Could someone with experience rate PRIMA (fish/tight?)

[insyder19]

Hey, I played on party, stars, full tilt, pacific, betfair, ipoker and I might move to PRIMA now because I heard of the HUGE rakeback they offer.

But I would like to know how fish or tight they are, I heard there are many scandinavians on it which is pretty good if you are a tight player, they do all the work.

And I find full tilt poker and stars WAY TOO tight, no callers unless decent hands, that would suck if prima is about the same.

Your experience?
