Best iPoker deal?

[ubeticall]

Right now, I'm testing every big network (searching for a good site to settle down). I tried Stars, FullTilt, Ongame and lately Prima. The last one I want to try is iPoker. What is the best (longterm) deal there? I know something about cashback with the accumulated points and got PM's with extra rakeback (from the Affil/Rakeback forum), but the people I got PM's from don't seem to be trustworthy imo. I hope someone can help me

PS: I play NL50 6-max and ~50k hands per month
