Back drag is not a myth. I had never heard the term until I read it here. When I replaced the head on SK 1/4" head with the DT head to double the tooth count, that's exactly what I noticed. It's not enough of a problem to me to care, but I definitely feel it. Installing some manifolds in a tight spot on an Armada at work yesterday, I was expecting it to be an issue, only being able to fit one hand in there, but it went ok once the nuts were past the finger tight point.
