satinchristy - best bet is to get 5-10 out there for the WMs to use - as GG said - I would concentrate on just using text to sell the sites - with regular banners mixed in - although I always try to make sure the banners are sized a little different than "standard" sizes to avoid the banner subtracting software and to jog the surfers eyes a little
then watch and see the conversions coming in from the WMs that use them - should give you an idea of which approach sells better. Then you can go further with more "template" pages to fine tune the sales.
