Just went through the junkshow that is this "beta".
Is it too much to ask for consistency? Things would be much clearer for passengers and much easier for the TSA employees if they put up a few extra signs isntead of just snake the guardrails all willy-nilly to put people in certain places and then randomly pull some out to go through a different version of security.
I'm with Spiff though, they may as well hurry up and have Pre be the way that everyone goes through.
