how soft IS party 50nl? (compared to FullTilt for example) maybe i should go and clear a bonus there this month, to find out...

Generally first deposit bonuses >>> rakeback (e.g. Fulltilt bonus + rakeback is equivalent to 62% rakeback), but you gotta be able to clear them = know how quickly they clear etc. Best place to look for that is bonuswhores. I figure you should go clear all the good bonuses, that way you'll quickly find which is your favourite site. Clear the regular reload bonuses at the same time.

Best of luck.
