WSOP Non-Main Events

[Metnut]

Did anyone here play in a few of these last year? I'm thinking about flying out to Vegas and staying a week or so to play 3-4 of these events. How tough are the games in these events? I'm assuming they are tougher than the main event due to the lack of satellite players, but maybe there is still some dead money in these games somehow? How much tougher would one of these events be as opposed to say one of the nightly $100+9 or $150+12 multis on stars. Any advice/information would be very helpful.
