If you're wanting to send quality traffic to a TGP then you'd better make sure it's a dead end site (no trades), otherwise you'll be trading the good stuff for recycled crap.
You may find in the short term the recycled crap makes you more $$$. Something to consider.
A typical teen TGP with FHGs will probably make you about 25-30c per 1000 FHG loads, so if your prod is 250% and your skim 60% then 1000 site loads = 1500 FHG clicks. The average earnings used to be a lot higher.
