Most profitable Paid Traffic sources for CPA

There're a zillions CPA BH Methods in this forums, some works well, most are POS but whatever methods we are currently using, we can make them long term methods by adding real converting leads to the offer(s) to mix it up. Using BH revenues to pay for WH and legitimate everything.

So i am opening a thread to find out people's experience in what would be the best source of traffic to buy in order to achieve real CPA conversions. Besides PPC. Regardless of the cost of the Traffic (not infomercial ;-) ). Best converting traffic money can buy. For all types of CPA offers : Email/Zips, 1st page submits, paid bizops offers...
