The idea of taking to your hub thru a FPA is a very good idea - and once he's there, any link for a niche he clicks on should take him thru at least one fpa (if not more) before he gets to any free stuff
As far as the money bar - it's not an option anymore on free sites - very few LLs will accept them - just put a link to your hub with "more free porn" text - takes the place of the money bar and allows you to filter the surfer by niche a lot better
added - I know most sponsors tell you to use a money bar to filter traffic - it's a holdover from a few years back - most of them don't submit to LLs anymore
