Rose,

Yes, TGPs are big bandwidth eaters but You have to live with them if you want to make money with them...
If you dont like their traffic, go for SE and AVS stuff or more specific niche - Its quite clear that you will get lots of teen traffic but very low sign-ups, but on the other hand people looking for something special (pissing? foot-fetish? pregnant?) will have to pull their credit card more often.
My opinion as for TGPs is also not too positive. I am pretty sure without free hosts and stolen content there wouldn't be more than 20% of galleries online and TGPs too. That would of course mean more sign-ups for us...
