Great thread!! You guys probably know this, but all k bookers do verification differently. Even at the same agency, depending who you chat with, the requirements can be different. From first hand experience, I can say that HX rating does give you some leverage with k-bookers that are also on HX. I've setup appointments with k-bookers on HX, and they ask for no additional verification.
I've even had some k-booker reach out to me and promoted their services. The good part is that if you are looking for a particular k-girl, she is probably listed on with half a dozen k-bookers. With k-girls, TER account is important if you want to have an idea of who you will be seeing.
Rebranding of k-girls is a huge issue. I saw the hottest k-girl in LV that went by Yumi. I eventually found out she relocated to LA as Baby something…. So annoying.
Either way, best of luck and happy hunting!!
