I would go for the experienced surfer.. they have all seen the crappy free stuff over and over again so they might be tempted more to give a few $$ for quality porn while new surfers are looking for that mass amount of free porn on the internet they've heard their friends talk about...
On the other hand, a new surfer can be tricked into getting out his CC much easier than experienced surfers who just overlook the ads..
So frankly, I have no clue
