Did you try the other ones that CrakRevenue offers? I would suggest a few of them separately for a month or more if possible and see which one brings you the most. I can say that XLoveCam on XLoveCash coverts well with the Western European traffic but they are not that popular as some other webcam sites so it is worth to give them a shot for some time.
By the way, you never know what offers will convert with your traffic unless you try all sponsors yourself.
