For your exits or 404's, use something a little different:
Dating sites work VERY well, and
Liondollars have over 10 to choose from with geotargeted ads and a bunch of other tools.
Celebrity sites also work well, converting all types of traffic, and you cannot go past
RevshareRewards
For your 404 and exit traffic, go no further than
ReviewCash which offers multiple straight and gay hand rendered domains with hand done reviews matched to your traffic - with or without exit chains of their or your own choosing !!!
A nice mix sees you bank !!
