You need to raise anyway, even if you don't thin the field. JJ is too good a hand. I would raise to atleast 500. If overcards flop, you may want to check and decide what to do based on the action. It is OK to raise and then fold on the flop. That's the standard way to play JJ in limit: raise preflop, fold after the flop.

If you don't want to play out of position, pushing is an alternative, but that kind of depends on the chance someone is trapping and the chance of getting a loose call.
