@Frank the link doesn't work bro.
And yeah, I understand there might be a fetish aspect of slapping, hair pulling, wedgies, etc. But damn it, I rarely come across a good old scrap with an exchange of blows. NO fake grunts, and fake hits.
Another thing about Crystal Films is that their girls were just plain RUTHLESS, but with no real grappling experience. Can you imagine how entertaining the fights would be today with the same rules but now you throw in fighters like Ariel X, Dia Zerva, Veve Lane, Dragon Lily, Hollie Dunway, etc. (maybe retired amateur MMA girls)
Man! If I had the funds and time, I would start a production company that did JUST THAT. Get girls around the same weight, make the girls sign a waiver, and let them go at it. Only thing I would do is tell them that "anything under the neck is fair game" and give em the option if they want to hit each other in the face.
