Only2019595"
It can be a time-consuming process which is why I now mainly just read the UKP reviews and add to my HL when I find someone who fits my taste.
