Honestly. Completely honestly, that does sound better than most of the other alternatives mentioned in this topic so far. Lightning rounds suck donkey dong. There's no way around that fact. And holding a third round exactly like this seems superfluous.
However it still doesn't sound fair. greengravy forgot to vote this round just like Poke forgot to snipe last round. Proclaiming Rick the winner based on the assumption that he would've received more votes if all of his fans showed up feels unclean. And giving Cochran the sole win under any circumstance is just wrong. Morally.
The fairest-sounding idea so far was the dual title, but uh... we kind of need a sole Survivor, don't we?
