... it worked out pretty good for me:
The two major bonus sites (IMO) are Party and Empire. Stars is too few and far between, but they are offered, and other sites seem to difficult to clear to be profitable.
I get rakeback at UB and EuroBet (a Party Skin). It works out well that I am able to take advantage of Party / Empire bonuses w/out it affecting my rakeback money at the end of the month.
The main problem I have w/ Party+Skins is that they do not offer $2/4 6Max. What is that about? Was that ever discussed? Fuck, that's annoying. The jump from $1/2 to $3/6 is FAR to drastic, so I'm going to have to find something in between.
