WPT/WsoP impact on cash games?

[MCS]

Hello,

I'm going to Vegas tomorrow. I understand the Mirage WPT main event starts on Sunday, and that Caesars has some WSoP circuit stuff going.

How does this impact cash games? I'm planning to play $4/8 and $15/30. I figured there will be no impact on $4/8, but I wonder if $15/30 will get some tournament traffic. I'm also not sure if someone playing under their normal stakes is good or bad for other players, i.e., do they often goof around enough to make up for their (possibly) greater skill?

Thanks.
