I like a call. This allows us to fold if the turn is really bad for us, and might pull in some more callers to give our nut low draw better odds. Repotting also effectively throws away the advantage we have of having position. I think about 2/3 of the deck allows us to continue on the turn (all the remaining A/K/Q, plus the sixteen cards that give us the nut low, and a couple of other hearts that give us the NFD).
For what it's worth, I don't think a fold is out of the question. HU of course our hand is a monster, but with this many callers preflop and two who caught a piece of the flop we're not necessarily in great shape here. No protection for our low and our high needs to improve for us to be good on that side.
