My advice would be to stick with rev share. With a bonus site like mine, you get a lot of hit and run players depositing $25 and $50 to get the bonuses.
You do make rev share off those players, but I guarantee no affiliate program is going to pay you a huge cpa for those type of players. If they do, they will boot you out of the program and you will likely experience the “cpa horror” that so many affiliates have reported.
I find I get more rev share when I promote casinos with recurring bonuses for the bonus players. They may only deposit the minimums, but they will do it until the recurring bonuses run out, and you still have the rev share from those deposits.
Just my opinion… good luck either way.
