Final Pot: t700

I'm not interested in bluffing away 1/3 of my stack on a re-steal, but should I spend about 10% to see a flop? Seems like if I call there's a decent chance the BB will come in as well. I haven't been at the table long, but neither of these guys has been especially aggressive with their large stacks. The only hand I've played was a push for 8BB's with AQo, so I probably have some equity for a semi-bluff.

You wouldn't know it from the stacks at this table, but I'm about average in the tournament. Should I take a flop or save my money?
