depends,
if you pay your way in the tournament, then it's wise to be cautious and get ITM.
On the other hand, if your stack is large enough then you can take advantage of weaker players who will fold to almost all hoping to get ITM.
If you play mainly
freerolls and you're building stack, then wait, and hit it, but since on almost all freerolls you play for small amount just to get by, I would hit it hard (again) since so many will not risk at all, hoping to get ITM and collect some pennies.
