Just found this thread searching for my SN.
Datinggold (the $2 free join+bonus program), AAC, and Iwantu seem to be the combonation that works for me
My traffic sources are about %60 return visitors, so I need to offer a variety of programs to keep getting signups.
But if you have in-and-out traffic (people who probably wont come back) i'd just do datinggold.
