You still have 5 people behind you left to act. I would raise to ~500. This is big enough to take down most pots your all-in will take down. It also protects you from someone willing to reraise again behind you. Any solid player who 3-bets is likely to have AA or KK and you can get away without stacking yourself.

Also, while there may be an exceptionally weak player behind you who may call w/ AQ, AJ hands, you are going to lose most action from the hands you are way ahead of leaving only the hands that have you crused or perhaps are racing with you.
