I agree with others here who think the OP ought to give the rest of us the benefit of his experience.
To address the point at issue, my personal preference is for regular prossies. My 'longest serving' prossie, whom I first saw when she was 20 years old, is now 25. Over the course of five years, she has retired five times. She comes back to the profession and I book her again.
I have three great girls whom I see in rotation. They never disappoint. With different, new girls, the chances of a bad punt are fairly high. So, for me, it's regs over novelty every time.
In particular, I want BDSM punts, which tends to limit the potential pool of girls to just a handful.
Anyway, it works for me. Each to his own.
