It's the choice you have to make. To what extent do you want two escorts concentrating on you (massge, oral, sex, etc.), and how much do you want to watch them interacting in a lesbian show? Knowing that, you can pick your duo better, although as with all punts, what they advertise is not always what you get. So, as it's going to be more money than a "normal" MF punt, doing your research is more important than ever. Good if you have seen one, or even both, beforehand for a solo punt, so have an idea as to their reliability.
Remembering my duos (probably about 4-5), I would suggest that my level of overall satisfaction and VFM were lower than for solo punts, but the good ones were very good indeed and highly memorable.
