My main sponsor is
icoocash, my ratio are down for the summer and recuring is not crazy with them but they convert pretty well. If you want sick ass recuring go with
Adultbouncer. I had members for 6+ month. The average member value is 50$+ and the conversion is good. They are different from the usual sponsor and I love them. I started a niche website with other sponsors I will see how it goes.
