Live NL Flop decision

Here is a problem I see with just calling.

What happens when the turn comes KQJT? You're now splitting the pot with A8-A2

What happens when the turn comes 8-2? You now may be up against a boat with no way of really knowing it.

I think you must reraise. If not all in, enough so that if he calls the reraise its going in on the turn no matter what hits.
