I've been running both (randomly) for a while as an experiment.

Number 1 is pretty and shows a lot of different models.

I prefer number 2 though, as it's a bit different to what people expect a porn site to look like. It's got a more amateur feel too, which means new members tend to be more impressed when they see how much is actually inside.

Can anyone think of a disadvantage in having both and letting affiliates choose which they want to promote?
