Well IMO Bodog are the Nutz
My Best program by miles, even though they go against all my rules of picking a program as they carry neg balances and bundle between their casino, sportsbook and poker room.
I mainly promote them for poker and i find their cross promotion excellant.
Even though ive only promoted them for 3 months i can already see rentention is above average (compared agains other sites i promote)
Their stats are not that good as theres no clicks or downloads, but i hear this will change very soon along with a much better intergrated affiliate back end.
