I'm not sure what you are asking. Are you contemplating doing something on the flop that allows you to get away from the hand? If so that can't be right, you should do whatever makes it most likely to end up allin agianst villain. Reraising allin on the flop is the standard method for achieving this. If you just call the flop reraise there might fall a card on turn that scares him into folding. I don't think I could ever get away from this, and especially not against the villain you describe.
