I used C-Planet for my US-traffic (ONLY Roulette !!). My problem with them is the low 25% commission (Sorry Ben !!) so I changed to Mainstreet Casino (40%). Mainstreet Casino converts a little bit worse, but to +15% in comission (40%-25% = 15%) really makes up for the lower conversion, so that the change gave me about 10% more average commission from US-Players.
That’s the truth… But I don’t know what’s with NON-Roulette traffic.

PS: Anyway Rushmore has the best tracking stats I have seen so far…
