Should I buy into a Main event?

[renodoc]

Just want some opinions.

My resume:

I'm a budding recreational player with about 18 mos experience now. I cash or win local weekly tourneys with some regularity and recently made two final tables in events with 200 entries at the Peppermill.

I won a seat to play in the WPT event at the Hilton last year ($5100) and managed to bust out after about 3 hours with some horrible weak-tight play. I was nervous and intimidated.

I'm debating buying in this year and taking another shot. I'm a much better player than I was this time last year, but obviously don't have much experience playing at this level. With a goal of making it through the first day with an average or above chip count, who would advise that I go for it, and who thinks its a waste of my time and money. Gaining experience at this level might be worth the buy-in??

Please spare me the "we need fish like you in the tounery" comments....
