Haha...what's your br at now? I don't really play the cash tables, so I don't know what the variance is...but I just asked a good friend of mine and he says a good rule of thumb is that you should never sit at a table w/ more than 5% of your br at one table and if you win 10% of your roll you should get up and start over. Another tip is if you play the SnG's you should have about 25-50 buy ins in your br. I hope this helps, I'm still trying to figure all this out as well...luckily I have some good friends to help =) GL at the tables
