Does any one know the high pay Pop-Unders network?

Does any one know the high pay Pop-Unders network?
I currently use paypopup and look for another Pop-Unders network.

My highest is tribalfusion, then valueclickmedia & casale media (about tied), then Burst!Media.

VC refused me, because copyright issues ValueClick
Media is not accepting anime sites.
tribalfusion, I'm not reach their traffic requirement.
Casale media doesn't respond me.

They are the standard high paying pop up networks.

Realtech and AdPepper might also be an idea to apply to.

Others offer pops though, maybe try the Yield Manager networks such as Right Media, CPX Interactive, Rydium, Joetec.
