From what i heard about these areas, the women in them are models so they don't last long as they go to the higher paying next job, or out on their own so don't be shocked the turn over is high add to that as a model gains popularity her price goes up and many can't afford high end models, as far as the companies go, to pay these models naturally they need a great bank roll, or great sales, and since the majority of vid producers pretty much have a rubber stamp writing and scenario and production to it, after a while it drowns out and sales level off, when Napali Vids came out it was the hottest gammon town, a mix of Sex fight, breast fight and timid cat, but what he got away with was the looped editing , at first everyone thought they bought a full one hour video, but as people watched closer the videos were only actually like 35 minutes , he just shot the video from several angles then in editing he looped one scene 3 -4 ways so you paid for an hour long vid but only got 30 minutes, this allowed him to pay a model an hour maybe two at for example 300 an hour, upon sales he made couple thousand but there again other than Joi, Mikki, and Danni most of his models moved on and now he takes his old stuff re edits in digital for DVD and barely has a new line , why he nearly dropped out of sight.
