Early Tournament Strategy?

[Huggy]

In the early stages in a tournament is it a good strategy to call PF with a wide range of hands hoping to hit a big flop? or isit better to conserve your chips for when your a big favourite and avoid dangerous situations.

I play on UB on low limit MTT's, so getting payed off when i hit a big hand isnt too much of an issue.

I'd like to hear you EXPERT opinons.
