How do you play AA3x in PLO/8 tourneys?

[modaddy]

Pretty new to PLO/8 so forgive me if this is a [censored] post.

If first in, I assume you usually raise with this hand. Would you call a large reraise with it?

Following several limpers?

Do you re-raise to isolate a raiser? Is this a hand you're generally willing to get all in with PF? Assuming the answer is yes, what is the WORST AA hand you would be willing to get all in with PF... (assume middle tourney, average stack size)

Thanks...
