I have searched the net and you cannot datamine at pokerroom.

Is it worth switching from TowerGaming (a pokerroom skin) to PartyPoker, just so that I can datamine Party?

TowerGaming has the best bonuses that I've seen on the net and there are a lot of fish. Party's bonuses are much worse than TG's (they don't even compare). I've heard Party is also very fishy (probably even fishier than TG).
