I know this is off the main topic. But the OP asked about UTR girls and this info helps fill out the picture for him, I think.
Advantages:
Scheduling flexibility - whatever day and/or time you and she feels will work. Up to and including the occasional trip together. Don’t forget about YMMV though.
Menu flexibility - She’s not worried about reviews anymore. Contrary to what some people might tell you, this is almost always awesome. She is far more likely to be willing to try something she may have never even tried before. Remember, she invited you to go UTR with her. There’s a sense of both camaraderie and trust which goes beyond what you had when you were just one of her customers. But remember: if you abuse that trust, her blacklist lasts forever. A great big YMMV here.
Disadvantages:
Scheduling flexibility - Yeah, this cuts both ways. Responses come directly from her. So, you may have to wait a while before she responds. And she’s just one girl. With all that entails. IME though, most girls who go UTR are pretty professional about scheduling. So delays aren’t usually too bad. YMMV, as always.
Uncertainty: She’s not an org. She does business when she feels like doing business. She may close up shop whenever the mood strikes. Whether she keeps your contact info after that is totally up to her. So, you just have to live in the moment with UTR girls.
Now, back to the main topic. One of the items was about predictions for the future of the biz.
I think that occurrence of independents and UTR girls will begin to increase as prices start to even out across the country and girls increasingly start thinking about how much of their money and independence (and k-girls can be very independent as we all know) goes to or yields to the org.
