I am thinking about opening another poker account on a different site. I currently play on Party, but I am looking for another site to use. Which would be the best one(in terms of bonuses, # of fish, blind structure, etc...)? Is Pokerstars the best option? I've heard people saying a lot of good things about them, but I just wanted to see what you guys thought.
Thanks,
Jah
